In My Classroom: Going Bananas for Phenomenon Based Teaching

I originally drafted this “In my classroom” as a way to talk about this cool lab that I used to begin talking about the role of biological molecules in living things.  I originally intended to end this with talk of how it was a great lab experience for my students and made for a good model to explain how living things utilize biological molecules.  This was all before the recent NABT conference when I learned about the work being done by teachers in Illinois to create phenomenon based storylines as a way to teach concepts and practices from the NGSS.  I still intend to say all of those things, but the ending has really just sparked a thousand new fires in my head.  Brad’s use of the lighting of the beacons from The Return of the King is in full effect, and I am seemingly humming the score as I type away.

A few years ago, an inquiry idea got posted in the October 2015 ABT about utilizing bananas as a model for learning about biochemistry.  This year, I decided to utilize the model in my classroom as a way to introduce biological molecules and begin talking about cells and cellular processes.  I started with the bananas in class, giving groups of my students (both AP and General) very ripe, somewhat ripe, and unripe bananas.  I asked them to use their chalk markers and record as many observations as they could, comparing and contrasting the bananas.  I got some predictable responses like their coloration was different, but most made great observations about the texture, mass, and taste of the bananas.  My favorite interaction was when one adventurous student informed the class of the taste and consistency of all the banana peels, pointing out that the unripe banana appeared to have a higher water content in the peel compared to the riper specimens.

So after all these observations and in class discussion, I directed students to use the two chemicals I had provided them (iodine and Benedict’s solution) and create an assay to observe how they affected the various bananas.  We made some observations, and recorded our qualitative data from what we saw.  This lead to me revealing that Iodine serves as an indicator for starches and Benedict’s for sugars.  At this point we talked about carbohydrates and their overall structure, pointing out that polysaccharides like starches are formed from sugar monomers like glucose.  We could see clearly that one banana was strongly positive for the presence of starches while the other was more strongly positive for sugars.  This lead to me posing a question.  How did all those starches seemingly disappear, and the sugars replace them?  

My students sat on this for a second.  I had to prove that I had not injected them with sugar.  Students teetered around an answer, but I eventually had a student in each class suggest that the starches are being digested.  I had one student go so far as to name drop amylase.  This lead to us talking about chemical reaction that are occurring to break these polymers up into simpler pieces.  We modeled what they looked like and investigated the role and structure of proteins, particularly amylase.  With the last few minutes of class, we broke out the microscopes and identified cells that had been stained with iodine to indicate the location of starches in the cells.  My students were super engaged with the whole process.  We had a small writeup to summarize and model the processes we had observed.  But that was kind of the end. We still talked about these things in class, but I left a pretty cool phenomenon just hanging there.

A student slide of unripe banana stained with iodine to highlight the presence of starch (in this case amylose).

As previously stated, I got to see some awesome phenomenon based teaching from my experiences at NABT, and am looking at next steps with my students.  Jason Crean from the Illinois Association of Biology Teachers has formulated these NGSS storylines in his class following specific organisms and phenomena.  His phenomena are very heavily focused on real data from collaborations with zoologists and some of his work can be found at   His focus is on how all of the content standards in the NGSS connect to each other in an engaging and coherent storyline, all sparked by an investigation into a particular phenomenon.  

While thinking about writing this post, it occurred to me that the banana lab seems like a great piece in the puzzle to start my own conceptual storyline unit on how “We are what we eat.” In my head, this will be something that delves into why some people have trouble processing certain foods and how malnutrition affects us.  I have shared a little bit about this idea already on a Facebook post, and am now looking into a collaboration to produce some conceptual storylines that follow phenomenon, not just the order the standards are packaged and delivered to us.  I realize there is safety there, but safety has never been fun.

Data Analysis in a Natural Selection Simulation

+/-1 SEM bars added

I really like the HHMI Biointeractive activity “Battling Beetles”. I have used it, in some iteration (see below), for the last 6 years to model certain aspects of natural selection. There is an extension where you can explore genetic drift and Hardy-Weinberg equilibrium calculations, though I have never done that with my 9th graders. If you stop at that point, the lab is lacking a bit in quantitative analysis. Students calculate phenotypic frequencies, but there is so much more you can do.  I used the lab to introduce the idea of a null hypothesis and standard error to my students this year, and I may never go back!


We set up our lab notebooks with a title, purpose/objective statements, and a data table. I provided students with an initial hypothesis (the null hypothesis), and ask them to generate an alternate hypothesis to mine (alternative hypothesis). I didn’t initially use the terms ‘null’ and ‘alternative’ for the hypotheses because, honestly, it wouldn’t have an impact on their success, and those are vocabulary words we can visit after demonstrating the main focus of the lesson. When you’re 14, and you’re trying to remember information from 6 other classes, even simple jargon can bog things down.  I had students take a random sample of 10 “male beetles” of each shell color, we smashed them together according the HHMI procedure, and students reported the surviving frequencies to me.

Once I had the sample frequencies, I used a Google Sheet to find averages and standard error, and reported those to my students. Having earlier emphasized “good” science as falsifiable, tentative and fallible, we began to talk about “confidence” and “significance” in research. What really seemed to work was this analogy: if your parents give you a curfew of 10:30 and you get home at 10:31, were you home on time? It isn’t a perfect comparison, and it is definitely something I’ll regret when my daughter is a few years older, but that seemed to click for most students. 10:31 isn’t 10:30, but if we’re being honest with each other, there isn’t a real difference between the two. After all, most people would unconsciously round 10:31 down to 10:30 without thinking. We calculated the average frequency changed from 0.5 for blue M&M’s to 0.53, and orange conversely moved from 0.5 to 0.47. So I asked them again: Does blue have an advantage? Is our result significant?

Error bars represent 95% C.I. (+/- 0.044) for our data.

Short story, no; we failed to reject the null hypothesis. Unless you are using a 70% confidence interval, our result is not significantly different based on 36 samples. But it was neat to see the interval shrink during the day. After each class period, we added a few more samples, and the standard error measurement moved from 0.05 to 0.03 to 0.02. It was a really powerful way to emphasize the importance of sample size in scientific endeavors. 

Should the pattern (cross-cutting concept!) hold across 20 more samples, the intervals would no longer overlap, and we could start to see something interesting. So if anyone has a giant bag of M&M’s lying around and you want to contribute to our data set, copy this sheet, add your results, and share it back my way. Hope we can collaborate!

Was in my Classroom: A Biotechnology Program

I got some really great news recently: some of my biotech students from last year are insisting that the program live beyond my tenure. The students who persist are not your typical advanced science participants (both were new last year and had zero science training beyond their graduation-required science courses). They found a sense of purpose and belonging and I’m really moved that they are exercising their agency. The program is more than the principle investigator.

My Report: By Michael Ralph

They have a new sponsor and the question has turned again to, “What the heck is the Biotech program at Olathe East?” This is an open letter to the new sponsor, and I share it here so my debrief can be of value to anyone else considering something weird. Here we go.


What Would Professionals Do?

Keystone Habit #1: BE a Research Lab

We did everything like a grant-funded university research lab. Every question was, “How do professionals do it? We will do it like that.” There was no pre-planned curriculum. There were no tests. There were no points. One thing matters: the question. Can we get methanotrophs out of there? The joke gets made frequently that, “[some biology topic] could be a whole course right there!” Ha ha, but it won’t be… Well, this was that course. From day one, I assigned new students to help me address my question. Train on taking water samples, learn to cell stain, build me a sensor… we’ve got stuff to do. When they needed chemistry to mix the Nitrate Mineral Medium 2014 (NMM14), we’d stop and learn it. When pressure gradients were needed to understand a sampling design, we’d learn that too. Professionals have meetings, so we had them. Professionals present at conferences, so we did that. Professionals do outreach, so it’s on the calendar. WWPD, all day every day.

When students started to become more comfortable in the space, they invariably start having ideas and asking questions. We’d follow the postdoc model and let them split their time. My veterans of several years would have the freedom and authority to oversee an entire research team. Students specialized and began to follow their own interests, while still having responsibilities to the original investigation.

Take home recommendation: craft your own driving question. It’s got to be really good. Then focus on nothing else.


Only one thing I can’t use… a credit card.


Keystone Habit #2: We’re Cheap

Necessity is the driver of innovation. We performed robust biogeochemical analysis with scraps and pennies. Only 1 of our 5 years did we have any dedicated budget (it was in the middle and it went away again). Scrap lumber from theater, scrap electrical from district contractors, spare keyboards from IT, waste planters from horticulture… being efficient scrappers was so ingrained in everyone’s attitude that when we did the final tear down I had to throw many of the items away myself because students could not be convinced anything was trash.

Big flashy equipment is a crutch when students don’t yet understand the fundamental concepts they’re investigating. When you really commit to finding a way, it’s amazing what you can make work. 3D print parts rather than buy them. Leftover dry ice in shipping materials. Creating long-term storage cultures in the freezer rather than reordering. Mixing your own bacterial media instead of pre-made. It makes the program cost-effective and the students see more of what goes into the project. They understand the bacterial medium because they had to make it. Sterilization makes sense because it was a total pain to sterilize that equipment.

Take home recommendation: fancy equipment and protocols are not the point. They take great pictures, but they aren’t science. This stuff is hard and making any arbitrary technique the course focus will obscure what it actually means to learn in a biological research space.


Anyone can help those who can already help themselves.

Keystone Habit #3: We’re Inclusive

A good driving question is both accessible and complex. That means nobody who hasn’t intentionally trained in that area will have strong background knowledge on how to investigate it. The end result is who cares what level of math they’re in?!? AP Biology students know as much about methanotrophy as freshman (in every practical sense). We have a serious exclusion problem in high school science; don’t be a part of that problem. Any student… ANY STUDENT… who is interested and willing to join should be welcomed. I have a litany of “not science students” in my alumni base who made powerful contributions to our project. I had freshman leading research teams, remedial students self-identifying as mycologists, and more.

There are plenty of biotech programs out there, collegiate and high school. They are picturesque spaces with students in lab coats wearing goggles staring intently at test tubes. They burn through budgets and look great on resumes. The problem with these programs is the course has become about the techniques. Put your hands on an electrophoresis chamber. Check. Touch a thermocycler. Check. These are Petri dishes. Moving on. Biotechnology in the industry sense is a highly derivative field that requires expertise in more than a half dozen disciplines. Our high school students are not that. Indeed, the few who can be have boatloads of options for how to pursue enrichment. The world doesn’t really need an expensive, esoteric course to serve the 1 or 2 students a year ready for that kind of work.

Take home recommendation: Get Them All Involved. I’m not saying tolerate distraction, destruction or ineffective behaviors. What I am saying is it’s easy to quibble with the all the other programs about that top 3% of students who will spin gold in any classroom. Instead, find all the other students who just want to do something meaningful… and give them some sweet science to explore.


There’s so much more I think and want to say, but ultimately this post is prompted by students. Let the program be theirs. For that matter let it be yours too. Don’t investigate methanotrophs, find your own thing. Let the students help you decide what that might be. Talk with others in the field when you need help. The putting greens are pleasant, but well-traveled. Get out in the weeds a bit.


And post about it. A very proud former investigator will be following your progress.

In My Classroom: NESC Videos are helpful

I have a student-teacher this semester, and he asked to teach our evolution unit as his “portfolio” unit. He is, at this point, mostly being left on his own to plan, assess, and manage the classroom. Our students were all on board for the Geologic Time Scale and natural selection (and it’s accompanying demonstrations and labs).

However, as we started talking phylogenies and focusing on ancestry, a handful of students started asking why people thought we evolved from monkeys, and why monkeys weren’t evolving into humans. I knew as a more experienced teacher (who had made many mistakes already while teaching students), that this kind of questioning is preventable with some different organization of your unit. But I was interested in how he would confront this in his classroom because it would tell me a lot about his progress and readiness to handle his own classes. As a cooperating instructor, I was interested in how he would respond to this. As a fellow biology teacher, I could sympathize with how he was probably feeling; even if you do everything perfectly, address every misconception, incorporate the nature of science into every lesson, this type of question is always going to get asked by somebody. So what did he do? He impressed me.

I have used “tree-thinking” quizzes and other resources available from Understanding Evolution but have never used any of their video clips. My student teacher had some productive discussions about making conclusions from evidence, why scientific explanations have to be falsifiable, and what it means to have a “common ancestor”. He followed all of that up with this video:

I had never seen this before, but our students really responded well to it. It is definitely something that I will be using in the future!

More Understanding Evolution and National Evolutionary Synthesis Center videos can be found here.

And perhaps it is time to remove my padawan’s braid.

Get Out and Get Data…

In September of last year, the University of Kansas Biological Field Station graciously opened its facilities to the environmental science students of Basehor-Linwood High School. Scott Campbell, associate director of outreach and public services for Kansas Biological Survey, received the 20 students at the Armitage Center. Scott, a true educator, engaged the students in a discussion about the broad mission of the field station. Students curiously asked many questions about the current research that was being conducted.

Students received some general guidelines about how to treat the animals ethically. Soon students began a fierce competition to catch the most frogs. In the classroom a discussion about population surveys would have been met with little excitement. At the side of the pond, with frogs leaping through the cool September grass, there was not a student in twenty who thought this was a meaningless exercise. The excitement was palpable.

Once the frogs were collected , students retired to the Armitage Center for sack lunches. The frogs were cooled in a large refrigerator to make them easier to work with. Students had practiced weighing and measuring frogs in the classroom. Now these skills were put to work- there were 134 frogs to weigh, measure, and score for color patterns.

This scene was punctuated by moments of chaos when a frog or two would make a dive to get out of the grips of the high school students. After all the data was collected students returned to the pond to release the frogs. On the way, Mr. Daniel Smalley, their teacher, caught a small black snake.


The snake made its way to Mr. Stan Roth who is an adjunct research assistant and educator for the Kansas Biological Survey. Stan identified the species and engaged the students in a conversation about the natural history of the snake. Many students touched a snake for the first time.

Finally, students were able to seine in the pond. They had a good harvest of small fish and invertebrates.

Before the students returned to class they visited the Rockefeller Prairie and walked the trails. Students collected 10 flowering heads of goldenrod. The flowering heads were quickly covered in gallon ziplock bags and sealed shut. Inside all the insect species that were foraging or hunting on the flower heads were sealed too.

Back at school the students compiled the data into a Google spreadsheet. This data was then analyzed and graphed by hand. Thus, students had the chance to analyze data about a population that they had collected. Mr. Smalley then entered the information into Plotly an online graphing platform. The computer allowed the students to more easily analyze the distribution variables like snout to vent length and weight.

The final graph that students examined compared the length of frogs to their weight. Mr. Smalley explained that we should expect to see a strong connection between these two variables. Further, he explained, that this was an example of a mathematical model that could be used to predict and explain the population. Who knew there could be so much math in environmental science?

After the frog data was analyzed students took out ten bags of Goldenrod. The bags had been frozen. Students separated out the insects from the Goldenrod. They had to identify the insect species. Thankfully, Mr. Smalley has had a lifelong obsession with collecting bugs so with his help and a few field guides students quickly were able to determine the species they were looking at. Mr. Smalley then helped the students put together a food web based on these species. The bugs could then be categorized by their tropic level . Students collected the bugs of similar trophic levels together. This included 14 jumping spiders that served as top predators! Each level was weighed together. The students turned this into a large bulletin board that was displayed in the hallway. Mr. Smalley explained that this too was a model that showed where the biomass (a proxy for energy) was located in this micro community. Students really took to the project and decided that It would be good to include the actual organisms. Thus, all 14 spiders, herbivorous insects, and Goldenrod flower heads found their way on the bulletin board.

Experiences like this empower our youth to see themselves as shareholders of knowledge rather than passive vessels who blithely learn facts about things like ecosystems only to recite them back on tests.

In My Classroom: Reading Peer-Reviewed Papers

Welcome to the KABT blog segment, “In My Classroom”. This is a segment that will post about every two weeks from a different member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it.

The idea is that we all do cool stuff in our rooms and to some people there have been cool things so long that it feels like they are old news. However, there are new teachers that may be hearing things for the first time and veterans that benefit from reminders. So let’s share things, new and old alike. When you’re tagged you have two weeks to post the next entry. Your established staple of a lab or idea might be just what someone needs. So be brief, be timely and share it out! Here we go:

This year I am teaching a class that is new to me called “Honors Biology 2”. This course is split into Genetics the first semester and Microbiology the second semester. I was given a rough curriculum for the course and was encouraged to make it my own. Having only taught Freshman Biology last year (which was my first year teaching) I was a little nervous about how to challenge these students.

On the second day of school I asked my students to write down everything they could tell me about DNA. I not only got full molecular structures with phosphodiester bonds labeled, but some students drew full replication forks with all enzymes labeled. My next days’ lesson for reviewing DNA structure and replication was scrapped and I came to class the next day with 70 copies of Meselson and Stahl’s original publication.

My smarty-pants students said “they proved DNA replicates semi-conservatively”, to which I said “how did they prove that?”. Shocker, but they didn’t have a response.

So we started into it. I gave my students a CER form and asked them to explain the evidence provided in the paper for how DNA replicates. They ended up needing 3 full class periods to get through the paper and really understand it, and they complained all three of those days. After students understood something they would say “why didn’t they just say that in the paper” or “why did that have to be so difficult” which lead us into good conversations about the content as well as science in general.

Despite my students’ grumbles we have read 4 scientific, peer-reviewed papers this year. For our most recent one, titled “A microbial symbiosis factor prevents intestinal inflammatory disease” I had students create a mini-poster that describes the experiment. I’ve also had students summarize each paragraph of these papers into one sentence, re-do a diagram in the paper, use the thing explainer method to explain the paper, or draw a graphic novel explanation of the paper. We have gotten to the point where students don’t actively hate these papers and have started to see them as a cool way to gain new information.

An example of a mini-poster that explains the research. Note the diagrams taken from the paper and the dead mouse.

I’ve used these papers to introduce new ideas or elaborate concepts with recent research. The thing I’ve found most rewarding as a teacher is how confident my students feel once they are able to explain these difficult readings. They face a challenge, overcome it, and then feel really great about it. It has also forced them to “think like a scientist” if I ask them things like “why did they do it that way”. Several parents have said things like “I couldn’t even understand the title of that” or “my student came home and explained this to me”. I haven’t had my Freshman biology students read a full paper (yet), but have had them read abstracts or analyze some cool diagrams.

That’s all for me. Sorry for going way over my 250 word limit. Kelly Kluthe is next at her own request!

P.S. thanks to Eric Kessler’s how-to for helping me stop making excuses for posting!

In My Classroom: Investigating Mosquito-Borne Diseases

Welcome to the KABT blog segment, “In My Classroom”. This is a segment that will post about every two weeks from a different member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it.

The idea is that we all do cool stuff in our rooms and to some people there have been cool things so long that it feels like they are old news. However, there are new teachers that may be hearing things for the first time and veterans that benefit from reminders. So let’s share things, new and old alike. When you’re tagged you have two weeks to post the next entry. Your established staple of a lab or idea might be just what someone needs. So be brief, be timely and share it out! Here we go:

I’ve been meaning to post about this project for a while now. This was our first major research project for my Biology 1 students this year. With Zika in the news all summer, I wanted to do a project incorporating mosquitos.

My vision for the project was to have students collect mosquito eggs, hatch them, then raise them in observation chambers subjected to different experimental variables. At the end, students would use their data to draw conclusions about mosquito behavior and life cycles. Students would collect data on the number of days until adults emerged, how temperature affected emergence rates, whether males or females emerge faster, and the percent of eggs that would make it to adulthood. Then students would use this information to develop a plan to slow the spread of mosquito-borne disease.

I stress that this was my vision because this experiment didn’t work so well in reality. My students made oviposition traps using Solo cups, following the method outlined here:, which is a wonderful citizen science project (talk to Noah Busch for more information!). Some groups decided to make more complicated traps. We placed the traps around campus, testing different types of sites, but we collected very few eggs! I was surprised by this result, but I found an aquaculture company to purchase mosquito larvae (Sachs Systems Aquaculture:

After this initial hiccup, we had enough larvae to carry out the experiments in the observation chambers. I followed the chamber design from HHMI ( Some groups studied the effects of various temperatures, some studied the pH of the water, some wanted to look at the effects of light, among other things. We couldn’t afford as many larvae as I wanted, but we made things work by combining classroom data for students to analyze.

Once all of the data was collected, my students made their conclusions about mosquito control methods. They presented their findings and ideas using posters. We had a poster walk, and students were encouraged to share feedback with each other.

In My Classroom: Investigating Energy Flow with ZOMBIES!

Welcome to the KABT blog segment, “In My Classroom”. This is a segment that will post about every two weeks from a different member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it.

The idea is that we all do cool stuff in our rooms and to some people there have been cool things so long that it feels like they are old news. However, there are new teachers that may be hearing things for the first time and veterans that benefit from reminders. So let’s share things, new and old alike. When you’re tagged you have two weeks to post the next entry. Your established staple of a lab or idea might be just what someone needs. So be brief, be timely and share it out! Here we go:

Investigating Energy Flow with ZOMBIES!


The Set-Up

It’s the zombie apocalypse! You have a safe fenced-in area that is impenetrable to the zombies.  But, you also cannot leave the fenced in area. If you had time to prepare this land, what would you plant? What livestock would you have? (Note: Students have the option of doing a Mars Biodome if they do not want to do the zombie apocalypse.)

Student groups are all given the same 11 x 17 inch grid paper. Each square equals 100 square feet. Each student needs a housing structure(s) that equal 20×25 squares.


The Goal

Sustain as many humans as possible using the land space given. The group who can sustain the highest number of people wins. The criteria for sustainability is 2,000 calories per day, per adult (730,000 calories per year). (Note: No stockpiling allowed).

The Work

Students need to find the total number of producer calories from all their crops. (Find the calories / square foot for each food, and then multiple by the number of total square feet.)


Then, students need to calculate how many of those producer calories are actually available for human consumption. To do so, students must figuring out how many of those producer calories their livestock will consume per year.


The only livestock here was goats, if you have different species of livestock you’ll want to add those together to do this calculation.

Next, students need to find the total number of anaimal calories produced. They calculate how many calories of meat (or eggs/dairy) each animal produces. (To simplify, one could assume the entire weight of the animal is meat.) Students do this for each type of livestock and add it together to find the total number of livestock calories produced. (If you have any secondary consumers, they will take a whole other set of calculations!)

Next, students find out how many calories their land produced for human consumption. They take the number of plant calories available for humans and add it to the total number of animal calories produced. Then, they divide that by 730,000 (the total number of calories needed per human per year) to see how many humans they can support.


Getting the Numbers

To make it easier, you could provide a list of several crop and livestock options with their calorie information. But, for me, one of the best parts of this project was having it open ended for the students. I have my students find the information on their own, but they have to back it up with a credible source. This gets pretty competitive, so the students really hold each other accountable.


Here are some important questions that we discussed after completing this project:

Goat image from Microsoft clip art

Goat image from Microsoft clip art

  1. Why do we lose calories when we feed them to livestock?
  2. What is the “best” crop? (calories vs. nutrients)
  3. Should we be putting plant calories into livestock?
  4. What are the pros and cons of having livestock?
  5. What would be the “best” livestock? (For example, for many reasons crickets are much more energy efficient than cows.)
  6. What does this make believe scenario have to do with the real world?

Tips and Suggestions

I suggest you have a running list of “rules” that you as a group decide upon throughout the project. For instance, someone will probably ask if it’s okay to do a rooftop garden. Whatever you decide, you should keep documentation of the “rules” your class makes. The students get pretty competitive and this is helpful.

To simplify our model, we assumed a lot. 1) People only need calories to survive, not certain nutrients. 2) We have sufficient water, fertilizer, and everything else needed to grow the crops. 3) We can store crops up to one year, and there is no limit to the type of crops that can be planted due to climate, etc. 4) Animals can only eat the part of the plant that humans eat. 5) All animals reproduce each year. 6) We eat the entire weight of the animal in meat. And more. But, these assumptions lead to fantastic discussions! I have students write about them for part of the end paper. They are also great opportunities for extensions.

Even with all of the assumptions and simplifications, the students were really able to “get it” in terms of energy transfer and the 10% rule.

I know KELLY KLUTHE has some cool stuff to share! Tag, you’re it!

Staying Positive in Uncertain Times


Welcome to the KABT blog segment, “In My Classroom”. This is a segment that will post about every two weeks from a different member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it. This is not one of those posts. Not really, at least. 

If you aren’t following the news and/or don’t live in Kansas, you might not know we’re having a bit of a budget issue which has impacted our schools and might result in teachers not getting paid for the work they’ve already done. My aim here is not to be political, but if you would like to discuss that side of things, please let me know. Needless to say, there is blame to pass around, and while it may not be evenly spread among our three branches of government, it probably doesn’t all go to the same person/place.  At this point, the problem is there, and we can only work to solve it; pointing fingers and assigning blame will NOT serve in the best interest in our students, and will NOT get schools open in the fall. So I will not (for now) fall into this partisan trap, and I will trust in the process.


I often tell my students “all you can do is all that you can do”. None of what I am doing is work specifically in the contract I signed at the beginning of the school year, and I won’t be paid for any of it. And none of what I am doing is particularly unique. In every district in this state there are many like me, and I am sure several working harder than even I can imagine. In this strange time, it is important for us to stick together, and for us to continue to shout out our friends and colleagues for the amazing work they’re doing. Be a beacon of hope to your students, colleagues, and communities, so they know there is someone who cares about their kids as much as they do, and who is working for them no matter the odds.


The members of the KABT are amazing teachers who inspire me every day to get better at my craft, and to learn more content. They are explorers and innovators. There are people giving up their ENTIRE summer break to participate in RETs (go Jesi!). There are people offering summer classes and science camps (proud of you, OBTA Kluthe). There are many people working on Master’s degrees in education and biology.  And there are people who, despite no indication that anyone in power cares if we are working August or not, are tweaking, perfecting, adding, revamping, or collaborating to make the best possible learning experience for their students. Why? Because they are professionals who are going to do the job they were and are contracted to do, they’re going to be ready when the fall semester starts, and they refuse to compromise on the quality of their work because they know doing so may do irreparable harm to an entire generation of students.

What am I doing in my classroom? I am learning and trying to make myself a better teacher so that I can be considered worthy of the company I keep. I am creating connections with researchers to get my students equipment and experiences to enrich their classroom lessons. I’m writing grants so that my school’s already tight budget has a little less stress on it. I am starting a transition away from traditional grading schemes and moving towards standards-based grades with students being accountable for their curriculum and the evidence demonstrating they know the content (based off of the work of Camden Burton and Kelly Kluthe). I’m working on learning a new LMS (Canvas) so I can be as close to an expert as I can be when our first day of inservice rolls around in August when I know others will have questions. I am presenting to several teacher groups on topics I’m passionate about. I’ve rearranged my classroom and lab environments to make them more open to learning and sharing. (Not to mention my “little side project” as daddy-daycare provider to a two year-old girl.)

Keep up your amazing work, everybody. Share what you’re up to this summer (in or out of the classroom) on our Facebook page. I can’t thank you enough for what you do!

In My Classroom #13 – Curators of Natural History

Welcome to the KABT blog segment, “In My Classroom”. This is a segment that will post about every two weeks from a different member. In 250 words or less, share one thing that you are currently doing in your classroom. That’s it.


The idea is that we all do cool stuff in our rooms and to some people there have been cool things so long that it feels like they are old news. However, there are new teachers that may be hearing things for the first time and veterans that benefit from reminders. So let’s share things, new and old alike. When you’re tagged you have two weeks to post the next entry. Your established staple of a lab or idea might be just what someone needs. So be brief, be timely and share it out! Here we go:


Students in my classroom recently completed a project based learning unit centered around the driving question ‘How can we, as museum exhibit designers, build a museum exhibit about a somatic cell type that will engage younger audiences?’ The question came about as a collaboration between myself, Jessica Popescu, who teaches one door down from me, and the staff at the Columbus Museum in Georgia, most specifically Rebecca Bush, the curator of history. The project consisted of students working in teams of three to four. The teams first divided themselves up into specific roles and selected a somatic cell type to research and display. The potential roles each had real-world parallels in the museum industry. Role options consisted of a marketing director, a manipulative designer, an application letter writer, and a presentation specialist. The Columbus Museum emphasized how these roles relate to their real world job responsibilities in a video displayed to the students early in the project. The video also included several example exhibits within the museum and information as to what type of items the staff looks for in a museum exhibit.


The reason we decided to have students design their exhibits around a specific cell type, as opposed to just ‘animal’ or ‘plant’ cell was to help students understand the interactions, and the importance of those interactions, between different cells in a multi-cellular organism. Students had baseline knowledge of cell organelles, the cell membrane, and cellular transport when the project began.

Exhibit 1

The project as a whole was very successful. Students created a variety of excellent products, a few of which are pictured in this post. Additionally, students took pride in displaying their exhibits to students from a variety of different classrooms. Also present for presentations and ‘museum walks’ were teachers from throughout the school and various members of the administration. The students will also receive feedback on their final products from the staff at the Columbus Museum. One of the most significant signs of success to me was the way in which students generated questions throughout their research. A moment that sticks out to me occurred as a student attempting to do the bare minimum and simply draw a picture of a red blood cell (their cell type), asked the question, ‘Why don’t red blood cells have many organelles?’ This question led him down a path of discovery that led to another question, ‘If red blood cells don’t have a nucleus, then they probably don’t have DNA which is needed to make protein, so how in the world do they have a large supply of the protein ‘hemoglobin?’ Another example of a questioning attitude is drawn from Mrs. Popescu’s classroom. A group of students researching cone cells asked another group why they decided to color their cone cell model yellow when humans only have cone cells for red, blue, and green.


In completing the project next year, I will strive to offer students more opportunities at receiving feedback before the final displays are done. Also, while the student generated questions were awesome, my goal is to structure the project so that more students begin asking these types of thought provoking questions.


Happy holidays everyone, and now I’ll throw it back over to Brittany Roper for the first post of the new year.
