Johnson County Science Cafe

Johnson County Science Cafe’

Observations on Tanzanian Animals, Ecology, and Culture

Speakers: Harry and Charlotte McDonald
              
Date: December 3, 2013

Time: 6:30 pm

Location: Coaches Bar and Grill, 9089 W. 135th Street, one block west of 135th and Antioch, south side of 135th St.

Harry and Charlotte will share their thoughts (and dare we say, insights) on Africa from their trip to Tanzania this fall. They will share their pictures and others from the trip as well as perspectives gained from their personal observations, from information provided by their guide, and from additional research. In the spirit of scientific conversation, all are encouraged to share their own stories and opinions from trips to the Dark Continent.

Harry and Charlotte are retired science teachers, naturalists and avid bird-watchers. Along with the usual cast of characters to be seen in Tanzania, they were able to identify over 160 species of birds and will share stories about many of them. For those of you that remember the tales of Tarzan and references to an elephant graveyard, Harry and Charlotte will suggest one possible inspiration for that legend.

Join us next Tuesday.

Evolution of Multicellularity?–a New Lab Opportunity

Perhaps you follow Carl Zimmer and are familiar with an ongoing set of relatively simple experiments that explore the evolution of multicellularity using yeast.  The experiments are very straightforward and I had thought to myself that if I were still in the classroom I’d be trying this out.  William Ratcliffe, one of the principle researchers involved, was at NABT presenting a high school adaptation of the investigation as well as another on testing the predation hypothesis as a possible driver for multi-cellularity.   Even better he was distributing kits.  He want folks every where creating multicellular yeast.

You’ll find a number of relevant links below but for now the important one is:  http://snowflakeyeastlab.com/index.htm  Head on over there and request a kit and give this a try in your classroom.  Very, very cool.

 

A caveat, not all of the research community is on board just yet with this serving as a appropriate example for the transition to multi-cellularity.  Carl discusses this in his posts linked below (along with some responses from Dr. Ratcliffe.  You can also find additional critique here on Sandwalk, Larry Moran’s blog:  http://sandwalk.blogspot.com/2013/11/is-bakers-yeast-good-model-for.html

A Little Birdie

The role of social media is rapidly evolving, but education can still be a part of those interactions.

 I am a millennial.  I was a college freshman when Facebook exploded in popularity, and although I was reluctant to join I have been a part of the social media giant’s clientele long enough to watch it mature over several turbulent phases.  There was a time when Facebook was essentially a repository for mementos from the past weekend’s… social activities.  The idea of having more benign social interactions via social media like Facebook and Twitter still doesn’t sit quite right with me, but I would argue that is indicative of my increasing age and not the current role of those services in students’ lives.  That shift also means social media can play a role, albeit a dynamic one, in education.

My AP Biology students have always formed an AP Bio Facebook group to collaborate on their work throughout the year.  I never suggest it to them and I refuse to be a part of it personally, and yet every year it happens.  Biology is a big part of their lives and so it is perfectly natural that they have it represented in their social media presence.  Later in the year we use the group to share lab data, organize review sessions, and get help on difficult material when there are questions.  This kind of peer support is amazingly valuable, and this kind of behavior is something many teachers try to force with very limited results.  Somehow, Facebook is better at encouraging scientific collaboration than I am.

My Biotechnology program is also wrestling with communication problems this year.  I spent at least 12 hours during the summer setting up an online lab notebook system.  There were spaces for each individual research project, organized tables for data, systems for assigning tasks and culturing deadlines, and much more functionality that would allow the whole lab to run seamlessly without any direct daily supervision from me.  Not one single student wanted to use it.

They all agreed we needed a new communication system to replace the paper notes that littered the lab.  Yet not one would willingly use the Sparklix system I had setup.  A month into the school year a senior decided to setup a Google+ community for the lab group to use.  The system was 100% redundant and had zero support from me.  The picture below is our group recently:

Biotechnology Google Community – In Use

One of my students developed a system in 30 minutes that I couldn’t get off the ground after a dozen hours and several weeks of prompting with students.

All of this experience with social media has led me to the conclusion that most of us will struggle to predict the role of social media in our students’ lives in the future.  Where we are now is not where we were five years ago, and I’m betting we’ll be somewhere else again in five more years.  However, we don’t have to understand or fully control social media to make use of it in facilitating student learning.  A recent assignment I gave required students to summarize life cycle information into a “tweet” format.  This was good practice with summarization, and provided the logical extension that students could tweet at me if they wanted to.

#TweetAtMe

I don’t maintain an educational Twitter account.  I tweet a couple times a month, and they are just as often silly musings as quality content.  Despite the unpolished nature of my account, it is authentic and real.  Students were immediately engaged by the legitimate nature of the interaction, and have taken to the Twitterverse to come up with interesting or clever tweets about their organisms.

 I actually had students follow my account while I was still giving instructions for the assignment.

They may be using their phones during class…

All it took was a little encouragement and willingness to try.  Don’t force it, but recognize when students could really use what is already a big part of their lives to engage with your content.  Students may surprise you with the great ways they can use their social media to enhance their learning, because they sure surprise me.

I asked two students in my Biotechnology program to write a short piece to share about their views of social media today.  Here are their thoughts:

Every day, students are using social media, but they are not the only ones using websites to stay connected. Classrooms are also employing websites like Edmodo which are valuable resources for students to keep up with their homework during their busy lives. The Biotechnology Lab group at Olathe East High School in Olathe, Kansas is currently conducting research on methanotrophs(prokaryotes that utilize methane as their sole source of energy) in the local area. With students in differing grades, it can be difficult to find a time to meet. To keep connected, everyone is on a Google+ Community to stay updated on lab progress,upload videos, and write posts on individual progress. By allowing students to upload videos of them speaking, those who dislike writing are still able to get their point across clearly and efficiently. This way, students are able to get information from other students from both school and home. Another website that the Biotechnology Lab uses to store files is Sparklix. This website holds files that the teacher uploads, and the lab participants are able to view and save them. Social media may be a large consumer of precious time in students’ lives nowadays, but when used correctly, it also helps students learn and stay connected with their teachers and peers.

Facebook is still not a good place to create a primary class website (heck, it’s blocked in most buildings anyway).  I don’t follow my students on Twitter, but I allow them to follow me so maybe I can sneak some science into their lives outside of school.  I think social media can be valuable if we don’t take ourselves too seriously and are willing to use the media in an organic and authentic way.  Be funny, be social, and let the science happen on its own.
