Photographs from the Fall KABT Meeting

September 16, 2008 in KABT Meetings

I have created a pdf file of selected photographs from the KABT Fall Meeting last weekend.  It should automatically open within your browser assuming that you have Adobe Acrobat Reader.  I used Abobe Photoshop Album Starter Edition 3.2 to create the file.  It is easy to use and a FREE download from Adobe link provided.  Also, you can right-click and save any of the images that you would like to segregate and keep.

I had an enjoyable time, and I hope you did too!

Milkweed for the Monarch larva

September 14, 2008 in KABT News

The KABT Annual Fall meeting was excellent!  I, too, liked getting the larva from Dr. Taylor.  By Sunday evening, the milkweed leaf was devoured…..so, in nearing darkness, I set out to look for milkweed!  I had to stop and think about where I was going to find it…..in a ditch was what I came up with.  I noticed in the last light of the evening that the milkweed plants have a pretty light colored leaf now, but the shape is still that characteristic oval shape.  So in the Topeka area, just driving out to the nearest “country” (actually just past 37th and Gage), I was able to yield 4 common milkweed plants that I collected and will take into the classroom tomorrow.  What was I thinking….more mouths to feed!  But my students will love them!  Thanks again for a great day on Saturday!

Finding your way to the Fall KABT meeting

Here’s the google map to the Fall KABT meeting. I dropped the pin in the parking lot. If you click on larger map and zoom out, you’ll be able to “ask for directions” from your address to KU up at the top of the map. See you Saturday.

Blackworm Lab for Beginning the Year

Here’s my favorite lab for the beginning of the year: Blackworm Lab

I modified information and labs from the iconic Charlie Drewes, formerly of Iowa State University, and Randy Dix of Olathe North High School and gave it a special twist I learned from Sandy Collins of West Junior High in Lawrence. For further information on Lumbriculus variegatus you can visit Charlie Drewes’ website which is still being maintained at the university and is a treasure trove of labs and activities with invertebrates.

Sandy’s idea that I love has students creating labs and experimenting with organisms they believe are being exposed to stimulants and depressants. After they have all completed the lab you tell them that although the water containers were labeled differently, there was no actual difference in the water. I find we can then launch into rich discussions of the reasons for blind and double blind studies AND how some of the greatest discoveries have come about when scientists got unexpected results and strove to understand and uncover what had really happened.

I also find that during the lab some students get data they believe to be wrong (no difference in pulse rates between the groups). They come to me and ask what is wrong – I use the opportunity to ask them if they were very careful in their technique, if they assure me they were I tell them they should trust their data and try to understand it. It’s fun to have students who think they’re getting poor data get rewarded in the long run with praise for having the most accurate results. (I also give a 5 pt bonus for getting good results and recognizing them.)

AP Biology Syllabus/Schedule

September 8, 2008 in Teaching Resources

I’ve been asked if I would post my AP Biology Syllabus, so for what it’s worth, here it is.  I’m rather detailed in it – it helps the students see where they’re going but more importantly keeps me to the pace I find I need to maintain in order for them to be ready for the test in May (and helps to make up for my poor memory).  By the way, what I’ve attached here is what I call my teacher edition of the syllabus.  It contains details I don’t include in the students’ version - like exactly which essay it is they will be writing and when I plan to order flies, etc.   

AP Biology Syllabus – Teacher Edition

I start out working deeply in the concepts and use the 7th edition of Campbell’s Biology for this.  However, just before the end of the semester as I’m moving into molecular genetics and biotechnology, I switch to Campbell’s Concepts and Connections.  I feel lucky to have access to copies of both books for my students due to the fact that our school separates AP Biology from our dual enrollment College Biology course (AP students still have the option of dual enrollment in addition to taking the AP exam).  Finally as we near the finish line (the AP exam) in late April, I switch to Cliff’s AP Biology exam prep book, which we cover in its entirety.  This helps us review and fill in a few gaps. 
You will note we generally do quizzes and exams on weekends via Blackboard.  I do this to free class time for learning.  I also usually schedule 6-8 lab sessions on weekends through the year.  Anyone who wants to know more about either of these can feel free to contact me – via this blog or directly via my email listed on the syllabus. 

As you all know, the challenge with AP is teaching the students enough material while at the same time doing enough labs and critical thinking activities to help them build the confidence, skills, and knowledge to be successful on the exam.  I also want to do this while nurturing their love of biology.  Putting them under so much pressure that they leave hating biology or science would be a huge failure in my mind.  This is my ninth year teaching AP Biology and I’ve been a reader of the exams the last two years.  My students have very good success on the exams (usually averaging around 4 with ALL students in the class taking the exam) but I’m always tweaking my schedule and approach, striving to maintain and improve.

Periodic Table of Life’s Molecules?

Something to think about as you move through introductory biochemistry in your bio classes this fall. Here’s a blog post from Thomas Joseph about a letter of correspondence that recently appeared in Nature Cell Biology:
