Feedback from trial session
Thanks for your analysis ideas.
Thanks Alison You are welcome of course! Thanks for the input. I used your suggestions to improve things and presented it all at the ABLE conference (Bio Lab Educators). I had the educators at the meeting make measurements from a sample of the largest NE and largest NW skulls and take it from measurement through stats (aimed at upper level college). We did on paper measurements or used ImageJ. If you print the ruler with each skull you can use the paper ruler to measure things (only for the skull that the ruler came with).
Here is the sample we worked with: http://wikieducator.org/NE_NW_skull_comparison Might be better for high school to start with a question where you already know the answer? NE>NW
I just read that coyotes from NW have shorter snouts....something for my Evolution kids in Spring to investigate. I expanded my Alaska and Texas collections so if there's a difference we'll find it
Great idea to pick out sample with a known result, that we could work on from measuring through to statistical comparison. I have two kids in both my biology and statistics classes, so I'm hopeful that they'll be interested to follow through with the whole process. I'll definitely use the selected sample. We'll be tackling this in May or so. I'll check back here with how we make out.
