I just returned from a 3-day trip to Cornell University in Ithaca, NY in which I attended an ASSET (Advancing Secondary Science Education with Tetrahymena) summer science teacher workshop. I would recommend this experience to all of you who are biology teachers! We got to work in one of the veterinary medicine labs on campus and preview ASSET laboratory modules using the very lab-friendly protist, Tetrahymena. My computer was connected to a microscope camera and then I used my iPhone to videotape my computer screen. This particular clip is from a phagocytosis lab we did with the protist. We fed our Tetrahymena black India ink, took a sample every 10 minutes, placed a drop of each sample on a microscope slide, and counted the number of food vacuoles that had taken up the ink in 10 different organisms. I plan on using this lab and others we were able to sample next year in my biology classes. This set-up with the microscope cameras allows students to collect real data on a living system! Wow!
Here is the website for ASSET: http://assetprod-lamp.cit.cornell.edu/blog/.
They are airing a webcast at 5:45 PM (EDT) on Monday, July 25 of The ASSET 2011 Summer Teachers’ Workshop Panel Discussion if you're interested.
(For some reason I could not get the video to download onto my blog, so I made a screencast of it through screenr and downloaded that!)
