Yesterday we did another one of my favorite "labs" in biology. The students had just read the mitosis and cell cycle chapter. To review the events of mitosis, we do an activity I found on Amy Balling's blog, Ballin with Balling. She talked about giving her students an engaging activity on the last day before Christmas break. This involved pulling off the tops of double stuffed Oreos and using sprinkles, toothpicks and the cream covered half of the Oreos to model the process of mitosis and cytokinesis.
Her blog post also included a link to the lab sheet she designed to go with the activity. I used her lab sheet, but reformatted it to be only two pages long. Here's the reformatted version.
It has been a big hit with the students both years that I've used it. It's one of the few opportunities that students have to eat their lab.
