Biology with third graders

In the past month I have been occasionally visiting local third-grade classes with some colleagues to deliver a lesson on adaptive variation. It isn’t as dry as that makes it sound—there are puzzles and tiny spoons and squishy fishing lures. We are fun scientists. Science is fun! Science is fun but if you don’t put the fishing lures back in the bins and pay attention, we won’t get to start, okay, I know they’re gross, please don’t throw them, thank you, as I was saying, science is fun!

It has been interesting to see how much difference there is between classes. One class squirmed and giggled whenever we suggested that animals might need to find, as we put it, “boyfriends and girlfriends.” Another class was completely unfazed. “Yes,” one student in that class clarified, “they need to find mates.” Every class so far has known about camouflage and what hummingbirds eat.
