Science education should start early! And as part of our collaborative NSF grant on milkweed genetics and ecology (with Georg Jander from BTI and Steve Broyles from Suny Cortland), we are implementing outreach projects in the K-12 Ithaca schools. Led by research support specialist, Amy Hastings, and inspired by a set of experiments by former postdoc Patty Jones, second graders are conducting real scientific experiments. In previous work, Patty noticed that monarch butterfly caterpillars much prefer to feed on the swamp milkweed (Asclepias incarnata incarnata) compared to it’s sister species (Asclepias incarnata pulchra). Pulchra has dense hairs which get in the way of feeding and the leaves also appear to be more toxic to monarchs.

Thanks to Amy, Katie Holmes, Jacob Elias, and Lina Arcila-Hernandez for helping to make this happen. And thanks also to the second grade teachers of the Belle Sherman school, and, of course, to our enthusiastic data collectors!
