Instead of dissecting a real frog, the students worked on a 3D frog paper dissection model from Getting Nerdy with Mel and Gerdy. There are a lot of parts to this model, the list of organs and body parts to color is 4 pages long! Most of the students barely finished the coloring, so we’l finish them up in class next week. While students were coloring, I read the information pages on frogs and their anatomy.
I also have a plastic simulated frog dissection kit that came with a plastic set of organs and a squishy set – though it looks like it only comes with plastic ones now. You can see it in the middle of the table in the photo below.
Over the last month I’ve also been raising painted lady butterflies (Insect Lore) and we released them this week. The tiny caterpillars arrive in a small plastic cup with food in the bottom. It takes a few hours/days for them to start moving around but they grow quite fast.
In just a few days they had doubled in size.
The cup came with 6 caterpillars and after a week I opened up the cup and put in the butterfly habitat with some branches so they could stretch their legs. It wasn’t long before they made for the top of the habitat, hung upside down and formed chrysalides (about 10 days after they arrived).
10 days later butterflies emerged from the chrysalides. I kept them in the habitat (fed them diluted sugar water) until all my students had seen them and then we released them outside.
If you haven’t raised butterflies from caterpillars before I highly recommend it, especially for elementary students.
