Nature Study Lesson 59: The Bat and Mammals

We first discussed the characteristics of mammals and then we looked at bats in particular. Although lesson 59 suggests that the teacher temporarily keep a bat in the classroom in a cage, I didn't think that this was feasible for us, so we made as many observations as we could using photographs and observations of naturally flying bats outside. They made sketches and noted their observations in their notebooks.
They all know the Magic School Bus: Going Batty video and this has a lot of information about bats in it as well.
