Third-grade students investigate roly-polies to learn about ecosystems.
This amazing article turned common pill bugs (roly-polies) into a wonderful study of the ecology (examining how organisms interact with their environment, including other organisms) of the pill bugs. One thing I had never seen before was a choice chamber where the pill bugs had a chance to decide which habitat they preferred. This article goes into great detail on the experiments done by the students. What a simple way to study animal behaviors!!
