Implementation Overview:
This exercise on Land Hermit Crabs was designed to last about a week and can be used on an integrated unit on pets or animals. The activities contained within focus on reading and writing within a Science curriculum. Ideally, the students should be able to work in small groups of three or four. Each group will have a different animal to research. At the end of the week, each group will present their findings and a class vote will be taken to decide which pet will be adopted.
Materials needed:
- Computers with Internet access. One computer per group of students is optimum.
- Various instruments to record information, such as pen and paper.
- Supplemental information sources, as indicated below:
