overview: 
This lesson is intended to introduce students to desert ecosystems and how organisms conserve water through an inquiry approach. In the lesson, students will observe a model situation and make inferences about real organisms and their ability to conserve water in a dry environment. Students will develop hypotheses and interpret the results of their observations. Students will measure using a balance, record data, and communicate ideas in a written and oral format. Although this lesson was designed to be implemented during an ecology unit it is also well suited to talk about other concepts such as adaptation, natural selection, and global climate change.
