Changing Planet: Withering Plants - Stressing Over Lost Water
Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...
Curated OER
Cell Division
Students describe the cell cycle. They make a connection between DNA replication and cell division. Students describe the parts of the cell that participate in cell division and the steps of cell division.

Life in Extreme Environments - Lakes Under Ice
High schoolers collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess...
Curated OER
Investigation of Meiosis in Common Plants and Animals
Students witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.
