Curated OER
Radiochemistry
In this radiochemistry instructional activity, students read about how scientists learn more about elements using radioactive isotopes. Students answer three critical thinking questions about the reading and radiochemistry.
Curated OER
Water: Where in the Watershed?
Students become connected to their watershed by exploring a local water body and mapping its features. They focus on how the local watershed fits into the larger scheme of the watershed.
