Math Is Malleable?
Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...
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
Gases
In this gases worksheet, students review the kinetic molecular theory and use the ideal gas law to solve 20 problems.
