Pendulums
First-time physicists experiment with pendulums in this physics lesson. They vary the weight of the bob, record how long each takes to complete ten period swings, and then calculate the time for one period. They repeat the procedure,...
Curated OER
Comparing Mitosis with Meiosis
Life science learners view an online animated mini textbook comparing two types of cell division. Working in groups, they use a digital microscope to capture images of cells in different stages of mitosis and meiosis. Then they create an...

The Energy of Evaporation
Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...
American Chemical Society
Exothermic, Endothermic, and Chemical Change
Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...
Cornell University
Exploring Rocks and Minerals
Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...
