Radiation and Color
Tenth graders explore the relationship between color and heat absorption by measuring the temperature change of water in differently colored test tubes as they are exposed to a heat lamp. They work in small groups to collect data and...
Curated OER
Ecological Succession in Pond Water Cultures
Students collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.
Curated OER
Designing an Earthquake-resistant Structure
Students attempt to design and build the most stable "earthquke resistant" structure. They create model buildings and test them on a shake table to see which design holds up the best.
Curated OER
Is a Pulley a Special Kind of Lever?
Fifth graders use information from their text to read and discuss pulleys and levers. They examine a top sketch of the arrangement of a fixed pulley. Working in groups, 5th graders perform experiments to test the effect of using a pulley...
