STUDENT ACTION AND INVOLVEMENT

Students discuss the benefits of using solar energy. In this earth science lesson, students select a solar project they want to work on. They prepare a presentation and share this with the class.

How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 series, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...

Computer-interfaced motion detectors are required to carry out this inquiry. It is a new twist on exploring motion with plunger carts: they are set back-to-back and then propelled away from each other. Their velocities are measured, and...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

Student's attention is focused on the environment during Earth Day. This helps to stimulate their creativity and imagination, so that they can act persuasively to help solve environmental problems.

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Students analyze information to determine how they can help a community that has been affected by water contamination.  In this environmental science lesson, students watch portions of the movie "A Civil Action" and discuss specific...

Students work with models of substrates and of enzymes and test the digestion of lactose with lactase. They determine if digestion of lactose has or has not occurred.

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

Students observe cytoplasmic streaming in Nitella cells. They examine the conduction of a wave of depolarization across other membranes, such as the axons of neurons. Students predict the effects of sending a small electric current...
