Measure the human pulse by counting the movements of a drinking straw attached with clay to the pulse point on the neck. Predict activities that affect pulse rate, and compare your pulse with another person's.

A cross curricular unit where learners simulate an energy task meeting to discuss protecting human health through energy policies. The unit covers content for twelfth grade in math, physics, language arts, and government. Topics reviewed...

The animation portrays a medium as a series of particles connected by springs. In this type of longitudinal wave the particles of the medium vibrate in a direction parallel to the direction of energy transport.

A reference page that explores boundary behavior of waves with an animation and examples.

This lesson focuses on Maya Angelou and her poem "On the Pulse of Morning." It features links to Angelou's biography, her official website, National Women's Hall of Fame, and her poem "On the Pulse of Morning" in text and in audio.

Explore an active area of research in optical physics: producing designer pulse shapes to achieve specific purposes, such as breaking apart a molecule.

In this simulation, two strings with different densities are held tautly as a wave pulses along them. Variables can be changed to alter the relative densities of the strings, as well as the type of wave pulse.

A cross curricular unit focusing on how much and what kinds of foods are produced because of pesticides and genetically engineered foods. Students will investigate the impact on humans due to the new technology in food production. Topics...
