Learners compare and contrast electromagnetic and physical waves. In this wave lesson, students discover that all waves reflect, refract, and diffract energy. Learners work in small groups to experiment with waves and evaluate the type...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.

Students discuss the concept of global warming and view a multimedia clip on the global warming phenomenon. They statistically analyze mean temperature data and compare a given set of data. Data on atmospheric CO2 is done then they...

Students explore vision by experimenting with lenses in equipment. In this optics lesson, students define the different technology that enhances vision such as microscopes, telescopes and cameras. Students experiment with these devices...
