Middle schoolers formulate hypotheses on wave behavior and test them. In this physics instructional activity, students compare and contrast transverse and compression waves. They determine the wavelength of transverse waves.

Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...
