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...

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

Students explore musical pitch. In this cross curriculum musical instruments and "sound" physics lesson, students identify and describe common traits of woodwind instruments. Students research "pitch" and what causes pitch fluctuation by...

Students identify the different parts of a wave. In this physics lesson, students explain how animals communicate using sound waves. They discuss the effect of Navy's sonar on dolphins and whales.

Students design a storage facility that can withstand extreme wind loads. In this physics lesson, students decide how to build their facility considering budget constraints. They evaluate their design and present it to class.

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.

Students investigate the different methods used in integrated pest management. In this biology lesson, students evaluate experiments and case studies on IPM. They discuss the pros and cons of using this method.
