How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...

A colorful and comprehensive PowerPoint highlights this lesson on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how compact discs work...

Don't string your class along! Physics scholars discover the fascinating forces behind the music of stringed instruments using an interactive. From a series covering sounds and waves, the interactive asks users to identify nodes and...

Ever wonder what really goes on inside a clarinet? Show your young scientists the physics of open-end air columns through an easy-to-use interactive. Learners examine the features of standing waves and calculate frequency and length in a...

Radio waves are all around us! How do they transmit sound? Using an interactive, scholars examine how songs travel through the air. The resource explains the process from the radio station, to signal towers, to the radio unit. A look at...

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 program to make an automated vehicle perform a specific task. In this robotics instructional activity, students play the role of scientists competing to win a factory's contract. They present their algorithm to class.

Students enter the gym. Teacher hands out the 3 animals to 3 different students. They with the animals are the taggers. One at a time, each tagger calls out a different locomotor movement to travel in (preferably running is NOT a choice).

Students participate in a role play in which they use simple machines to do the work of retrieving their sibling from a tree which lost its ladder. They investigate how work is accomplished when an object moves in the direction of the...

Students use their imagination. They discuss the 4 C's of teamwork: Concentration, Communications, Coomperation, and Consideration. Students discuss the safety guidelines of the project. They complete a rope maze. The group walks...
