Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Examine earthquake intensities and ways to measure an earthquake through the comparison of the Mercalli and Richter scales. After completing the pre-lab worksheet, fourth graders compare high and low intensity quakes by testing...

Beer's Law can be used to measure the concentration of certain compounds in samples of food. In the concentration simulation, particpants change and measure the concentration of different solutions by manipulating various types of...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Stars are too hot to visit, so how do we know what different stars are made of? An enlightening simulation uses a spectrum graph to show the various electron emission and absorption reactions. Scholars experiment with both helium and...

Students study definitions of wavelength, wave speed, wave amplitude, and wave period using an interactive JAVA environment. Distance and time are given so speed=wavelength/period can be verified or deduced by students. Waves reflection...

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

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Make sound waves visible with an experiment that asks middle schoolers to build a model ear drum using plastic bottles, rubber bands, plastic wrap, and sand-like substances.

Students view a variety of scientific images and animations. They explore the world of science and visual art. Students enrich their knowledge through animation examinations of thoughts and feelings and awesome color rainbows of...
