In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners investigate passive solar building design with a focus solely on heating.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
