In this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
