Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

Up close, an array of dots could look random, but take a step back, and an image forms. By tracing over an image, learners can create their own dot based image.

When was the last time you took a really close look at a leaf? In this activity, learners will use leaves and simple materials to make colorful leaf rubbings.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

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

In this activity, learners explore a surprising method for calculating the mathematical constant pi, known as Buffon's Needle.

This demonstration activity models how Venus appears from Earth.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.
