Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

The demonstration/experiment provides quick proof that air has mass.

Learners will understand the relationship between climate change and sea-level rise.

Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.

This magic trick is based on how computers detect and correct data errors.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

Learners play the role of materials engineers as they test the flexibility of different materials.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
