In this activity, learners explore probability with dice.

Jugando a este juego, los chicos desarrollan habilidades de lógica, geometría, y visualización espacial. Los jugadores empiezan con una red de hexágonos vacía.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners watch a figure "magically" float up through the air.

In this activity, learners will investigate the sounds of the heart.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity on page 6 of the PDF, learners use glue instead of glass to create artwork that can be hung in a window.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners will explore how computers represent pictures using pixels.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

This activity provides step-by-step instructions on how to build a rain stick, a musical instrument originating in South America.
