In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this astronomy activity, learners create a model of the solar system using beads and string.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

This game presents you with several different choices you can make in the course of your everyday life to increase your level of physical activity and be healthier.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners construct a rocket from a balloon propelled along a guide string.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners examine nanoscale structures of common things.

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

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.
