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

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

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.

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

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

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

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

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

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.

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

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

Learners build simple catapults and use them to launch cotton balls.

Learners construct and launch paper helicopters.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.
