In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

En esta actividad la tira cómica muestra a los participantes como pueden hacer un experimento simple para ver cuales líquidos son ácidos.

In this activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

In this activity, learners use simple materials to build their own compass.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

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.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.
