This is a simple and fun activity for learners to explore water and colors.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Did you know that a Slinky makes a handy model of earthquake waves?

In this sensory activity, learners enjoy the fun of a snow day any season of the year.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, learners create and understand surface currents. Learners create example surface currents and discover how landmasses affect the current.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

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

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.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
