Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

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

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

Did you know that you would be a different age if you lived on Mars? It's true!

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

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.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

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

In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

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

In this activity, learners make their own "tornado" using two soda bottles and water.
