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.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

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

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners explore how salt water freezes in comparison to fresh water.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
