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

This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

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

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.
