Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

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 determine the necessary conditions for pea seed germination.

In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
