In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

In this activity, learners construct a device that allows them to look over ledges or around corners.
