In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

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.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity about human anatomy (page 16 of PDF), learners construct a model arm and discover how muscles and bones work together to achieve efficient movement.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

This activity (on pages 21-32 of PDF) has learners act out several classic brain teasers.

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.
