In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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

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 carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

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, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

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

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

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, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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.

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

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this math activity, learners experiment with the concept of symmetry.
