In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In two separate bags, learners mix water with Epsom salts and detergent.

In this math lesson, learners explore and investigate measurement using standard and non-standard units.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys
