In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners examine antibodies and antibody recognition using a model.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

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 mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

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

In this activity, learners explore sports engineering and advanced materials development.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.
