This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

What's a more compelling problem to solve than being stranded on a deserted island?

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this activity, learners will build an air cannon out of simple materials you can find around the house. Although air is invisible to the eye, it is not by any means empty space!
