Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

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.

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

Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

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.

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 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!

This is an activity about center of gravity. Learners will balance a fork on a glass by finding its center of gravity.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

In this activity, learners mix white craft glue and borax solution together to produce a surprising new material: GOOP!

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.

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.

In this activity, learners will investigate static electricity as they create waterless snow globes.

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

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

Can you think of ways to collect and dispose of spilled oil without causing further harm to the environment?
