Students design and create their own air-powered rockets, in this hands-on activity.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.
