In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this engineering activity, young learners investigate multi-level buildings.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
