In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

In this activity, learners build water-propelled engines from soft drink cans.

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 activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

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

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
