In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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 (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners investigate how geometry plays a role in perspective.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this activity, learners use candy pieces and a cookie to make an accurate model of the Sun they can eat. Parts of the delicious model include solar granules, sunspots, and solar prominences.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

This activity introduces learners to the structure and properties of carbon nanotubes.
