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

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

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners use sieves with different-sized holes to sort balls by size.

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, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

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.

In this activity, learners will explore ways static electricity interacts with the surroundings of an object. The activity has step-by-step instructions in English and Navajo.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this activity, learners examine nanoscale structures of common things.

In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

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

In this activity, learners investigate how some butterfly wings get their color.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'
