In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

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 two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

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.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

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.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

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

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

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

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

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

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.
