Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners explore rocketry and the principals of space flight.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
