In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

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

Learners will build and experiment with their own windmills made from simple household materials.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.
