In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

This is a hands-on activity about the physics of tennis. Learners will discover that physics plays a big part in tennis, no matter what their skill level might be.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

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.
