Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

This guide outlines how to plant a garden even if you don't have a yard!

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

This activity is on page 8 of the pdf, part of the Sea Life Discovery Box. This is an activity exploring the characteristics of fish.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners design their own experiment to investigate how pollution diffuses through ground material.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.
