In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

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

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

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 design, build, and test models of "dragon boats" made from up to three milk cartons.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

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