In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

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

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

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

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

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 activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

Learners act as engineers and design mini submarines that move in the water like real submarines.
