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

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 activity, learners explore how composites work by creating and testing their own composite for an imaginary company.

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.

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

In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

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

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.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

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 are asked to examine the differences between two materials in a pair.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

We don't normally view people upside down and so our brains aren't accustomed to it.

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!
