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

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

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.

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

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 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.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

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.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

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

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

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 activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners will explore the water cycle by creating a small atmosphere.
