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

In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, you'll use a paper cup, a piece of cloth, and some string to make a musical instrument called a cuica (pronounced KWEE-kah).

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

This activity is an investigation of static electricity. What happens when you get "static cling?" Basically, you pile up electrons on one thing, which attracts the protons in something else.

In this quick and easy activity, learners build an air cannon "drum" and see what happens when they "shoot" puffs of air at different targets.

This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.

This is an activity about center of gravity. Learners will balance a fork on a glass by finding its center of gravity.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!
