“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this activity, learners will play a coin toss game where the highest total wins. Combine coin recognition, addition, and probability with a game learners can play on their own.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

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

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

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

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

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.
