In this activity, learners will learn about proprioception, or the body's sense of its place and position in space.

In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

Coins are everyday objects which tell a lot about the people who use them.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.

In this activity, learners will explore density and it's relationship with mass.

In this activity, learners will explore how and why weight distribution works.

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

Learners will collect pennies to donate and will combine charitable giving with estimating and calculating with money. To start choose a charity or something to save up for together.

In this activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.
