This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

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

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

“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 engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this lab (Activity #1 on page), learners explore how we see color.

This is an online activity about what would happen if we could travel at or near the speed of light.

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

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

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.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
