In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

Learners use Duplo bricks to build antibodies with shapes that match model viruses.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
