En esta actividad, los aprendices usarán la lógica para ganar un juego. Dos personas toman turnos quitando uno o dos "cuerdas" de las estacas en el suelo.

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.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

“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.

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

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 chemistry demonstration, acid rain is simulated in a petri dish.

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.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or
