In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

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

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

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 will explore how and why weight distribution works.

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

In this design challenge, learners will use computational thinking to design their own board game.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

This magic trick is based on how computers detect and correct data errors.

In this activity, learners will write a secret message that only their friends will be able to read.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta o en línea.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.

In this activity, learners will explore their center of gravity.

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.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?
