This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

Play with a slinky and make transverse waves. In this simple Exploratorium Science Snack, learners will experience making waves and will learn the different parts of a wave.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this activity, learners discover how hard their hearts work to pump blood.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this online game, learners must keep their snowboarding racer in the middle of the course without veering off track or hitting obstacles.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

This website contains several activities. Mixing in Math Moments are activities that take 5-10 minutes that keep learners occupied, learning about the world, and using math on their own.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

We don't normally view people upside down and so our brains aren't accustomed to it.

Known as the waterfall effect, this activity demonstrates adaptation in our visual system.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this activity, learners play a game similar to Tic-Tac-Toe. In this version, learners try NOT to get three-in-a-row. The player who gets three-in-a-row first loses!

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.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

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 physics activity, challenge learners to remove the bottom coin of a stack of nickels without knocking over the stack. Use this activity to demonstrate friction.
