In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners perform a simulated blood test procedure.

Visitors observe a tray holding a crystal-covered brick. The crystals were created by evaporation of a solution containing liquid bluing, ammonia, and salt.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

Use multiplication to help the aliens find out how much fuel they need to get their spacecrafts home.

In this activity, learners examine nanoscale structures of common things.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.
