If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

In this activity, learners control the (apparent) size of a hole with their brain.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

Do grapes, yes the grapes from the grocery store, move in the presence of a very strong magnet?

This Exploratorium activity explores size and scale. Through four levels of screen sizes, learners can sort out objects of different sizes.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

Spin a short piece of PVC pipe that's been marked up, and watch a triangle appear. Enjoy this optical illusion from the Exploratorium's Science Snack series.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

With three cans and some tape, make a drum that you bonk down on any surface to produce a variety of sounds. This activity also teaches you about pitch, vibration, and frequency.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

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.
