In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity, learners use simple materials to create giant bubbles.

In this hands-on botany activity, learners sprout vegetables in film canisters.

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 fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

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.

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

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.
