In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, learners explore Charles' Law in a syringe.

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

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

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 math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.
