Did you know that you would be a different age if you lived on Mars? It's true!

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners explore their eye pupils and how they change.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

In this activity, learners overlap the three primary colors to see how all other colors are made.

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

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

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.

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 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 create models of ionic compounds and observe the chemical formula of binary molecules they have created.

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

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

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