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

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

Did you know that a Slinky makes a handy model of earthquake waves?

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

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

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.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

In this weather-related activity, learners make a portable cloud in a bottle.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
