In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

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

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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 explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

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 (at least three) work together to explore the effects of atmospheric pressure.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

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 calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

This is an activity to do when there is a solar eclipse!

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

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 activity, learners model hot spot island formation, orientation and progression with condiments.
