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.

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 eat a snack and make a model of the plumbing system of a volcano.

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.

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

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

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

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

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

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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, learners create a model using metric measuring tapes and atmosphere composition data.

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