Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

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.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

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

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

In this activity, learners explore clouds and how they form.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

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