In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

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

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

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, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.
