You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...

Earth is 149,600,000 km, or 92,957,130.4 miles, from the sun. Young astronauts create an interactive model to learn the distances between planets. Nine groups, each representing a different planet, are spread around at class-calculated...

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.
