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.

Here's a topic classes can really dig—the fossil record. Use the well-organized and thoughtful road map to take eighth graders back in time to unearth the answer. Learn how our climate has changed, and how organisms have...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Young scholars calculate the escape velocity of planets in our solar system and use that knowledge to calculate the escape velocity for NGC 2300 group. They then suggest reasons for the escape velocity to be higher than possible given...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...
