The world's largest measured earthquake happened in 1960 in Chile, reaching a terrifying 9.5 magnitude on the Richter Scale. The second lesson in the 20-part series introduces earthquakes and fault lines. Scholars map where previous...

The Sierra Mountains in Nevada and the Tetons in Wyoming originally formed as fault block mountains. In order to visualize these fault blocks, pupils use construction paper to create layers of earth. They cut the paper models and form...

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...

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

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...

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...

Don't be caught in the dark! Young scientists investigate the causes of both solar and lunar eclipses using an interactive to help them understand the development of an eclipse over time. They then research facts and characteristics...

Don't get your classes all shook up about plate movement, instead use a thorough unit that guides learners to an understanding of plate tectonics. The lessons incorporate a study of the types of plate boundaries and their effects on the...
