The Story of How the Moon Was Formed

~60 min · 15 stations

The Story of How the Moon Was Formed is a self-paced learning path in Earth Sciences & Geography, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify conditions during the formation of the early solar system; describe the state of the proto-Earth before the giant impact; examine the evidence for the giant impact theory.
