HS-ESS1-6: Earth's Place in the Universe
- Apply scientific reasoning and evidence from ancient Earth materials, meteorites, and other planetary surfaces to construct an account of Earth's formation and early history.
Model A: The Moon was an object that came from elsewhere in the solar system and was captured by Earth's gravity.
Model B: The Moon formed after a large object collided with Earth and material from both combined to create the moon.

Lines of Evidence
Evidence #1: Earth's average density is higher than the Moon's.
Evidence #2: Simulations of other star systems show that planets form when smaller objects collide.
Evidence #3: The Moon's orbit around Earth is tilted compared to Earth's orbit around the Sun.
Evidence #4: The composition of Earth and the Moon is similar near their surfaces. Their cores are different.

The Google Drive folder below contains MEL resource documents in the Google formats. In order to maximize the flexibility of our activities, the MEL Project Team wanted to make more resources compatible with virtual settings. We have made our MEL scaffolds available in Google formats, so that they can be copied, modified, and uploaded more easily on a variety of platforms and devices. Please note that to access all the materials for each MEL scaffold, you will need a Google account. View the README file first.
