The Moon MEL
Below are links to resources that will help students use the Moon MEL and learn more about fundamental scientific principles related to the Moon and its formation.
This article provides an introduction to the Moon MEL plus suggestions from classroom use including management tips, potential problems, and activity extensions.Understanding Formation of Earth's Moon TES (Acrobat (PDF) 822kB Jun4 18)
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. The density of Earth's crust is a little less than the Moon's, but Earth's density increases toward the core.
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 the planets' orbits around the Sun.
Evidence #4: Earth is about 35% iron, most of which is in the core. The Moon has very little iron.

This Plausibility Ranking Task (PRT), which may be completed prior to using any MELs, helps students to understand the role of evidence in supporting or refuting models.

The Explanation Task is part of each MEL Activity. In this task, students provide written explanations for the arrows they draw on the diagram. The following rubric may be used to score students' written explanations.
