Understanding how the Moon formed supports understanding of Earth’s formation and early history. The Moon Model-Evidence Link (MEL) diagram is an activity that has students weighing the connections between four lines of evidence and two different models explaining the Moon’s formation—capture theory and giant impact theory. By evaluating alternative models, students can improve upon their scientific literacy and understanding of scientific practices. Suggestions from classroom use of the Moon MEL will help teachers use this activity in a productive manner.
