In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today. Learners create a simple model of this process by mixing household items of different densities in a bottle and allowing to them to settle into separate layers. Learners decide which materials make the best model for the infant Moon. Learners may examine a type of Earth rock (named anorthosite) that is also found on the Moon and that would have been shaped by the processes explored here.
This activity station is part of a sequence of stations that can be set up to help learners trace the Moon's 4.5-billion-year history from "infancy" to the imagined future. Learners tie together major events in the Moon's geologic history as a series of comic panels in their Marvel Moon comic books.
