This is an activity about the rotation of the Moon. Learners use a penny and a quarter to model that the Moon does indeed spin on its axis as it orbits the Earth. They find that the Moon keeps the same face toward the Earth, but receives... (View More) illumination from the Sun on all sides in turn. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)
Learners model how the Moon's volcanic period reshaped its earlier features. The children consider that the broad, shallow impact basins contained cracks through which magma seeped up. A plate in which slits have been cut is used to represent an... (View More) impact basin and a dish of red-colored water is used to represent the pockets of magma within the Moon's upper layers. When the model impact basin is pressed into the "magma," "lava" fills in the low areas through the same process that produced the dark patches, or maria, on the Moon. Children may examine a type of Earth rock (named basalt) that is also found on the Moon and that would have been shaped by the processes explored here. This station investigates the Moon's "teen years," when it was one to three billion years old. This activity is part of Explore!
