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 explore Earth's rotation and the Moon's role in our 24-hour day, using their bodies to explore and model the Earth's daily motions in this kinethetic exploration. They relate the motion of the Earth about its axis (rotation) to the... (View More) appearance of the sky over the course of the day. Learners consider the role of the Moon in slowing Earth's rotation over time; if the Moon didn't exist, Earth might be spinning more quickly, giving us an eight-hour day!

Learners create edible models of the interior composition of the Earth and Moon. Common food items are used to construct the cores, mantles, and crusts of both planetary objects. They then compare their structure as they are eating their models.... (View More) This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries.

Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and... (View More) in orbit around the Sun (revolution) is related to the appearance of the sky over the course of the day and year. Next they model that if the Earth's tilt was not stabilized by Moon, Earth's axis would slowly wobble between straight up (0° tilt) to nearly on its side (80° tilt). The resulting seasonal extremes would be unfavorable for life. Note that this activity is appropriate for children who are able to explore the geometry of Sun-Earth-Moon relationships in three dimensions. This activity is part of Explore!

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!
