Phases of the Moonby: Geoff Holt and Nancy W. West

Book ChapterDigital resources are stored online in your NSTA Library.

Every 29.5 days, the Moon’s shape appears to change in a predictable cycle. We call the shapes phases of the Moon. This activity will show how the Moon’s orbit causes the Moon’s phases. Students use Ping-Pong or Styrofoam balls to model the way the Sun illuminates the Moon as the Moon orbits Earth. Then they model the orbit of the Moon around Earth using a painted ball to understand why the Moon shows phases.

What a great resource! Understanding the phases of the moon is always a struggle for my kiddos, and the activities in this book will be so helpful! In particular, I like the partner activity where one student walks around "the moon" and draws the phases as he sees them. Brilliant!

If one is looking for a comprehensive lesson on how to teach about the moon phases, how to access student preconceptions and misconceptions, and how to help students create accurate knowledge about this important topic, look no further than this book chapter. There is plenty of background information for the teacher and great hands-on activities for the students. The materials are simply one bright lamp and extension cord, one Ping-Pong ball per student, safety goggles, a 15-cm Styrofoam ball, black paint for the Styrofoam, a bit of cardboard and a pencil. I highly recommend this lesson plan if you are contemplating teaching about the moon’s phases.
