Activity Prep

Print Prep

This lesson explores why the Moon seems to change shape (phases) over the course of a month. In the activity, Model the Moon's Phases, students use a styrofoam ball as a model of the Moon and a flashlight as a model of the Sun to gain a better understanding of how the interactions between the Sun and Moon are responsible for the Moon’s phases.

Preview activity
Number of students:

I have a Mystery Pack

Pencil
Sharpened. Skewers also work.
Details
1 pencil per pair
Bright Flashlights
You can also use a bright lamp or overhead projector that you can point towards the students to serve as the Sun for multiple groups. Be careful not to look directly into such a bright light source.
Details
1 flashlight per pair
Styrofoam Balls (2")
We suggest smooth, solid styrofoam balls. Rough foam balls are translucent and don't work as well. You can substitute any round opaque object that can be skewered.
Details
1 ball per pair
Prep Instructions

We suggest students work in pairs. Homeschool students will need a partner for this activity.

Prepare to Darken the Room

It is important to get your room as dark as possible! It's worth taking the time to black out your windows and even tape curtains to eliminate cracks of light. Also, the brighter your flashlights, the better the demonstration. The flashlights we link to are particularly bright and inexpensive.
