Modeling the Moon

Activity Description: Students will develop and use a model of the Earth, sun and moon system. 

Materials Needed: Light source  (a light bulb in a socket able to stand alone) several white, styrofoam balls or light colored play balls.

Prior to Assessment: Students should know that the moon revolves around Earth and Earth revolves around the sun.  They should be familiar with the fact that we see the moon best at night but we can see it during the day.  They should also know that it is always half lit by the sun but we cannot see the entire lit half except during a full moon.

Time Needed for Assessment: One hour

Procedure:

1. Divide the class into groups of four or five students.  Each group need a moon (ball)

2.  Explain to students that the light source represents the sun, the ball is the moon and one of their heads will be Earth.  The head can rotate just as Earth does. 

3.  One student from each group should volunteer to be Earth and one will hold the moon ball. 

4.  Darken the room as much as possible and turn on the "sun".

5.  Start with "Earth" facing away from the "sun" and the moon ball on the side furthest from the light source.  This would be a full moon to the Earth observer.

6.  Other students in the group need to follow the directions on the worksheet and ask their Earth and moon to move around.  At each position the questions should be answered.

7.  When the students have had time to learn from their model, ask each group to position themselves in a particular phase of the moon. 

Scoring guide:

1.  Students model the phases and work in their groups................................5 pts

2.  Students accurately fill out worksheet and answer questions...................5 pts

3.  Students are able to correctly model phases when asked........................3 pts

Student Worksheet:

Use this diagram of the phases of the moon to help you with your model.

 1.  Start with the moon on the far side of Earth from the sun.  Have the person who is "Earth" describe what the moon looks like.  Draw it here:

What is the name of this phase?

2.  Have the person holding the moon move around the Earth a little way. Draw the moon as it is described by "Earth".

What is the name of this phase?

3.  The moon should continue around Earth, each time make a drawing and label the phase.

4.  Your teacher will ask you to model a phase of the moon.  Be ready to show how that phase will look.
