When you go outside at night sometimes you can see the moon. It looks different at different times. Sometimes it looks like a sliver.  Sometimes it looks like a half circle, and sometimes it looks like a ball.  What shape is it really?
 
The Earth and moon are spheres. A sphere is a rounded solid shape – like a ball.

Draw spheres!

  1. Start with a circle.
  2. Carefully shade around the edges as shown. This will help your circle look 3D.
  3. Draw six spheres. Turn each into something different. Be sure to turn one into the Earth and one into the moon!
  4. Share your super spheres with someone special!
 
Can you combine your spheres to make something fun?
