3. Question of the Day
At which diagram will Ohio experience the season of Summer?

4. The Earth Moon Sun Relationship Part 1

5. How are the sun, moon, and Earth related?
By their movements.
1. Rotation- the spinning of Earth on its axis
2. Revolution- the movement of the Earth & moon around the sun. the movement of the moon around Earth Explore a model of Earth's daily rotation Explore a model of Earth's yearly revolution around the sun.

6. Spring
Summer
Fall
Winter

7. The Seasons of Earth Q. Why does Earth have different seasons?

11. Skills Lab
Earth experiences changing seasons because of the tilt of Earth’s axis and its revolution.
Objective: Create a model using clay that represents the relationship between the Earth, sun, and the changing seasons.
Procedure:
1. Chose 1 color and create a model of the sun. Remember: The sun is much larger than Earth.
2. a. Use the 2nd color and create 4 models of Earth
b. Take the skewers and insert them through the
Earth’s so that Earth’s axis is tilted roughly at 23°
3. Create a model in which the Earths circle the sun and are in the proper position according to the seasons.
