A student made a model of how the Earth, Moon, and Sun orbit. She used tennis balls to represent each one. She painted each one a different color. Then, she placed the Moon and Earth close together and the Sun much farther away. What is one limitation of the student's model?

• A. She used the same size balls.

• D. She did not put the Earth in the middle of the solar system.

Which of the following is an accurate model of how the Sun, Earth, and Moon move?

• Diagram F

• Diagram H

• Diagram G

• Diagram J

The model below represents the Sun, Earth, and Moon. How could the model of the Sun, Earth, and Moon be improved?

• Show that the Moon orbits the Sun

• Show that the Sun orbits the Earth and Moon

• Show that the Earth orbits the Moon and the Sun orbits the Earth

• Show that the Earth orbits the Sun and the Moon orbits the Earth

The model below was created by a student to show the positions of the Sun, Earth, and Moon. How could the student improve the model?

• The Sun should be closer to the Moon.

• The Moon should be close to the Earth.

• The Moon should be placed under the Sun.

• The Sun and Earth should be very close together.

A student drew a model of the Sun, the Earth, and the Moon. What change should be made to make the model more accurate?

• Nothing should be changed.
