Tessa is making a model of the sun, Earth, and the moon. She uses  a pumpkin to represent the sun, an orange to represent Earth, and a blueberry to represent the moon. She places these three items on a poster board. Tessa labels each item. Then she draws the orbital path of Earth around the sun and of the moon around Earth.

What is a limitation of this model? 

• 1. The orange and blueberry are not the right colors for Earth and the moon.

• 1. The model is too small to use real distances between the sun, Earth, and the moon.

• 1. Tessa should have used a basketball, a tennis ball, and a marble for her model.

• 1. The difference in size between the pumpkin and the orange is not the same as the difference between the sun and Earth.
