12.

A student made a model of how the planets orbit the sun. She used a tennis ball to represent the sun. She used ping-pong balls to represent each planet and painted each one a different color. Then, she placed all the ping-pong balls equal distances apart in a line extending out from the sun.


What are two limitations of the student's model? (Limitations are things about the model that limit its accuracy.)

a)

She used the same size balls to represent the planets.

b)

She made planets orbit the sun.

c)

The planets are not the correct distances from the sun.

d)

The solar system can't be modeled using actual objects.

13.
