Trey was asked to build a working model of a landform for a science project. He chose to build a model of a volcano.
Trey formed a base out of clay and then painted the model so it resembled a cinder cone volcano.
Finally, Trey mixed baking soda, vinegar, and red food coloring in the base, so it mimicked lava flowing out of the volcano. Once
he was finished with his project, Trey's teacher asked how useful his model was.
What factor best determines the usefulness of the model?
A. how closely the model's color matches the real world
how closely the model's behavior matches the real world
C. how closely the model's size matches the real world
how closely the model's composition matches the real world
B.
