Sam and Annie find a box of marbles in their dad’s closet. Sam claims that the marbles can be used to model the structure of a solid.

Question

Select two statements that best support Sam’s claim.
A.
Marbles in a box touch each other but do not move past one another.
B.
The movements of the marbles in a box are synchronized and orderly.
C.
The marbles have a strong attraction to each other and tend to stick together when they collide.
D.
The marbles in a box appear to move but they remain in a fixed position.
E.
The marbles’ movements are large, random and chaotic.

Answer 1

To support Sam's claim that the marbles can model the structure of a solid, the two best statements are:

A. Marbles in a box touch each other but do not move past one another. D. The marbles in a box appear to move but they remain in a fixed position.

These statements highlight the characteristics of solids, where particles are closely packed and have limited movement, which can be modeled by the behavior of the marbles in the box.
