Question

1. A student represented a water molecule using beads and straws. She connected two black beads and one white bead in a certain manner using straws. Which of the following explains the type of scientific model created by the student?
A. A simulation because it helps visualize the shape of the molecule.
B. A 3-dimensional model because it helps visualize the shape of the molecule.
C. A simulation because it helps understand the movement of atoms in the molecule.
D. A 3-dimensional model because it helps understand the movement of atoms in the molecule.

Answer 1

Hello! Your answer is (B. A 3-dimensional model because it helps visualize the shape of the molecule.) This is because the model they are creating is not a simulation. Also, it can help us visualize the shape of the molecule due to the manner in which it was formed.

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

When the student is using beads then he is representing atoms and the straws represent the bond between the atoms.

Therefore, when a model is represented by the given manner then it helps in identifying the geometry or shape of the object. This is because it shows how atoms are arranged in space along with their angle.

Therefore, we can conclude that out of the given options the type of scientific model created by the student is a 3-dimensional model because it helps visualize the shape of the molecule.
