SOLVED: Determine 1 the diagram represent a chemical or physical change? Explain your answer. Does the following diagram represent a chemical or physical change? Is helium a solid, liquid or a gas? The particle model of matter requires that particles remain the same size no matter what.

Print the student activity sheet and distribute one per student when specified in the activity.
Sheet of colored paper or construction paper.
