3rd Grade - Physical Change

During our last meeting, we explored the physical change of matter. Physical Change describes when something changes from:

- a solid to a liquid (popsicle melting)

- a liquid to a solid (making ice cubes)

- a gas to a liquid (condensation on the bathroom mirror)

- a liquid to a gas (puddles evaporating).

Ask your student about the tasty treat that we enjoyed in the lab and what steps we needed to take to make it.

We also discussed how the molecules behave differently in each type of matter.

Ask your student whether molecules in a gas or solid move more quickly.

Bonus question: Ask them why gases are invisible.

Next up, we'll explore Chemical Changes.

Science Rules!
