Question

How would you describe (explain the differences) solids, liquids, and gases to a 4th grader? Be clear please.

Answer 1

A liquid is something like water. A gas is something like gasoline a solid is something like a brick

Answer 2

A solid is an object that has definite shape, volume, and mass. This means that the shape, volume, and mass will never change.

A liquid is something that has definite volume and mass, but it does not have definite shape because a liquid is the shape of its container.

A gas does not have a definite shape, mass, or volume because a gas is able to spread around.
