SOLIDS, AND LIQUIDS, AND GASES, OH MY!

Today we learned about the properties of solids, liquids, and gases.  We compared the three and learned about their molecular structure using cheerios as a model!

SOLID

Has a definite shape and volume.  In other words, a solid has a shape that doesn't change unless acted upon and does not flow.

LIQUID

Takes the shape of its container, but has a definite volume. In other words, a liquid flows and does not have it's own shape.

GAS

Fills the entire volume of its container. In other words, gases are free to fill whatever space they have.  You can't always see them. 

Solid  molecules are close together and do not move past each other.

Liquid molecules are close together, but slide freely past each other.

Gas molecules move freely past each other quickly and don't stay together
