Let's take a look at molecules!

All About LIQUIDS!

Did you know??

-Solids can be hard like a rock, soft like fur, big like an asteroid, or small like grains of sand. Solids can hold their shape because their molecules are tightly packed together.http://www.chem4kids.com/files/matter_solid.html

-Gases can fill a container of any size or shape. The molecules in gases are really spread out, full of energy, and constantly moving around in random ways.

-Liquids fill the shape of any container they are in. If you pour water in a cup, it will fill up the bottom of the cup first and then fill the rest.

All About GASES!

-Many liquids want to stick together because of cohesive (sticky) forces that pull the molecules together.
