Students will be able to describe each state of matter in terms of its molecular structure.


(5 minutes)
  • Tell students that they are going to learn about solids, liquids, and gases, or states of matter.
  • Ask students if they know what a molecule is.
  • Explain that a molecule is the smallest amount of something and that molecules are so small that they can't even be seen with eyes! Tell your students that everything is made up of molecules.
  • Tell students that the way molecules move within an object or substance determines whether it is a solid, liquid, or gas.
