This lesson is designed to: Review the definition of matter. Review the physical properties of matter
and how we use our senses to describe them.
Discuss how certain properties help us to sort matter into categories or states of matter.
Matter:
It’s what the world is made of.
What is matter?
• Everything in our universe is made of matter.
• All matter takes up space and has weight.
• There are 3 basic states of matter: Solid, liquid, Gas
What do you know about matter?
Liquids
GasesSolids
But what is the difference between a solid, a liquid, or a gas?
Solids
Solids hold their own shape.
Solids have weight.
Solids take up space.
Liquids Liquids take the
shape of their container.
Liquids have weight.
Liquids take up space.
Gases
Gases spread out to fill the entire space given.
Gases have weight.
Gases take up space.
STATES of matter?
What would it take for matter to move from one state to another?
Energy determines the state!
Solid
+ Energy =
Liquid
+ Energy =
Gas
All matter is made of molecules…
This is one water molecule (H2O)…
This is two H2Omolecules…
Molecules in Solids: Are packed tightly
together Molecules only have
space to vibrate. Have very little
energy
Molecules in Liquids: Are loosely
packed Molecules flow
freely Have medium
energy levels
Molecules in Gases: Move freely Molecules shoot
every direction Have LOTS of
energy
Add or subtract energy, and matter changes state!
What will happen when we add the energy from the sun?
