Grade 6 Solids, Liquids and Gases

1. Learning Intention Success Criteria
• Understand what states of matter are.
• Understand what the particles in solid liquids and gases look like.
• Begin to understand the process of changing state.

3.  All matter exist in one of three states: solid, liquids
and gases. Each of these have different
arrangements of particles.

4. 
All matter is made up of tiny particles called
atoms or molecules. Molecules are always
moving. They move differently depending on
whether they are a solid, liquid or gas.
Simulation of the States of Matter
-Practical Activity-
Role modelling the states of matter (in open area)

5.  Solids, liquids and gases are all around us.
Some substances can change from one state
to another when heated or cooled. Water can
change into all three states.
 Demonstration

6.  This diagram
shows that if
you add heat
to a substance,
it can change
its state of
matter.

7.  A substance can change
from a solid to a liquid,
from a liquid to a gas, or
from a liquid to a solid.
 These changes are physical
changes. The substance is
the same, just a different
form, and the process can
be reversed.

8.  Solids and liquids expand when they get hotter
because the particles move further apart.
When they cool, they contract because the
particles become closer together.

9. What are the 3 states of matter? _________, _________ and _________
Fill in the gaps:
__________________ occurs when a solid becomes a liquid.
__________________ occurs when a gas becomes a liquid.
__________________ occurs when a liquid becomes a solid.
___________________occurs when a liquid becomes a gas.
How would you describe the arrangement of particles in a solid?
What are the particles in a liquid able to do that means a liquid can
take on the shape of the container?
