Matter and States of Matter
2 Demos
For each of the two demos, make two observations
and an inference about what is happening (left
page).

Matter is anything that takes up space
Matter is everything around you.
Matter is anything made of atoms and
molecules.
Matter is anything that has mass
MATTER: anything that
has mass and takes up
space
Matter and States of Matter
Matter Anything that has mass and takes up
space
 Matter comes in three main states
(+ two other ones):
 SOLID
 LIQUID
 GAS
Matter and States of Matter
Matter Anything that has mass and takes up
space
States of Solids, liquids, gases
Matter
 What is volume?
 Volume is how much space something
takes up.

Matter Anything that has mass and takes up
space
States of Solids, liquids, gases
Matter
Volume How much space matter takes up
 In your notebook (left):
 Name some things that are solid
 What are some characteristics of
that all solids have?

Have a definite shape and volume
 The particles are tightly packed together in a fixed
position.
 Particles are not free to move very much.
 Particles are moving but because they are so
tight, they seem to vibrate

Matter
Volume How much space matter takes up
Solids Definite shape and volume
-Particles tightly packed (compact)
-Particles moving  creates vibration
 In your notebook (left):
 Name some things that are
liquid
 What are some characteristics of
that all liquids have?

Have a definite volume but not shape
 Can take the shape of the container that holds it.
 Still has the same volume because it takes the
same amount of space.
 Particles close together but are more free to move
in relation to each other.

Liquids Definite volume but not shape
-Particles packed together but can move
around
-Liquids take shape of container
 In your notebook (left):
 Name some things that are
gases
 What are some characteristics of
that all gases have?

Have a NO definite shape or volume
 Particles are farther apart
 Particles move faster and more freely
 Particles tend to expand in all directions
Matter and States of Matter
Liquids Definite volume but not shape
-Particles packed together but can move
around
-Liquids take shape of container
Gases NO definite volume or shape
-Particles are far apart
- Particles move and expand in all
directions
 Take 2 minutes to write a
summary
 Make sure to include the following:
▪ What are the 3 states of matter
▪ What are the particles doing in each
state of matter
