1. What is matter?
Matter can be anything that is made of atoms and molecules. Matter consists of any object that
takes up space and has mass.
2. What are the 3 main states of matter?
Solid, Liquid, Gas
3. What are some properties of a solid?
Solids keep their shape. A solid has a definite size and shape. Solids always take up the same
amount of space. Solids can change their shape if you cut them, twist them, or squash them. Solids
have particles that do not flow easily. Solids can be hard and soft.
4. What are some properties of a liquid?
Liquids do not have a definite shape. They take the shape of the container they are in. Liquids have
particles that flow easily and can be poured easily. They are not easy to hold in your hands. Liquids
have the same volume, even when they are poured into containers with different shapes.
5. What are some properties of a gas?
Gas has no shape, size, or color. Its particles flow easily past one another. Gases take the shape and
volume of its container. Gases are invisible.
6. Play the interactive game on the following website. Which objects were solids, liquids, and
gases?
Solids: Ice, Sand, Wood
Liquids: Syrup, Rain, Milk
Gases: Steam, Air, Helium

7. How does matter change from one state to another?
Matter changes states by heating or cooling. When a solid is heated, it changes to a liquid. When a liquid
is heated, it changes to a gas. When a gas is cooled, it changes to a liquid. When a liquid is cooled, it
changes to a solid.
8. Draw or find a picture of what the molecules look like in a solid, liquid, and gas.
9. At which temperatures does water become a solid and a gas?
Water becomes a solid at 0 degrees Celsius. Water becomes a gas at 100 degrees Celsius.
10. What happens to the container if you increase the temperature past the gas state?
The pressure inside the container is increased and the lid is forced off. The steam escaped.

A Weighty Issue: Mass vs. Weight
 MASS





The amount of matter that an object
contains.
Mass is not determined by the size of the
object.
A large beach ball does not contain more
mass than a small baseball.
Mass remains constant.
A bowling ball with a mass of 6 kg on
Earth, will have a mass of 6 kg on the
moon.
 WEIGHT
Weight is dependent on the force of
gravity on an object.
 Weight changes with a change in gravity.
 When the force of gravity increases, the
weight of the object increases.
 A person that weighs 120 pounds on Earth
will weigh 20 pounds on the moon
(gravity on the moon is 1/6 that on Earth).

A Weighty Issue: Mass vs. Weight




On which planet did each person weigh the
most? Why?
We weighed the most on Jupiter because it has the
largest gravitational pull of all the planets.
On which planet did each person weigh the
least? Why?
We weighed the least on Mars and Mercury
because of the planets we chose, those two had
the least amount of gravitational force.
What happened to your mass on each planet?
Explain.
Our mass stayed the same. Our mass will not
change even if we travel to another planet. None
of our matter goes away when we travel to another
planet.
What happened to your weight on each
planet? Explain.
Our weight changed on each planet from what it is
on Earth. Weight is a measure of gravitational
attraction. Since the amount of gravitational force
changes on each planet, our weight would have to
change too. Our weight will change because the
gravity on the other planets is different than what
it is on Earth.
Classy Classification
How do you classify the 3 states of matter based on their
properties?
1.
Solid



2.
Has definite volume
Has definite shape
Molecules are close together & are not compressible
Liquid



3.
Has definite volume
Has changeable shape
Molecules take the shape of their container
Gas




Has no definite volume
Has no definite shape
If unconstrained they will spread out indefinitely
Molecules are spread apart
Classy Classification:
Look at Properties: Whole Group
Shoe
Steam from tea pot
Water
What are some of the properties of each of these items?
Classify Classification:
Let’s Classify: Whole Group
1.
Shoe

Has definite volume

Has definite shape

Molecules are close together and are not compressible
IT MUST BE A SOLID!!
2.
Steam from a tea pot

Has no definite volume

Has no definite shape

If unconstrained they will spread out indefinitely

Molecules are spread apart
IT MUST BE A GAS!!
3.
Water

Has definite volume

Has changeable shape

Molecules take the shape of their container
IT MUST BE A LIQUID!!

Classy Classification:
Work With a Small Group to Classify
 Each group will be given a box of different items and
pictures.
 Using the different properties of each state of matter,
the group will classify each item in the box.
