Everything that has mass and takes up
space is matter.
Have students look at the photograph
on pp. 6–7. Ask them to list ten objects
or substances that represent different
states of matter in the photograph. Have
them explain what makes each object
matter. Each object has mass and takes

KEY CONCEPTS SUMMARY
SECTION 1.1
Ask: Which tools are being used to
measure mass and volume? a pan bal-
Mass is a measure of how much
matter an object contains.
ance to measure mass and a graduated
cylinder to measure volume Ask: Which
1.2
Volume is the measure of the
amount of space matter occupies.
Matter is made of atoms.
VOCABULARY
atom p. 16
molecule p. 18
An atom is the smallest basic unit of
matter. Two or more atoms bonded
together form a molecule. Atoms
and molecules are always in motion.
tool would you use to measure the volume of a box? a ruler or meter stick
SECTION 1.2
Ask: How many different kinds of atoms
formed the molecule? two
1.3
Matter combines to form different substances.
VOCABULARY
element p. 22
compound p. 23
mixture p. 23
SECTION 1.3
Ask: Which picture shows a pure substance? Explain. The picture on the
left of the gold coins shows a pure
substance. The coins contain only one
substance, the element gold.
Matter can be pure, such as an
element (gold), or a compound
(water).

SECTION 1.4
Ask: Which state of matter has a fixed
volume but takes the shape of the container it is in? liquid
Matter exists in different physical states.

Thinking Critically
Short Answer Answer each of the following
questions in a sentence or two.
23. Matter: wood, metal, water, air;
Not Matter: light, sound
Use the information in the photograph below
to answer the next three questions.
19. Describe the movement of particles in a solid,
a liquid, and a gas.
24. No; you would have carbon and
oxygen atoms. A molecule is the
smallest part of a compound that is
still that compound.
20. In bright sunlight, dust particles in the air
appear to dart about. What causes this effect?
21. Why is the volume of a rectangular object
measured in cubic units?
25. Like a liquid, sand has a definite
volume but takes the shape of its
container as sand grains slide
around. Unlike a liquid, sand is
made up of individual grains that
each have a definite volume and
a definite shape.
50 mL
58 mL
22. Describe how the molecules in the air behave
when you pump air into a bicycle tire.
Thinking Critically
23. CLASSIFY Write the headings Matter and
Not Matter on your paper. Place each of these
terms in the correct category: wood, water,
metal, air, light, sound.
26 Many of the gas molecules escape
into the air outside the ball.
24. INFER If you could break up a carbon dioxide
molecule, would you still have carbon dioxide?
Explain your answer.
27. Mixtures: substances remain the
same, separated by physical means,
percentages of substances can vary;
Compounds: new substances formed,
separated by breaking bonds, percentages of substances fixed; Alike:
combinations of substances
25. MODEL In what ways is sand in a bowl like a
liquid? In what ways is it different?
26. INFER If you cut a hole in a basketball, what
happens to the gas inside?
31. INFER One way to find the volume of a marble
is by displacement. To determine a marble’s
volume, add 50 mL of water to a graduated
cylinder and place the marble in the cylinder.
Why does the water level change when you
put the marble in the cylinder?
32. CALCULATE What is the volume of the marble?
33. PREDICT If you carefully removed the marble
and let all of the water on it drain back into
the cylinder, what would the volume of the
water be? Explain.
27. COMPARE AND CONTRAST Create a Venn
diagram that shows how mixtures and
compounds are alike and different.
28. The ball is a solid; the molecules
are fixed in place and cannot move
easily.
29. 720,000 cm3
30. 2 trips
31. The marble displaces the liquid.
32. 8 mL or 8 cm3
28. ANALYZE If you place a solid rubber ball into
a box, why doesn’t the ball change its shape
to fit the container?
34. SYNTHESIZE Look back at the photograph on
pages 6–7. Describe the picture in terms of
states of matter.
29. CALCULATE What is the volume of an
aquarium that is 120 cm long, 60 cm wide,
and 100 cm high?
35. WRITE Make a list of all the matter in a twometer radius around you. Classify each as a
solid, liquid, or gas.
30. CALCULATE A truck whose bed is 2.5 m long,
1.5 m wide, and 1 m high is delivering sand
for a sand-sculpture competition. How many
trips must the truck make to deliver 7 cubic
meters of sand?
33. 50 mL; the volume of the water
does not change and the marble is
no longer displacing any of it.
If you are doing a unit project, make a folder for
your project. Include in your folder a list of the
resources you will need, the date on which the
project is due, and a schedule to track your
progress. Begin gathering data.
34. Answers should categorize items as
solids, liquids, and gases.
35. Answers might include water (liquid), air (gas), and table (solid).
