What is density?
How do you find density?
What happens to density as mass increases and volume stays the same? (plug in easy numbers
into the formula to find out)
What happens to density as volume increases and mass stays the same?
What is the unit for density?
What is the density of water?
Lucy told her teacher that she couldn’t complete her homework assignment because the objects
she was supposed to measure fell in her pool and sunk to the bottom. The objects were a fired
clay pot (1.36g/cubic centimeters) and a copper spoon (8.93g/cc). How did Mrs. Cifuentes know
if Lucy was truthful in saying the objects sunk based on her knowledge of density?
Substance
Water
Fired clay pot
Copper spoon

How much does 1 mL of water weigh?
Density
1 gram per cubic centimeter (1 g/cc)
1.36 g/cc
8.93 g/cc
Mass
Relationship to 1 gram
Example
Milligram (mg)
1/1000 of a gram
Gram (g)
1 gram
The brain of a worker honeybee, A very
small snowflake (though they can weigh up
to 500 milligrams)
A feather, a paper clip and a US dollar bill
each weigh one gram on average
Kilogram (kg)
1000 grams
1 liter of water, a pineapple, a dictionary

TEACHER STUDY GUIDE: CHEMISTRY
What is matter? ANYTHING THAT HAS MASS AND TAKES UP SPACE
What is volume? ANYTHING THAT TAKES UP SPACE
International System of Units/Metric System: BASE-TEN SYSTEM, USED IN SCIENCE, EX: CM, M
U.S. Customary System/English System: USED IN THE U.S., EX: INCHES, FEET, MILES
What is density? HOW COMPACT MATTER IS OR HOW MUCH MATTER IS IN A VOLUME
How do you find density? MASS/VOLUME
What happens to density as mass increases and volume stays the same? (plug in easy numbers into the
formula to find out) 10/5=2<20/5=4, DENSITY INCREASES
What happens to density as volume increases and mass stays the same? DENSITY DECREASES
What is the unit for density? G/ML OR G/CM3
What is the density of water? 1 G/ML

MRS. C KNEW BECAUSE EACH ITEM HAD A DENSITY GREATER THAN WATER’S 1 G/CC AND WOULD
THEREFORE SINK
What metric units measure length? CM, M, KM
What metric units measure volume? MILLILITERS (ML), LITERS (L), CUBIC CENTIMETERS (CC), CM3
What metric units measure mass? GRAMS (G), KILOGRAMS (KG)
1 mL=? cubic centimeters? 1ML=1 CC

How do you find the volume of a rectangular prism? LENGTH X WIDTH X HEIGHT=VOLUME
Given the length of a side of a cube, could you find the volume? EX: SIDE=4CM, 4X4X4=64
What's the difference between mass and weight? MASS IS CONSTANT, WEIGHT CHANGES DEPENDING ON
GRAVITY
What method can you use to find the volume of an irregularly shaped object? WATER DISPLACEMENT
What measurement tool would you use to find...
Length: RULER
Mass: BALANCE
Volume: GRADUATED CYLINDER
What is the definition of a physical property? AN OBSERVABLE, MEASURABLE CHARACTERISTIC OF
MATTER
What are examples of physical properties? DENSITY, MASS, VOLUME, LENGTH, MAGNETISM, COLOR, SIZE,
TEXTURE, STATE OF MATTER
What is evaporation? PROCESS OF CHANGING A LIQUID TO A GAS
What is condensation? PROCESS OF CHANGING A GAS INTO A LIQUID
What is cohesion? ATTRACTION BETWEEN MOLECULES
What is surface tension? ATTRACTION BETWEEN MOLECULES ON THE SURFACE OF A LIQUID
What are the 3 states of matter? SOLID, LIQUID, GAS
What is a mixture? 2 OR MORE PURE SUBSTANCES COMBINED PHYSICALLY
What are some methods of separating a mixture? FILTRATION, EVAPORATION, MAGNETISM, HANDPICKING, SEDIMENTATION
Does a fragment (piece) of a pure substance have the same properties as the whole? YES
Which two things on this list are mixtures (vs. pure substances): Water, baking soda, sugar, salad dressing,
cement? SALAD DRESSING (MIXTURE OF OIL, VINEGAR, SPICES, ETC.), CEMENT (MIXTURE OF ROCKS,
