The density of an object depends on its _______ and _______.
mass, volume
mass, matter
volume, space
space, dimension
The mass of an object is the amount of ___________ in the object.
energy
gravity
matter
space
The volume is the amount of _______ that the object takes up in three dimensions.
Space
Mass
Liquid
Density
Density = ????
volume/mass
mass*density
mass/volume
Mass-Volume
If something has a large mass compared to its volume it would have a ______________ density.
high
low
normal
small
What example do they give of an object with high density?
Weights
Apple
Computer
If an object has a small mass compared to its volume it has a _____________ density.
high
low
normal
small
What example did they give of an object with a lower density?
Weights
Apple
Computer
The density of a material is based on________________________________?
Atoms or molecules the substance is made from
Weight
How big the object it
Balance of an object
The copper and aluminum cubes are the same size (volume), but different masses. Which cube is more dense?
copper
aluminum
What are some possible reasons why the copper cube is more dense?
Copper atoms might have more mass than aluminum atoms.
Copper atoms might be smaller than aluminum atoms so more can fit in the same volume.
Copper atoms might be arranged differently than aluminum atoms so more can fit in the same volume.
All of the above.
As it turns out, which of the above options is true for copper and aluminum atoms?
Copper and aluminum atoms are arranged the same way but copper atoms are smaller and have more mass than aluminum atoms.
Copper and aluminum atoms are arranged the same way but copper atoms are bigger and have less mass than aluminum atoms.
A sample of a substance with a higher density will always have a _______ mass than the same size sample of a substance with a lower density.
lower
greater
more colorful
weirder
A small sample of a substance with a high density may weigh as much or more than a larger substance with a ________ density.
lower
higher
Select all statements below that are true:
Mass is the measure of the amount of matter that makes up an object. Weight is a measure of the force of gravity on a certain mass.
A bowling ball would weigh less on the moon than on earth.
The mass of the bowling ball is the SAME on earth and the moon, even though the weight is different.
The mass of the bowling ball is DIFFERENT on earth and the moon.
Why doesn't scale always measure weight, how is it that a scale is able to measure mass (the amount of matter in an object)?
The scale is calibrated so that it does an internal calculation to factor out the effect of gravity and display only the mass of the object.
The scale is a magical device, there is something really spectacular about its ability to determine the difference between mass and weight.
A copper cube the same size as a plastic and wood cube is _________ dense than those cubes.
less
more
True or False: Atoms in a copper cube are more tightly packed together than the carbon and hydrogen atoms that make up the plastic cube. This makes the copper cube more dense than the plastic cube.
True
False
Wood is made of the following elements/atoms?
Carbon
Aluminum
Hydrogen
Oxygen
What is a method that we can use to find the volume of an irregular shaped object that is not easily measured with a ruler or other device?
protractor
volume displacement method
measuring cup
graduated cylinder
What is the formula you use for volume displacement?
volume of solid= millimeters- cubic centimers
volume of solid= initial volume-final volume
volume of solid= final volume - initial volume
volume of solid= cups - inches
The initial volume of the water in a graduated cylinder is 60 mL. If you put an irregular shaped solid object in a graduated cylinder to find its volume, and the final volume of the water + the solid is 72 mL, that means the volume of the object is _______.

(volume of the solid= final volume- initial volume)
-12 mL
8 mL
10 mL
12 mL
The density of a substance is the __________ no matter what the size of the sample.
greater
less
same
all of the above
The example they gave to explain that the density of an object is the same no matter its size is:
a small piece of wax is the same density as a large piece of wax.
a small piece of wax is NOT the same density as a large piece of wax.
Why is it possible for the heavier wax candle to float and the lighter clay to sink?
This is possible because the density of the candle is less than the density of water, therefore it will float in the water.
This is possible because the candle is more dense than the density of water, therefore it will sink in the water.
An object that is ________ dense than water will float in the water.
less
more
same
all of the above
Clay is more dense than water because....
The atoms making up the clay are lighter than the atoms in the water.
The atoms making up clay are heavier than the atoms in water.
In a density column, the liquids that settle on the bottom of the density column are ___________ than the liquids on the top.
more dense
less dense
Increasing mass a lot, and the volume just a little, will result in an _________ in density.
settling
lightening
decrease
increase
In the example given, if enough salt dissolves in the water, then the density of the water will ________________ enough to be more dense than the carrot.
decrease
increase
remain the same
all of the above.
