Weight is a measure of how strongly one thing is attracted to another by ______________.
Gravity
200
The Law of Conservation of Energy states that _______ does not go away.
Energy
200
The ________ _______ involves carefully dropping an object into a graduated cylinder and using subtraction to figure out the volume.
Displacement Method
200
Why would Styrofoam be a good insulator of heat?
Because it has tiny air pockets
200
What is a battleship more buoyant than a rock?
The battleship is less dense- more air pockets.
300
The metric system unit for weight is the __________.
Newton
300
The Law of Conservation of Mass and the Law of Conservation of Energy make up the first law of _____________.
Thermodynamics
300
If an object is too big to fit into a graduated cylinder, the _______ _______ can be used to find volume.
Overflow Method
300
If two substances with the same volume have different densities, how can you tell which one is the densest?
The one that is heavier will have the higher density.
300
How are buoyancy and density related?
One substance is buoyant in another (Battleship in Water) if it is less dense than the other substance.
400
In the English system, mass is measured with the unit called a ___________.
Slug
400
If you start with 10 grams of water and you boil it until there is no water left in the pan, what happened to the water?
The 10 grams of water turned into 10 grams of steam.
400
How would you find the volume of a box of crackers?
Side x Side x Side
400
If two objects have the same density and the same size, what will be true about their masses?
They will have the same mass
400
If an object floats in one liquid but sinks in another, what does that tell you about the densities of the two liquids?
The first liquid is denser than the second.
500
If you are using the metric system to measure mass, the units will be in ______.
Grams
500
According to the Law of Conservation of Mass, if you have a 20 gram rock and you hit it with a hammer until it is broken into tiny pieces, what will you have?
Still 20 grams of rock
500
When using a graduated cylinder, you should take the measurement at the lowest point, called the _______________.
Meniscus

Why does the ping-pong ball have a lower density than the golf ball?
The golf ball is filled with air. Air is very light compared to most substances.
