What is a triple beam balance?
100
The amount of matter in an object
What is mass?
100
The formula for density.
What is mass/volume?
100
You can observe and/or measure these properties without changing the identity of the substance.
What are physical properties?
100
The question you are trying to answer.
What is the problem?
200
The type of measurement you make with a graduated cylinder.
What is volume?
200
The amount of space something takes up.
What is volume?
200
The density of water is 1 g/mL. The density of an object is 0.75 g/mL. This will happen when the object is placed in the water.
What is it will sink?
200
When 2 or more substances are changed and a new substance forms.
What is a chemical change?
200
Your educated guess made before the experiment.
What is hypothesis?
300
What you always need to do when working with dangerous chemicals of materials such as salt (even though it's not attractive)
What is wear goggles?
300
The measurement of gravity on an object.
What is weight?
300
The variable found on the x-axis. What you are testing.
What is the independent variable?
300
One example of a chemical change is.....
What is burning, rusting, digestion, etc...
300
The answer to your question, where you also state if your hypothesis was correct or not.
What is the conclusion?
400
The curve you see at the top of a liquid in a graduated cylinder.
What is the meniscus?
400
The unit of volume of a liquid.
What is liters or milliliters?
400
The variable found on the y-axis. This is what you are measuring.
What is dependent variable?

One example of a physical change is......
What is ice melting, water boiling, breaking a pencil, etc...
400
You should always do this to make sure your results are reliable.
What is repeat the experiment?
500
A short, wide container used to measure liquids, but isn't very accurate.
What is a beaker?
500
The process used to find the volume of an irregularly shaped object.
What is displacement?
500
The volume of an object is 4 mL. It's mass is 56 g. What is it's density? You must include the units!
What is 14 g/mL?
500
The process of rusting.
What is oxidation?
500
This type of variable is not on a graph, but is still very important so that your experiment is fair.
What are controlled variables?
