200
This is the range of the data 5cm,11 cm,14cm.
What is 9cm?
200
This is the substance used to reduce friction.
What is a lubricant?
200
This is what happens to an object that is denser than the substance in which it is placed.
What is sink?
200
This is the variable that is measured or observed and not directly manipulated by the scientist?
What is the dependent variable?
200
This it the SI unit of measurement used to measure mass.
What is kilograms?
300
The number determining the value of each line on the x or y axis is known as this.
What is the scale?
300
According to Newton's third law, for every action there is this...
What is an equal and opposite reaction?
300
This is the relative density of an object that floats in water (1 g/mL) but sinks in oil (0.9 g/mL).
What is greater than 0.9 g/mL but less than 1g/mL?
300
This is the reason constants exist in an experiment.
What is to ensure that the only variable causing changes in the dependent variable is the independent variable?
300
This is a variable that should not be changed between groups in an experiment?
What is a constant?
400

What is an unbalanced force?
400
This is the reason a submarine is able to sink?
What is by filling its ballast tanks with water (displacing the air inside and making the overall density of the submarine greater than water)?
400
This is a fact about the variables that is collected using your 5 senses.

500
This is the density of an object that is floating but with 62 percent of it submerged in the water?
What is 0.62 g/mL?
500
This is a part of an experiment that should be very clear and logical, using specific details to make it replicable.
What is the procedure?
500
This variable is measured in Joules?
