This is the SI unit for length.
What is meter?
100
These two units are interchangeable even though one is for solids and the other is for liquids. It's a good thing too, because it allows us to convert easily back and forth.
What is centimeters cubed and milliliters?
100
A balance scale is for measuring this.
What is mass?
100
The variable that is changed by the experiment is called this.
What is manipulated (or independent) variable?
100
This is the number of significant figure in 3.50
What is three? (Because the zero is after the decimal it counts as a significant figure)

The width of your pinky is a good approximation for this SI unit.
What is a centimeter (or cm)?
200
This is the volume of a rectangular prism which measures 10.5 meters by 6 meters by 10 meters. (Don't forget units!)
What is 630 m^3?
200
This is the basic units for mass.
What is grams?
200
When designing experiments, these are things kept the same so as to increase reliability in the experiment.
What is controlled variables?

A ruler has tic marks that are .1 cm apart. This would be the most accurate measurement allowed. (A) 3 (B) 3.1 (C) 3.14 (D) 3.141 (E) 3.1416
What is (C) 3.14 as you can estimate one more place value from the given scale.
300
This is the number of PLACES and DIRECTION you would shift the decimal point to convert from mm to meters.
What is three to the left?
300
A graduated cylinder contains 34 ml of water. After dropping in 8 equal sized marbles, the volume of the water reads 50 ml. This the volume of each marble.
What is 2 ml? (The difference between 50 and 34 is 16 ml, so 16ml divided by 8 marbles is 2 ml per marble)
300
A spring scale measures this.
What is force and/or weight?
