The two measurements you need before you can calculate density are
What is mass and volume
200
A representation of a real system or process that helps you understand this system better can be called this
What is a model
200
The best tool to measure volume
What is graduated cylinder (beaker is acceptable as well)
200
This is the unit most typically used when measuring volume with the graduated cylinder
What is mL - milliliters
200
The mathmatic equation for density is
What is Density is M/V or mass divided by volume
300
The defining feature of a system is this
What is interaction
300
This measurement is good when we want to know how much matter is in an object and how much space it takes up
What is density
300
A kilo- is equal to this on the metric staircase
What is 1000
300
In the liquid density tower experiment that we did (oil, water and maple syrup - which liquid was the most dense and how did you know
What is the maple syrup - it sunk to the bottom
400
How do models compare to real world objects
What is they are much simpler (less detailed)
400
A standard way of measuring is important because
What is so that scientists are using the same data (speaking the same language, or so no mistakes are made)
400
If you wanted to measure the mass of a person,this metric unit would be best
What is kilogram
400
If you had a rectangular box that was 2 cm X 2 cm X 3 cm tall and it had a mass of 24 grams - the density would be
What is 2 g/cm^3
500
Why has the model of an atom changed so much over time?
What is more discoveries have been made and scientist had to rethink their theories
500
If you have an irregular shaped object, the method you would use to measure it
What is water displacement method
500
These are the base units of the metric system
What is meters, liters and grams

I had a graduated cylinder filled with 10 ml of water. I dropped a marble in and it rose to 12 ml. The marble had a mass of 8 grams. The density of the marble would be
