Density is a ratio of a substance's ______ to its _____
ratio of mass to volume
True or false. You will have the same mass on Jupiter as you do on Earth.
True. Your mass stays the same even if the amount of gravity changes.
If I have a cube that is 1cm on all sides, what is its volume?
What is 1 cm3?
What is the density of a solid object that has a mass of 120g and displaces 20mL of water?
What is 6g/cm3?
What tool is used to measure liquid volume?
What is a graduated cylinder?
What will happen if you drop an object into water that has a density of 1.33g/cm3?
It will sink.
If you have two objects that have the same mass, but different volumes. Which one will have a greater density?
The object with the smaller volume.
What is the curved surface you seen when you measure the volume of a liquid in a graduated cylinder?
What is the meniscus.

How would you find the volume of a necklace?
What is volume displacement?
aka water displacement / displacement method
A substance with a density of 30 g/cm3 is cut into 10 equal pieces. What is the density of each of the pieces?
What is 30 g/cm3?
Are mass and weight the same thing? Explain your answer
No. Mass is the amount of matter in an object, weight is the force of gravity pulling on an object.
What is a way to find the volume of an irregularly shaped object? Name the method and explain the steps.
What is volume displacement? (aka water displacement aka displacement method)
1.Measure the volume of water in a graduated cylinder (starting volume)
2. drop the irregularly shaped object in the cylinder. Measure the final volume.
3. Subtract the starting volume from the final
The starting volume is 14mL.
An object with a mass of 30g is placed in the cylinder. The water rises to 40mL.
What is the object's density?
D = 30g/26cm3
D = 1.15 g/cm3
