Density
What is D=M/V
What is the formula for density?
What is the definition of mass?
What is the measure of how much matter is in an object.
What is the definition of volume?
What is the amount of space an object occupies.
A graduated cylinder has 50ml of water. You drop a cube into the cylinder and the water level rises to 68ml. What is the volume of the cube?
What is 18 mL
What is the density of pure water?
What is 1.0 g/cm^3
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.

What is multiples of 10?
What will happen if you drop an object with a density of 8 g/ml into a liquid that has a density of 1.33g/cm3?
It will sink.

No
What is the curved surface you seen when you measure the volume of a liquid in a graduated cylinder?
What is the meniscus.
What is the volume of a cube with a length of 27 cm, a width of 3 cm, and a height of 8 cm?
What is 648 cubic centimeters.
Describe one useful way in which density data can be used.
Density data can be used to:
-identify unknown materials
-determine whether an object will sink or float
What has more mass, a kilogram of feathers or a kilogram of bricks?
Trick question, their masses are the same, their densities are different.
What is a way to find the volume of an irregular object?
Displacement What is dropping the object in water and calculating the rise of the water from the object being dropped in it.
