# Metric System, Volume, Density, Displacement, Sink or Float

The amount of matter in an object is called its ____ . Mass
The amount of space an object takes up is called its ______. Volume
The amount of matter in the volume is an object's ___________ . Density
The measure of the force of gravity pulling an object down to the earth is the object's ______________ . Weight
What is the formula used to find the volume of a solid object? V = L x W x H
What is the formula used to find the density of an object? D = Mass divided by Volume
If a brick has a volume of 48 cubic centimeters and a mass of 144 grams, what is its density? D = 144g ? 48 cm3 = 3 g/cm3
What tool can we use to measure length, width, and height of an object? A ruler
What tool can we use to measure the amount of matter or mass in an object? triple beam balance
What tool can we use to measure liquids and also the volume of irregularly shaped objects? graduated cylinder
Metric units used to measure liquids include milliliters, liters
Metric units used to measure the mass (amount of matter) in an object grams, kilograms
What does the scientific principle of water displacement say? No two objects can occupy the same space at the same time. That's why liquids move out of the way when an object is dropped into it, and the level rises.
True or False: The weight of an object does not remain constant (does not stay the same) if its location is changed from earth to the moon. True. The weight changes because the force of gravity on the moon is less than it is on earth
To find the volume of a car, you would________________ . Multiply length x width x height
The weight of an object is really a measure of the _______________. Force of gravity pulling it downward to earth
If the density of an object is GREATER than the liquid in which we drop it, then the object will ____________ Sink
If the density of an object is LESS THAN the density of the liquid in which we drop it, then the object will ___________ . Float
