Mass
The amount of matter in an object
Volume
The amount of capacity or liquid occupied by an object
Density
Mass/volumecand if something is more dense than water than it will sink
Weight
A measure of the force of gravity on an object
Grams
A unit used to measure mass
Liters
A unit for volume
Meters
Metric unit of length measurement
Cubic Centimeters
A unit to measure volume
Newtons
A unit to measure weight
Triple Beam Balance
A tool used to measure mass
Graduated Cylinder
A tool used to measure liquid volume or for the Displacement method
Displacement Method
An irregular shaped object will be placed in a graduated cylinder to measure the volume of that object
Meniscus
The bottom of the disc in a graduated cylinder when water is inside
What tool is used to measure mass
Triple Beam Balance
What tool is used to measure length
meter stick

Spring Scale
Viscosity
A liquid's resistance to flow
What unit is used to measure mass
Grams
What unit is used to measure volume
Cubic Centimeters (cm3) or for liquid a Graduated Cylinder
What unit is used to measure density
You can do Mass/Volume
What unit is used to measure weight
Newtons
How to find the volume of regular objects
Use a metric ruler and measure height, length, and width
How to find the volume of irregular objects
Use the displacement method or if its bigger than a graduated cylinder put the object in a beaker and the water that comes out pour into a graduated cylinder
How to find the volume of liquids
Use a graduated cylinder and pour inside
How to find the mass of a solid
Use a triple beam balance ot electric scale
How to find the mass of a liquid
Put liquid into a graduated cylinder and measure with an electronic scale than subtract the graduated cylinder's mass
List the units for measuring from smallest to largest
millimeter, centimeter, decimeter, meter, dekameter, hectometer, and kilometer
Compare mass and weight
Mass is the amount of matter you have or an object has and never changes unless you cut off or add. Weight depends on the gravitational pull of where you are.
What is the formula for density
Mass divided by Weight M/V
Think if a heart
Calculate desity given mass and volume
Mass= 9 grams Volume = 9 cm3
9/9=3 g/cm3
Explain how to find the density of any object
Divide mass by weight
What is the density of water
1 g/mL
Why does an object float or sink. Relate to density.
If the object is denser than water it will than sink because it has more molecules packed into it. It will float if it is less dense than water because less molecules are packed into the object.
