Measurement Facts Reviewed in Class
 What is common measurement of a: Volume, Mass, Distance?
 Mass is the measurement of how much matter an object contains
 Are mass and weight the same thing?
 What do we use in our lab to Mass object?
 Examine you triple beam balance. What is each beam for?
 What is the least and most mass you can mass on it?
SI Units For: Measurement

Measuring Mass: Mass is the measurement of how much matter an object contains

We use a triple beam balance to measure mass.

Are mass and weight the same thing?

Mass vs. Weight
Weight is a measure of the force of gravity on you 
Mass does not change.

An object’s weight will change if you move it from Earth to the moon or to other planets.

Weight = mass x gravity
Gravity = 9.8 m/s2



Mass is measured in kilograms
A smaller unit is also used 
Grams
Mass is measured using a triple beam balance
Volume

The amount of space that occupies matter
Volume is measured in several units
Liters (L)
Milliliters (mL)
Cubic centimeters (cm3) 
For rectangular objects, volume can be found by multiplying the measurements of length, width, and height
Volume = length x width x height
Length

Length is measured in meters
Meter (m)
Kilometer (km)
Centimeter (cm)
1 kilometer = 1,000 meters
1 centimeter = .01 meters 
Length is measured using a meter stick or a ruler
Temperature

Temperature is measured in degrees Celsius (oC)
Water freezes at 0o Celsius
Boils at 100o Celsius
Mass vs. Weight
 Weight is a measure of the force of gravity on you
 Mass does not change.
 An object’s weight will change if you move it from Earth to the moon or to other planets.
 Weight = mass x gravity
 Gravity = 9.8 m/s2
