MASS
HOW IS MASS DIFFERENT FROM WEIGHT?
WEIGHT
Mass is a measurement of how much matter is in an
object or substance.
Weight is a measurement of how strongly GRAVITY
is PULLING an object DOWN.
Weight changes when gravity changesso on the
moon where there is less gravity, you will weigh
less, but on the sun you would weigh more!
Mass does NOT change if you travel to another
planet.
ON EARTH Mass 64.5 kg Weight 140 lbs
ON MOON Mass 64.5 kg Weight 23 lbs
ON SUN Mass 64.5 kg Weight 3,914 lbs

FINDING THE MASS OF OBJECTS USING A TRIPLE-BEAM
BALANCE
6
To find the MASS (the amount of matter) in an
object, you can use a tool called a TRIPLE-BEAM
BALANCE
TRIPLE-BEAM BALANCE
Beams
Riders
Pan
Pointer (at zero)

READING THE MASS ON A TRIPLE-BEAM BALANCE
1) Read the number on the HUNDREDS BEAM
30 grams

• Add the number on
• the TENS BEAM

100 grams

• Add the number on the
• ONES BEAM
• Any marks past the
• number on the ones
• beam are to be read
• as TENTHS using a
• DECIMAL POINT first.

7.4 grams
The object measured on this balance has a mass
of 100 30 7.4 137.4 grams

What is the mass of the object on this
triple-beam balance?
300 70 3.3

Lets find the mass of some objects at your desk!
Make sure the pointer on your balance is set at
ZERO. Place an object on the pan. Follow the
STEP-BY-STEP directions in your notes for
