Complete the chart in your notes, and draw and label pictures for each item.
MASS WEIGHTMass is a measurement of how much matter is
in an object or substance.
Mass does NOT change if you travel to another
planet.
Weight is a measurement of how strongly GRAVITY is PULLING an object DOWN.
Weight changes when gravity changes…so on the moon where there is less gravity, you will weigh
less, but on the sun you would weigh more!
HOW IS MASS DIFFERENT FROM WEIGHT?
ON EARTHMass: 64.5 kgWeight: 140 lbs
ON MOONMass: 64.5 kgWeight: 23 lbs
ON SUNMass: 64.5 kgWeight: 3,914 lbs
FINDING THE MASS OF FINDING THE MASS OF OBJECTS USING A OBJECTS USING A
TRIPLE-BEAM BALANCETRIPLE-BEAM BALANCE
To find the MASS (the amount of matter) in an object, you can use a tool called a TRIPLE-BEAM BALANCE
BeamsRidersPan
Pointer(at zero)
TRIPLE-BEAM BALANCE
READING THE MASS ON A
TRIPLE-BEAM BALANCE
1) Read the number on the HUNDREDS BEAM
2) Add the number on the TENS BEAM
3) 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.
100 grams
30 grams
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 g
70 g
3.3 g
300 + 70 + 3.3 =
373.3 grams

Let’s practice reading the measurements on some
balances.
Let’s 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 READING A TRIPLE-BEAM BALANCE
