MASS WEIGHT HOW IS MASS DIFFERENT FROM 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 changes…so 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

To find the MASS (the amount of matter) in an object, you can use a tool called a TRIPLE-BEAM BALANCE TRIPLE-BEAM BALANCE Pan Riders Beams 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 = 373.3 grams 70 g 300 g 3.3 g

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
