1. Vocabulary
Volume: the amount of space occupied by a 3D object 1cm3 = 1mL Matter: Anything that has mass and takes up space

2. Mass
Mass: the measurement of How Much matter is in an object Units = grams (kg  mg)

3. Weight is defined as the force of gravity on an object
Weight is defined as the force of gravity on an object. Your weight can change if the force of gravity changes.
Ex: lbs on Earth = 16.5 lbs on the moon
(6x less gravity on the moon)
Ex: kg on Earth = 100 kg on the moon
(mass is not affected by gravity)

4. Triple Beam Balance Used to measure mass
Compares a known mass to an unknown mass
Unaffected by gravity

5. Steps to use TBB All known masses to the left. Balance at Zero
Add the object
Move known masses until pointer is back to zero
a. Start with 2 larger masses
b. Use small mass to accurately measure to
the nearest 0.1g
c. Add up all 3
