1. MASSis the amount ofMATTERthat makes up an object

a. (e.g. book, you, air, etc…)

2. SI / metric unit of MEASUREMENTof mass = GRAM (g)

a. the basic SI unit of measurement for MASS = “kg”

3. The “10 little BOXES” for MASS:

1,000,000 mg 1,000 mg

100,000 cg 100 cg

10,000dg 10 dg

1,000 g (1 dollar bill)

100 dag 10,000mg

1,000kg 10 hg 1,000 cg 100 mg

(mega-gramor 100 dg 10 cg

metric ton) 10 g

100,000 mg 10 mg

10,000cg

1,000 dg

100 g 1 mg

10 dag (a grain of sand)

4. The instrument used to measureMASS is aBALANCE

a. a BALANCEmust be “CENTERED” before using

5. Going from a LARGE named unit to a SMALL unit, you MULTIPLY

6. Going from a SMALL named unit to a LARGE unit, you DIVIDE

7. Each HOOP is valued at “x 10” which can be used to determine the

number needed toMULTIPLYorDIVIDEby

(i.e.) 72kg = 7,200dag

(i.e.) 39.1cg = 3.91dg

8. MASS versus WEIGHT:
