3. Mass - the amount of matter an object has. Matter- something that has mass and takes up space. Weight- is the amount of mass of an object, it is dependent upon gravity.

4. *The Triple Beam Balance is the tool we use to measure mass.

5. MASS vs. WEIGHT  Always remains constant Depends on gravity  Does not depend on gravity weight= mass x gravity weight of an object changes if the gravity changes

6.  1 pound = 453,59 grams  1 ounce = 28.34 grams  1 ounce = 0.0625 pounds  1 ounce = 28,349.52 milligrams

7. 10 milligrams (mg) =1 centigram (cg) 10 centigrams =1 decigram (dg)= 100 milligrams 10 decigrams =1 gram (g)= 1,000 milligrams 10 grams =1 dekagram (dag) 10 dekagrams =1 hectogram (hg)= 100 grams 10 hectograms =1 kilogram (kg)= 1,000 grams 1,000 kilograms =1 metric ton (t)

8.  Kilograms  Hectograms  Dekagrams  Grams  Decigrams  Centigrams  Milligrams  Tonnes (1000kg)

10.  1 Pound or 100 Grams  1 Kilogram or 1 Pound  1 Ounce or 1000 Milligrams  1 kilogram or 1500 grams  1200 milligrams or 1 gram  12 milligrams or 12 kilograms  4 kilograms or 4500 grams
