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. 10 milligrams (mg) = 1 centigram (cg) 10 centigrams = 1 decigram (dg) = 100 milligrams 10 decigrams = 1 gram (g)= 1,000 milligrams 1 pound=500 grams 10 grams =1 dekagram (dag) 1 ounce=28.3 grams 10 dekagrams = 1 hectogram (hg) = 100 grams 10 hectograms = 1 kilogram (kg)= 1,000 grams 1,000 kilograms = 1Ton (t)

7.  1 pound = 453,59 grams  1 ounce = 28.34 grams  1 ounce = 0.0625 pounds  1 ounce = 28,349.52 milligrams

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

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
