Materials 10 pennies Scale or balance Metric ruler Roll of coins Lab book
3
Vocabulary Balance Gram Meter Millimeter

The standard unit of length in the metric system is the meter. Other units of length and their equivalents in meters are as follows: 1 millimeter = 0.001 meter 1 centimeter = 0.01 meter 1 decimeter = 0.1 meter 1 kilometer = 1000 meters We abbreviate these lengths as follows: 1 millimeter = 1 mm 1 centimeter = 1 cm 1 meter = 1 m 1 decimeter = 1 dm
5
Be sure you use the metric side of the ruler
6
For reference, 1 meter is a little longer than 1 yard or 3 feet. It is about half the height of a very tall adult. A centimeter is nearly the diameter of a dime, a little less than half an inch. A millimeter is about the thickness of a dime.
7
Mass The standard unit of mass in the metric system is the gram. Other units of mass and their equivalents in grams are as follows: 1 milligram = 0.001 gram 1 centigram = 0.01 gram 1 decigram = 0.1 gram 1 kilogram = 1000 grams We abbreviate these masses as follows: 1 milligram = 1 mg 1 centigram = 1 cg 1 decigram = 1 dg 1 gram = 1 g 1 kilogram = 1 kg For reference, 1 gram is about the mass of a paper clip. One kilogram is about the mass of a liter of water.
