SI/Metric The international system of units (SI) is a version of the metric system that modern scientists use. WE DO NOT USE THE STANDARD SYSTEM IN SCIENCE! http://chartsbin.com/view/d12
Length • Length is measured in meters Kilometers 1000 Hectometers 100 Dekameters 10 Meters Decimeters 0.1 Centimeters 0.01 Millimeters 0.001
Mass • Mass is measured in grams Kilograms 1000 Hectograms 100 Dekagrams 10 Grams Decigrams 0.1 Centigrams 0.01 Milligrams 0.001
Volume • Volume is measured in Liters OR cm³ Kiloliters 1000 Hectoliters 100 Dekaliters 10 Liters Deciliters 0.1 Centiliters 0.01 Milliliters 0.001
Other SI Units • Time is measured in seconds (milliseconds are also often used) • Weight is measured in Newtons • Temperature is measured in Celsius or Kelvin
Since each step is ten times or one-tenth as much as the step on either side, we have: 1 kilometer = 10 hectometers = 100 dekameters = 1000 meters = 10 000 decimeters = 100 000 centimeters = 1 000 000 millimeters • Or: 1 milliliter = 0.1 centiliters = 0.01 deciliters = 0.001 liters = 0.000 1 dekaliters = 0.000 01 hectoliters = 0.000 001 kiloliters
Density • mass ÷ volume = density • grams ÷ cm³ = g/ cm³ OR grams ÷ Liters = g/ L What makes me float? Hmmm . . . Which ones will float and which ones will sink?
Metric System Foldable (page 18 of our notebook) • Fold paper in half • Draw a line every 3 centimeters • Cut stairs • Cut front half of paper down line • Label inside and outside • Things to label: • King Henry . . . (outside) • Kilo-, Hecto-, . . . (inside) • Under base meter, liter, gram • Abbreviations (inside)
there was a really talkative student. Mrs. Supan’s evil twin taught this student and she knew that the talkative student needed to be taught a lesson. She found a roll of duct tape that measured 44.5 cm. The talkative student’s mouth measured 150.4 mm. Mrs. Supan’s evil twin wondered if she had enough tape to cover . . . *No students were harmed in the making of this word problem*
