1. Lesson 2: Metric Mania Metric Measurements, Tools, Formulas and Conversions

2. What is the Metric System and Why is it important?  AKA “International System of Units” or “SI”  Used throughout the world  Used in science

3. Measurements in the Metric System Scientific Tool MeasurementUnits Temperature Gram (g) Time Metric Ruler Liters (L), Milliliters (mL), Cubic Centimeters (cm³) Graduated Cylinder (Liquids) Metric Ruler (Solids) Triple-Beam Balance Clock, Stopwatch Thermometer Degrees Celsius (°C) Mass Second (s) Length Millimeter (mm), Centimeter (cm), Meter (m) Volume

4. ***S.T.A.R.*** (Something To Always Remember)  All measurements have two parts:  The _________________ and  The _________________ number units

5. Metric Conversions  For Temperature, use page ____ in your Earth Science Reference Table  Examples:  15°F = ______  20°C = ______

6. Metric Conversions (cont.)  Commonly used prefixes for measurement include…  “kilo” – 1000 (thousand)  “centi” – 1/100 or 0.01 (hundredth)  “milli” – 1/1000 or 0.001 (thousandth)

7. Closure Question  What tool is used to measure…  Temperature?  Mass?  Volume?  Length?  Time?

8. Formulas in the Metric System  Volume of Solids = length * width * height
