3. SI Measurements (also known as “metric system”) “SI” stands for “System International” or “International System of Measurement”

4. What about it? –Common Language for scientists –Based on units of 10 –Multiply or divide to go up or down when converting units –Prefixes determine “how much” of a unit SI Measurements (also known as “metric system”)

5. Important BASE units to remember: METERS = m (measures distance or length) ruler/meterstickMeasure with ruler/meterstick

6. LITERS = L (measures volume — how much space something takes up) graduated cylinder/beakerMeasure with graduated cylinder/beaker Or with a ruler (length x height x width)Or with a ruler (length x height x width)

7. g GRAMS = g (measures mass) triple beam balance/scaleMeasure with triple beam balance/scale

8. o C o CELSIUS = o C (measures temperature) thermometerMeasure with thermometer

9. Important PREFIXES to remember: 1000 k = kilo- (means “1000”) 100 h = hecto-(means “100”) 10 D (da) = deca-(means “10”) BASE UNIT (liter, meter, gram) 1/10” or 0.1 d = deci-(means “1/10” or 0.1) 1/100 c = centi- (means “1/100” or.01) 1/1000 m = milli- (means “1/1000” or.001)

10. How to Measure lengthwidth AREA = length X width SquaredUnits: Squared Units m 2, cm 2, km 2Examples: m 2, cm 2, km 2

11. How to Measure matter MASS : measure of the amount of matter in an object Use a Triple Beam Balance to add the ones, tens, and hundreds grams units ** Triple Beam Balance Practice Sheet**

12. How to Measure 3-D VOLUME : how much space a 3-D object takes up Liters/mLUnits for liquids: Liters/mL cm 3Units for solids: cm 3 ** Graduated Cylinder Practice Sheet**

13. How to Measure matter volume DENSITY = amount of matter in a given volume massDensity = massvolume Units: g/mL OR g/cm 3
