1. Measure for Measure Chapter 1 Sec 3

2. A Standard Measurement System
What we know of the metric system:
-Minimizes confusion among scientists all over the world.
-Developed in France
-Uses multiples of 10

3. Length -SI unit for length = meter (m)
-Very large objects in Kilometer (km)
-Common tool-Metric Ruler

4. Weight and Mass -Weight is based on the pull of gravity on your mass
-Weight-a measure of the force of gravity on an object measured in Newtons (N)
-Weight is based on the pull of gravity on your mass
-Weight depends on location

5. Mass a measure of the amount of matter an object contains
-Mass does not change with location
Measured in kilograms (kg)
-Common tool- triple beam balance

6. Time
-SI unit for time is the second (s)
-Common tool – stopwatch

7. Temperature -Celsius Scale-temp scale - water freezes at 0
degrees and boils at 100 degrees
-Kelvin Scale-temp scale - zero is the temp at which
no more energy can be removed from matter
-measured in Kelvin (K)
-Temperature 0°K is called Absolute Zero
-Absolute zero is equal to -273°C
-Common tool - thermometer

8. Volume -the amount of space an object takes up
-measured in cubic meters (m3)
-other common units are
-Liter (L) or Milliliter (mL) for liquids
-Cubic Meter (m3) or Cubic Centimeter (cm3) for solids
1.0 cm3 = 1.0 mL
-Meniscus-the curved upper surface of a liquid in a column
of liquid.
-Volume of solids L x W x H

9. Density -Density-is mass per unit Mass (g) Density (g/cm3) = ---------
(g/mL)
Volume (cm3 or mL)
 -SI unit for Density is kg/m3
-Sink or Float????
-objects sink if their density is more than that of water
-objects float if their density is less than that of water
-Density of water = 1.0 g/mL
