1. Measurement

2. Scientific Measurment
Scientists use a common system of units called the International System of Units.
This can be abreviated “SI Units”
This allows scientists to share information more easily.

3. Length SI Unit – meters Abbreviation – m
Tool used to measure – meter stick

4. Mass SI Unit – kilogram Abbreviation - kg
Tool used to measure - balance

5. time SI Unit – seconds Abbreviation - s
Tool used to measure - stopwatch

6. Volume FOR LIQUIDS SI Unit – liters Abbreviation - L
Tool used to measure – graduated cylinder
FOR SOLIDS
SI Unit – cubic centimeters
Abbreviation – cm3
Tool used to measure – meter stick
Length x width x height
1 cm3 = 1 mL

7. Temperature SI Unit – kelvin or celcius Abbreviation – K of C
Tool used to measure – thermometer
°C = K
Boiling Point of Water
212°F=100°C=373 K
Freezing Point of Water
32°F=0°C=273 K

8. Volume
To find the volume of an iregular solid use the displacement method.
First measure the volume of liquid in a beaker.
Place the irregular object into the liquid.
Measure the new volume of the liquid.
Subtract the first volume from the second.
The difference between the two is the volume of the irregular solid.

1 m = .1 dkm = .01 hm = .001 km
1m = 10 dm = 100 cm = 1000mm

12. Significant Figures
The significant figures of a measure show the precision that you know for sure
When working a problem, you can only have as many significant figures as your lowest significant figure in the answer.
All non-zero numbers are considered to be significant.
Zeros between two significant numbers are considered to be significant
Zeros to the right of a significant figure on the right of a decimal are considered significant
Zeros to the right of a significant number with no decimal are not significant
