5. The Metric System SI (System International)

6. Metric System Used by every country in the world, except the USA. Used by every country in the world, except the USA. Always used by scientists. Always used by scientists. Based on the number 10, so it’s easy! Based on the number 10, so it’s easy!

7. Measuring Length Length= the distance between 2 points. Length= the distance between 2 points. Base unit= meter (m) Base unit= meter (m) Use rulers and meter sticks to measure Use rulers and meter sticks to measure

8. Measuring Mass Mass is the amount of matter (stuff) in an object. Mass is the amount of matter (stuff) in an object. Base unit = gram (g) Base unit = gram (g) Use scales to measure. Use scales to measure.

9. Measuring Volume Volume is the amount of space in an object. Volume is the amount of space in an object. Base unit= Liter (L) Base unit= Liter (L) Use a beaker or graduated cylinder to measure. Use a beaker or graduated cylinder to measure.

10. Measuring Temperature Temperature is the measure of the average heat energy Temperature is the measure of the average heat energy Base unit= degree Celcius (°C) Base unit= degree Celcius (°C) 0°C= freezing, 100°C boiling 0°C= freezing, 100°C boiling Use thermometers to measure. Use thermometers to measure.

11. Let’s review our basic units!!! Length Length Meter (m) Meter (m) Mass Mass Gram (g) Gram (g) Volume Volume Liter (L) Liter (L) Temperature Temperature °C °C Problems: We need more accuracy We need more accuracy We can’t measure everything with just base units We can’t measure everything with just base units We need prefixes! We need prefixes!

12. Metric Prefixes Common prefixes from large to small: Common prefixes from large to small: kilo (k) - 1000 centi (c )- 1/100th milli (m)- 1/1000th We add these prefixes before any of our base units for length, mass or volume to make new units that are smaller or bigger!!! Example: killoleter (kL), kilometer (km) centileter (cL), centimeter (cm) milliliter (mL), millimeter (mm)
