The Metric System (Day 1) SI (System International) 9/15/10

5
Metric System Used by every country in the world, except the USA. Always used by scientists. Also called SI, which is French stands for System International. Based on the number 10, so it’s easy!

6
Measuring Length Length is the distance between two points. Basic unit = meter. Meter = m We use rulers or meter sticks to find the length of objects.

7
Measuring Mass Mass is the amount of matter (stuff) that makes up an object. Basic unit = gram.(g) Measure using scales

8
Measuring Volume Volume is the amount of space contained in an object. Base unit = Liter (L). We measure volume with a graduated cylinder or beaker.

9
Measuring Temperature Temperature is the measure of the average heat or heat energy Basic unit= degree Celcius (°C) 0°C= freezing, 100°C boiling We use thermometers to measure temperature.

10
Let’s review our basic units!!! Length Meter (m) Mass Gram (g) Volume Liter (L) Temperature °C We need more accuracy We can’t measure everything with just basic units We need prefixes!

11
Metric Prefixes Common prefixes from large to small: kilo (k) - 1000 centi (c )- 1/100th milli (m)- 1/1000th We can add these prefixes before any of our basic units to make new units that are smaller or bigger!!! Example: killogram (kg) = 1000 g 100 centimeters (cm) = 1 m 1000 milliliters (mL) = 1 L

13
mm cm

14
DO NOW Fri, 09/18 On your DO NOW sheet under today’s date answer all of the following: 1. Turn in your HW #2! 2. How many cm in 1 m? 3. Which is bigger, 5 cm or 55 mm? 4. What units do we measure volume in? 5. Today the temp will be 22 °C. Is this hot or cold? How much is it in ° F?
