  3. Class Reading : Lab Safety Symbols (p.686-687)

  4. Metrics Review

  5. What is the standard system of measurement used by scientist around the world? • S_______ I______________ • SI • International System of Units • Metric System ystem nternational

  6. What is the SI unit for measuring length? eter • M____________

  7. What is the SI unit for measuring Liquid Volume? iter • L____________

  8. What is the SI unit for measuring Mass? ram • G____________

  9. What is the SI unit for measuring Temperature? elsius • C____________

  10. How do we measure smaller and larger objects in SI units? Through Prefixes Kilo- X1000 Hecto- X100 Deca- X10 Deci- 1/10 Centi- 1/100 Milli- 1/1000

  11. Here is another way to remember the prefixes King Henry Does Drink Chocolate Milk Kilo- X1000 Hecto- X100 Deca- X10 Deci- 1/10 Centi- 1/100 Milli- 1/1000

  12. How many meter is kilometer? 1000 meter Kilo- X1000 Hecto- X100 Deca- X10 Deci- 1/10 Centi- 1/100 Milli- 1/1000

  13. How many meter is centimeter? 1/100 meter Kilo- X1000 Hecto- X100 Deca- X10 Deci- 1/10 Centi- 1/100 Milli- 1/1000

  14. How big is a meter? Width of a Fingernail Thickness of a dime Little more than ½ mile Height of a door handle

  15. How big is 1 millimeter? Width of a Fingernail Thickness of a dime Little more than ½ mile Height of a door handle

  16. How big is 1 centimeter? Width of a Fingernail Thickness of a dime Little more than ½ mile Height of a door handle

  17. How big is 1 kilometer? Width of a Fingernail Thickness of a dime Little more than ½ mile Height of a door handle

  18. How do we convert from Centimeter to Decimeter? For every step upward on the chart you are dividing by 10 or moving the decimal one place to the left.. 10 ? 100 Centimeter = _____ Decimeter

  19. How do we convert from Kilometer to Meter? For every step downward on the chart you are multiplying by 10 or moving one place value to the right. 100,000 ? 100 Kilometer = _________ Meter

  20. The sun is about 150,000,000,000 meters from earth • What is another way to write the same number without writing all the zeros? • Power or 10 • 15 X 10 meters ? 10

  21. Powers of 10 103= 1000 100 102= 10 101= 100= 1 .1 10-1= 10-2= .01 10-3= .001

  22. Why should we use the metric system or System International? • All the countries around the world including United States uses the metric system • Its easier to divide or multiply by 10 than by 12 or 5280 (i.e. English System)

  23. Lab Safety Poster p.686 • Pick one symbol and create a poster about it • You can draw something more creative than the symbol which represents the safety precaution that you are drawing about.
