  5. A measurement system providesquantitativedata • Quantitative means a number is used • Qualitative data: • It turned red • It is cold • It started steaming

  6. M e a s u r e m e n t S y s t e m • W h a t i s a m e a s u r e m e n t “ s t a n d a r d” ?

  7. S t a n d a r d • Allows scientists to compare results • Never varies

  10. Conversions • King Henry Died ByDrinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Problem – Convert 22cm to meters.

  11. Conversions • King Henry Died By Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit * Start at CENTI

  12. Conversions • King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit * 2 1 Move 2 Spaces to the left – to base unit (which in this case is METER)

  13. Conversions • King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Each move to the left represents a division by 10. DIVIDE 22 by 10 twice (or divide once by 100)……. 22 divided by 100 = 0.22 22cm=0.22m

  14. Conversions • King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit If the problem requires you to move to the RIGHT then you MULTIPLY by 10 as many times as you moved to the right

  15. Make a Chart in Your Notes 5 Columns 7 Rows • Make the spaces big enough to write in

  16. Insert Headings for the Columns

  17. Insert Row Titles:

  18. What is the base unit used when measuring length?

  19. A DIRECT MESUREMENT is taken when the measurement can be read directly off the tool – no math is required. Is the measurement of length a DIRECT or an Indirect measurement?

  20. No Formula Required!So, Leave the Formula Cell Blank. What Tool is used to measure length?

  21. As I Demonstrate the Use of the Tools – Fill in Your Chart As We Go

  22. There is a lab set up at the rear of the room • Wait for further instructions
