  1. TOPIC: Measurement Aim: Explain can we convert measurements? Do Now: Identify the units used to measure the following: HW: Ditto – Density (on back of your density notes).

  2. Announcements: • Measurement test is rescheduled for Tuesday, October 18th. • Your Scientific Method test will be returned tomorrow to go over it. You will have a Scientific Method Quiz this Tuesday, October 11th. • We will discuss how to do your bibliography for your research on Friday. That will be due on Wednesday, October 12th.

  3. A cube is 1 cm on each side and has a mass of 2 grams. Will it float? • yes • no • The only way to tell is to put it in water. .

  4. Comes BEFORE the unit PREFIX

  5. Kilo = x 1000 1 kilometer (km) = 1 kilogram (kg) = 1 kiloliter (kl) = 1000 meters 1000 grams 1000 liters

  6. Centi = 0.01 1 centimeter = 1 centigram = 0.01 meter 0.01 gram

  7. Milli= 0.001 1 millimeter = 1 milligram = 0.001 meter 0.001 gram

  8. CONVERSIONS KILO (k) HECTO (h) DECA (da) Base (m, L, g) DECI (d) CENTI (c) MILLI (m)

  9. EXAMPLES • 1. 100 mm = ? cm Move 1 to the left 100 mm = 10cm

  10. 2. 34 km = ? m Move 3 to the right 34 km = 34,000 m

  11. 3. 257 cm = ? hm Move 4 to the left 257 cm = 0.0257 hm

  12. Kilo Hecto Deca Meter (base) Deci Centi Milli Kangaroos Hop Down Mountains Drinking Chocolate Milk

  13. Examples: 100m = _____cm 1 0 0 . 2. 34km = ____ m 3 4 . = 10.0cm 0 0 0 = 34000m

  14. Examples: 257cm = _____hm 2 5 7 . = .0257hm 0

  15. Let’s summarize… What do the each of the following prefixes stand for? Kilo Centi Milli What is the order of units on the conversion table? How will you know which way to move the decimal? How will you know how many places to move the decimal?

  16. Review: 21hn = ____d 12cm = ____m .45m = ____ km 6.3da = ____ cm
