  1. AR Book ScienceStarters Sheet Agenda Comp. Book (Science) 1. Please have these Items on your desk. Monday, August 13th Day 2 • Science Starter: • Three vocabulary words. • Write the word on the front of the index card and the definition on the back with a simple picture. This picture is used to trigger your memory into remembering the definition! • Use 3 separate cards

  2. Vocabulary words • Meter-Basic metric unit of distance or length. Symbol (m) • Liter- Basic metric unit of volume. Symbol (L) • Gram- Basic metric unit of mass. Symbol (g)

  3. Variables Quiz • Correct heading at the top of the paper. • Clearly circle your answer. • Read your book until everyone is done. I will tell you when they are done.

  5. Metric Conversions Ladder Method T. Trimpe 2008 http://sciencespot.net/

  6. 1 2 3 MetersLitersGrams How do you use the “ladder” method? 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction. Starting Point Ending Point __. __. __. 2 3 1 Ladder Method KILO1000Units HECTO100Units DEKA10Units DECI0.1Unit CENTI0.01Unit MILLI0.001Unit 4 km = _________ m How many jumps does it take? 4. = 4000 m

  7. BASIC UNITS (page 10) OF THE METRIC SYSTEM • The meter(m) is the base unit of length. • The gram(g) is the base unit of mass. • The liter (L)is the base unit of volume.(L)

  10. Converting Units To convert from one unit to another is like following directions on a map. Which way? Left or Right?

  11. Going Left??? When going from a smaller unit to a larger unit, you move Left on the map and the decimal moves to the LEFT .

  12. Going Right??? When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT .

  13. Practice Time 4.5 m = ? cm

  14. What to do first in the problem 4.5 m = __ cm ? Start at Meters and move to the Right to Centimeters. Decimal place moves to the RIGHT two spaces. . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 4.5

  15. As you move the decimal you will need to add zeros. . 4 . 5 0

  16. Is this your Final Answer? 4.5 m = 450 cm

  17. Let’s do another one! 6.6 liters = _____ mL

  18. What to do first in the problem 6.6 L = __ mL ? Start at Liters and move to the Right to Millileters. Decimal place moves to the RIGHT three spaces. . . . . Kilo Hecto Deka Basic Unit Deci Centi Milli 6.6

  19. Check your answer! 6.6 liters = 6,600 mL
