Metric Conversions Ladder Method T. Trimpe 2008 http: //sciencespot. net/
How do you use the “ladder” method? 1 st – Determine your starting point. 2 nd – Count the “jumps” to your ending point. 3 rd – Move the decimal the same number of jumps in the same direction. 4 km = _____ m Starting Point Ending Point How many jumps does it take? 4. __. 1 2 . = 4000 m . __ __ 3
Conversion Practice Try these conversions using the ladder method. 1000 mg = _______ g 1 L = _______ m. L 160 cm = _______ mm 14 km = _______ m 109 g = _______ kg 250 m = _______ km
Metric Conversion Challenge Write the correct abbreviation for each metric unit. Kilogram _____ Milliliter _____ Kilometer _____ Millimeter _____ Centimeter _____ Gram _____ Liter _____ Milligram _____ Try these conversions, using the ladder method. 480 cm = _____ m 5. 6 kg = _____ g 8 mm = _____ cm 5. 6 m = _____ cm 120 mg = _____ g
Use your notes from yesterday and answer the following: Compare using <, >, or =. 25) 63 cm 27) 5 g 6 m 508 mg 29) 1, 500 m. L 1. 5 L

DENSITY
Volume The amount of space occupied by an object is called its volume. • V=lxwxh • Water Displacement • Final water level- initial water level= V
Mass -is a measure of the quantity of matter in an object
Density • Density is the mass per unit volume of a material. • You find density by dividing an object’s mass by the object’s volume. • D= M/V
