1. The Metric System PowerPoint Presentation

2. The Metric System In Science, we use the metric system. It is based on a scale of 10. Every measurement is increased or decreased by a factor of 10. The whole world (except the U.S., Liberia, and Burma) uses the metric system.

3. Measuring in Class We will measure mostly. Mass Volume Length Temperature

4. Mass Mass measures how much stuff is in something. Basic unit is the gram (g) We use a balance (scale) to find mass!

5. Volume Volume is how much space something takes up. The basic unit for volume is the Liter (L) We use a graduated cylinder to find volume.

6. Length & Distance Length is how long something is. Distance measures how far something is. The basic unit for length is the meter (m) We use a ruler, meterstick, or a trundle to determine distance.

7. Temperature Temperature measures how hot or cold something is. The unit for temperature is degrees Celsius. We use a thermometer to measure temperature

8. KILO 1000 Units HECTO 100 Units DEKA 10 Units DECI 0.1 Unit CENTI 0.01 Unit MILLI 0.001 Unit Meters Liters Grams Ladder Method 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 1 2 3 How many jumps does it take? Starting Point Ending Point 4. 1 __. 2 3 = 4000 m

9. Try these conversions using the ladder method. 1000 mg = _______ g 1 L = _______ mL160 cm = _______ mm 14 km = _______ m109 g = _______ kg 250 m = _______ km Conversion Practice Compare using, or =. 56 cm 6 m 7 g 698 mg
