1. Measurement In science, the Metric system is used. It is a universal measurement system based on multiples of 10. This makes conversions from one unit to another much easier.

2. Measurement Musts Use the right basic unit Measure with the right accuracy Estimate one place ALWAYS write your units

3. METRIC M K H Dk BASE d c m u M= MegaMeterd= Deci K= KiloLiterc= Centi H=HectoGramm= Milli Dk= Dekau= Micro

4. Basic Units Volume = liters (L) Length = meters (m) Mass = grams (g)

5. Accuracy Measure using the lab equipment that gives you the most accuracy – Ex: beaker vs. graduated cylinder

6. Estimating Always estimate one place past the accuracy of a measuring device. Ex: The smallest unit on this ruler is millimeters (mm). We would measure to the millimeter, and estimate to the 1/10ths place

7. How long (cm)? 0 1 2 3 4

8. How long (cm)? 0 1 2 3 4

9. Estimate for more accuracy 0 1 2 3 4

10. How long (cm)? 0 1 2 3 4

11. How long (cm)? 0 1 2 3 4

12. Graduated Cylinders Measure to the bottom of the meniscus

13. How much? 50 40 30

14. How much? 50 * Read the bottom of the meniscus * Estimate one place 40 30

15. Conversion of Temperatures Fahrenheit to Celsius: C=(F-32)X 5/9 Celsius to Fahrenheit: F=Cx9/5+32
