1. Measurement Why Accuracy is Important

2. Oops!

3. History of Measurement History of Measurement for Kids

4. Variables that we directly measure

5. Length Measured with a ruler in metric or English (meters, feet, …) Football Hockey

6. Dressage Arena

7. Micrometer Instrument that measure very small lengths

8. Snowboards are measured in cm’s

9. Laser light Measured in wavelengths (nanometers and micrometers)

10. Mass – how much matter something is made of (Measured in grams and kilograms on a triple beam balance)

11. Time Units are seconds, minutes, hours, …

12. Temperature (Measured in degrees Celsius, Fahrenheit, or Kelvins with a thermometer

13. Weight- is the measure of the force of gravity on an object Units are ounces, pounds, grams

14. Measurements that we derive from other measurements

15. Volume Solids and Liquids X

16. Liquid volumes are measured directly with a variety of containers Beaker Graduated Cylinder Measuring cups ml ounces

17. Other units for measurement you will use this year Force is in Newtons (kg m/s²) Energy is in Joules (kg m²/s²) Momentum is in kg m/s Density is in g/cm³ or g/ml Speed is in m/s Acceleration is in m/s² Hertz (frequency) waves/s

18. Other weird measurement units

19. Altimeter- measures elevation using air pressure changes Flying a plane

20. Air Pressure Units inches of Hg (Mercury)

21. Blood Pressure Cuff Measured in mm of Hg (Mercury)
