  1. Measurement: Errors, Accuracy, and Precision Physics Chapter 1, Section 2

  2. August 13, 2010HW: Physics to Go (PTG)-pg. 32, #6-9 • Do Now (NB pg. 6) • Turn in Current Event • WDYS & WDYT- • TB pg 22 • Success Criteria • Calibrate the length of a stride • Measure a distance by pacing it off and by using a meter stick • Identify sources of error in measurement • Evaluate estimates of measurements as reasonable or unreasonable • Complete various metric conversions • Agenda: • Collect CE • Do Now • 1.2 Measurement: Errors, Accuracy, and Precision • Physics Talk • Metric Mania • Quiz 1.2 • Homework: • PTG, pg. 32, #6-9

  3. Investigate pg. 23-24

  4. August 17, 2010HW: Finish PTG #6-9 • Do Now (below data for 1.2 in notebook): • What is the difference between a systematic error and a random (human) error? • In your groups answer #9 on TB pg. 24 in your notebooks, be prepared to share out • You may use a computer, meter stick or tape measure to help you with the conversions • Agenda: • Do Now • Success Criteria • 1.2 Measurement: Errors, Accuracy, and Precision • Physics Talk • Metric Mania • Quiz 1.2 • Homework: • PTG, pg. 32, #6-9 • Success Criteria • Calibrate the length of a stride • Measure a distance by pacing it off and by using a meter stick • Identify sources of error in measurement • Evaluate estimates of measurements as reasonable or unreasonable • Complete various metric conversions

  5. Physics Talk • What are Random Errors? • Produced by measuring tools and human mistakes • Cannot be corrected by calculations • Can never be eliminated

  6. Physics Talk • What are Systematic Errors? • Can be avoided • Corrected by calculations • Example: If I accidentally measured in inches, when I was supposed to measure in centimeters, I could convert to get the right numbers

  7. Physics Talk • What is accuracy? • What is precision? • How close to an accepted value • Example: Shooting on goal in soccer • Frequency of results • Always hit close to the same spot • Example: Always missing wide right when shooting the ball in soccer

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

  9. August 18, 2010HW:PTG pg. 32 #6-9 • Do Now: In your notebook (below notes) answer the following: • WDYTN? TB Pg. 30 • Reflecting on the Section Challenge: TB pg. 31 • How will what you learned in 1.2 help you with your chapter challenge (pg. 3) • Success Criteria • Calibrate the length of a stride • Measure a distance by pacing it off and by using a meter stick • Identify sources of error in measurement • Evaluate estimates of measurements as reasonable or unreasonable • Complete various metric conversions • Agenda: • Collect Metric Mania • Do Now • Success Criteria • 1.2 Quiz • PTG pg. 32 #6-9
