  1. Do Now 3 minutes! • Estimate the length of the leaf using ruler A. • Estimate the length of the leaf using ruler B. • Which ruler has higher precision? • Which ruler has higher uncertaintyor chance for error? A B

  2. Homework :D • Do Now • Physics to Go TURN IT IN

  3. Shout Out!

  4. Homecoming Spirit Days • Tuesday– Superhero day • Wednesday– Way back “when”sday • Thursday– Picture Day: dress to impress • Friday– Golda Meir spirit day

  5. Objectives 1-2 • Agenda • Do Now 5 • Reflecting 5 • PEQ 10 • WDYT Now? 10 • Quiz 10 • Preparing 10 • WDY See? Think? We are learning… • All measurements have uncertainties or random errors • Repeated measurements can vary in accuracy and precision • Random errors can be attributed to the measurement and/or the measuring instrument We will be successful when we can… • 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

  6. Reflecting (page 31)

  7. Preparing 1-2 6 minutes! • Mention how uncertainties are a part of safe driving • Explain why driving 31 mi/h in a 30 mi/h zone does or does not warrant a ticket • If you do not think that 31 mi/h deserves a ticket, you will need to explain what speed should get a ticket and why

  8. P.E.Q. (page 31) 8 minutes!

  9. WDY Think Now? 6 minutes! • Two students measure the length of the same object. One reports a length of 3 m, the other reports a length of 10 m. Has one of them made a mistake? • If the students reported measurements of 3 m and 3.01 m, do you think one of them has made a mistake? • How can you reduce errors? • Random error • Systematic error • Accuracy • Precision

  10. Quiz 1-2 8 minutes!

  11. Preparing 1-1 6 minutes! • Describe how knowing your own reaction time can help you be a safer driver.

  12. WDY See? (page 34)

  13. WDY Think? (page 34) In a rear-end collision, usually the driver who strikes a vehicle from behind is legally at fault. • What is a safe following distance between your automobile and the vehicle in front of you? • How do you decide what a safe following distance is?
