WEDNESDAY, JAN. 28 TH 148 1/28/15 Wed. L.T.: I can write logical steps to my procedure and follow them to gather my data. DO NOW: What needs to be changed about these logical steps? 1.Get people in place. 2.Start the car. 3.Time the car. 4.Do this 3 times Reflection: Are my logical steps detailed, written in chronological order, and clearly instruct on how to gather data? Was I able to work collaboratively with my team and collect data for my car type? Is my data table fully filled out? 149 Title: Constant Speed or Acceleration? 2 Procedure Logical steps: ……………………………………………….

JOBS  Team Leader (1) : does Ms. Kim’s job of organizing and orchestrating the data collecting. Knows everyone’s jobs by heart and has leadership like a leader, not a boss.  Timer (4-8) : accurately times the car passing through their section; reports out to calculator or Ms. Kim their data  Calculator (4*) : in the case of multiple timers, calculator must gather data and calculate average and report to Ms. Kim  Mechanic (1) : must keep car tuned up and ready to go at all times. Only one to handle supplies. Must be patient and quick. Releases car at Team Leader’s signal.  Mechanic’s Help (1*) : receives the car on the other end and assists Mechanic with any repairs; sweeps before each trial  *if we have enough people – these jobs get filled in last
