2. Friday, Feb. 6 th 162 2/6/15 Fri. L.T: I can build my car, gather time data, and calculate average speed to determine whether my car is faster than the stock car over 2 meters. DO NOW: science notebook check ……………………………. Reflection: With my partner, did I successfully build my car, gather time data, and calculate avg. speed? With my partner did we determine whether our car was faster or slower than the stock car? 163 Title: K’Nex Car Redesign 2 SNB Check taped in here Data: ………….. Analysis: Did my car beat the stock car’s avg. speed? If so, by how much? If not, by how much? What do you think attributed the most to your car’s success or defeat? What are some ideas you would try given another chance? Why? CarT1T2T3Avg. Time Avg. Speed

3. Order of Events 1. Blueprints: (Leader: Engineer A) - Wednesday - rough drafts in everyone’s SNBs - official blueprints made and approved by CEO 2. Building: (Leader: Engineer B) – Thursday/Friday - parts collected and built according to official blueprints 3. Data Collection: (Leader: Engineer C) – Thursday/Friday - car taken to track and tested over 2 meter track for 3 trials - calculations made to determine avg. speed. - discussion and decisions made of how to improve speed even more

4. Friday’s schedule If you are on schedule, this is today’s timeline: SNB Check 10 mins. Building your car: 25 mins Running time trials on your car: 15 mins Analysis: 10 mins Clean up/Reflection: 7 mins

5. Jobs Everyone: - rough draft blueprints in SNB - inputs idea of how to redesign car Engineer A: - master blueprints (main person who write and draws on main blueprints with other Engineers’ input. Also makes executive decisions if there are arguments.) Engineer B: - master builder (person in charge of building with the help of other Engineers. Does not mean that they are the only ones that touch materials!) Also gathers materials. Engineer C: - master data collector (the leader who is responsible for collecting data. Orchestrates who does what job and how to keep CVs controlled. Has official record of data in their SNB to share with others) Other jobs that may be needed: massing objects, getting approval from CEO, gathering tape, fixing fan, MT, sweeping, calculating speed, timing, etc.
