146 1/27/15 Tues. L.T.: I can write a 4 pt. conclusion on my Fan vs. Mousetrap Car Lab and write a hypothesis and procedure for our new Q. DO NOW: How many points does this conclusion get and why? The fan got 0.21 and the MT got 0.77. The fan was faster. ………………… Reflection: Was I able to accurately report out my results in a full 4 pt conclusion? Did I make a prediction about my car’s motion in a 3 part hypothesis? Do I have all 3 variables, set-up description, and logical steps in my procedure? 147 Title: Constant Speed or Acceleration? 4 pt. conclusion written here ……………………… Q: Over the course 2 meters, does your fan or MT car ever reach constant speed or is it always accelerating? Hyp: Procedure: CV: MV: RV: Diagram: 1. 2. 3. Fan 0.21 met/s MT 0.77 met/s Free Seating (with a price): I suggest you choose wisely because I am studying you... Tuesday, Jan. 27th

4 pt. conclusion Conclusive statement -Answer the Q -State whether the hypothesis/prediction was correct Supporting data -give 2 piece of data Always use highest and lowest and averages if given (specific numbers) Explanatory language -use supporting data to answer the question -make a mathematical comparison to support your answer 4 pt. conclusion

Q: Over the course 2 meters, does your fan or MT car ever reach constant speed or is it always accelerating? Hypothesis: If I race my _______car over 2 meters, then it will __________________, because ______________________ Hypothesis

Variables: CVs: surface (sweep each time), distance of entire track and each section, how to release each car, starting and stopping timer at each section accurately MV: type of car RV: time it takes car to travel each section (.50 meters) Set-Up: Instructions or diagram explaining how to set up lab Steps: What do you need to do 1st to start collecting data? What do we do 2nd? Be specific! Procedure
