  26. 26. My Feedback Sheet G4IA Assessment sheet 11/3/2008 Student: Gonzales, Jose Investigation: Rocket Design Lab Time: 2Hrs Date(s): 08/01/08 Design General comments Ringo Dingrando 2 Defining the problem and selecting variables You formulated a research question and identified the relevant variables. Great idea to change the center of gravity of the rocket! No one else thought of that! Great sketch graph to help visualize your hypothesis. 1 Controlling variables You do not effectively control variables. By adding extra tape to the tail every time, you WILL change the center of mass, but you are ALSO changing the very important variable of rocket mass. 1 Describing a method for collection of data :) Excellent drawing. You do not state the increments of your independent variable measurements. You do not list the range of your measurements. It is quite clear how and where you intend to add the mass, but how much tape each time? What will be your maximum amount? What about multiple trials? 4 This criteria is only addressed This grade will not appear on the PSOW You are making similar mistakes as you did on previous labs. Please see the feedback on previous labs before you do your next one!
