On 30th of may the class and I were working on aerodynamics first we needed to find the the center of math what we did for that we tied a piece of string around the rockets, and then we had to try and put the string in the right place so that when we lifted the rocket it would balance when we found the right place we had mark it, after that we had to trace our rockets on to some cardboard when we finished tracing the rockets we had to cut it out, then we had to get a ruler, and with that ruler we had to try balance the cardboard on the ruler when we finally got the cardboard to balance on the ruler we were finished.
