bp technology challenge

For the bp technology challenge in my group there is Amelia and Sophia. Our first challenge on Wednesday was to make something out of six bamboo stakes , a long piece of string and some other materials and it had to be able to acuritlay calculate the strength of the wind. On Thursday we went into room four and  did a challenge called raise the flag. On Tuesday we did the marble run in rm 6 with Mr brown. For the marble  run challenge we had to make a marble run the point was to make the marble take as much time to reach the bottom.
