Method
    I will use foam darts, mark out distances on the ground, and see how far the dart goes at different launch angles. I will have an assistant to tell me at how far each of the darts lands. I will adjust the angle a few times to see what angle produces the best results. I will also try firing at least 6 darts each time. I will also try to minimize air resistance or movement of air by turning off the air conditioning, and closing doors so no air will come in. Air currents could possibly change the results. I think that this will have to be done in the gym as a few trial darts have run into either the ceiling or the wall of my house.

Trimester Two

I also used these blocks to make sure that the support system was always at the same angle. I mixed and matched to get the various angles.

45  30
These two blocks make 45 degrees.                         This block is 30 degrees.
60
These two blocks make up 60 degrees.
