Science Component

~Hypothesis~
With the Ideas from everyone in our group we think the with the right design and the right angle are cannon will shoot about eight feet out the cannon.

~Cannon Created~
Cannon Construction is not a very easy process, it takes allot of time and work to prepare an actual operating cannon. I’m Lea Cenname and I am in a group with Alex Pender, Tala Khatib, and Jennifer Williams. Each group is given 2 tennis ball containers, a pair of scissors, and one piece of 18 inch tape. Our group has discussed all ideas possible and has concurred on one particular idea. This idea is to cut one of the tennis ball containers twice. This way we can prop up the other with the two pieces of the other container. The following are our steps we used to create our cannon. Steps: 1. Find and Measure angle, 2. Decide what height we want the cannon to be propped at, 3. Once found we must cut the 2nd bottle to fit the standards that were set, 4. Cut the cut bottle to hold the other bottle, 5. Measure with protractor to find the angle, 6. Once found cut again, 7. Tape the small piece of the cut bottle to the uncut bottle, 8. Cut the other piece of the cut bottle to a specific chosen height and angle, 9. Tape that part of the bottle onto the uncut bottle, 10. Finish last minute touch-ups. The hard part of building the cannon was all of our conflicting ideas and shouting them out all at once. It got to the point where we finally had to just sit down be quiet and raise our hands when we wanted to say something. But we got the job done and we were satisfied with our result.

~Experiment Recorded~
Today we launched! But unfortunately our cannon along with everyone else’s, did not shoot the Nerf ball out of it. Our theory on why this happened was based on the theory of Gay Lussac's Law that say temperature is directly proportional to pressure. Today the temperature was lower than we expected which meant that the pressure was low. Since there wasn't enough pressure that built up inside the cannon the Nerf ball did not shoot out of the cannon at all. But we plan to recreate the experiment when the temperature is at a higher degree that way there will be more pressure in the cannon to be built up and hopefully we will get better results.

~Reflection~
If our group were to do anything different I would have to say that we should create a combustion chamber so the pressure could build up enough to send the Nerf ball flying. Of course I don't how well our original design would have worked because of the low temperature of the day resulting in the low pressure inside the cannon.
