Journal Entry

Tiffany Journal-personally I would have to say that this over all project was interesting. Due to the over sized-side hole of the cannon, it back fired and the cannon itself didn't work as the group planned. As you can see in the video I chose to be the one to light the cannon. Knowing that I was scared i think that if i would have put the fired more into the hole at least the ball would have release from the cannon. Meanwhile things didn't work out the way the group planned. Thanks to my teammates the cannon project ended on a good note.

Cannon Creation

Task:

1. Obtain a list of materials:

2 tennis ball cans with tops

12 inch strip of duct tape

1 pair of scissors
2. Create a graphic organizer by designing on paper a model of your cannon.

3. Construct the cannon – *and remember to include an opening for the ignited wood splint.

4. Record each step of your construction. For this part, you should to take digital photos /video to document your construction so that you may incorporate visuals in your written and oral explanation.

Hypothesis:

Using Boyle's Law, our team decided that with a smaller volume, the nerf ball would laucher @ least 5 feet.

Procedure:

1. First we drew three different shapes after researching the way that cannons were built.

2. Then after measuring 12 inches of tape, we began to cut out the cannon the way that we imagine would work.

3. Afterwards we added the angle of approximately 45 degrees just to give it a more of a angle to fire.

Conclusion:

Because of all the pressure that built up, our cannon was unfortunately unable to fire at its full potiential. We discover that if we would have not allow for the pressure to escape in a different area then the nerf ball would have exceeded 5 feet. During the experiment our physical cannon creation maneuvered backwards.

Journsl Entry

Lillian Journal: During this experiment I have learned that although your pressure may build up you should allow enough space for the pressure to evenly fill the container therefore your should measure the area that you want to cut out of the side so that there isn't too much of the pressure escaping from the container. I expected for the cannon to fire @ least five feet but was disappointed because our cannon didnt go anywhere. Although it didn't our cannonmoved backwards.

Reflections of OUR Cannon

On the day of our launching, we discovered that our project would have been one of the top, except for the flaw of having too large of a whole on the side, which allowed the pressure to escape from out of the structure. We also didn’t recognize the fact that we needed a little more space in order for the pressure to evenly spread throughout the cannon therefore it would have been able to shoot to its full potential.

Day 2

Today my group has revised our thoughts and have begun to construction the actual product. We have predicted that if we have the cannon shooting upward and still allowing pressure to build up then there is no reason that our cannon should not project far as it possibly will allow.

Day 1

Today as our group embraced on this project we began to make paper designs of what our cannon may look like. We checked the relation between Pressure and Temperature, then the relation between Temperature and Volume, and last Volume and Pressure. There was also the research of finding the temperature of how hot we need the the flame to be.

INFORMATION

• Although first used in China, they eventually migrated over the world, mostly for the use of a weapon during wartime. Cannons are a large tubular-shape firearms that may use gunpowder to fire a heavy projectile over a certain distance of land.

• Ctesibius of Alexandria was a Greek inventor and mathematician located in Alexandria, Ptolemaic Egypt, that created a form of a committee operated by compressed air, before the time of 200 B.C.

• Eventually, the barrels of paper and bamboo were replaced with metal, and named the “Huo Tong” meaning fire-tube or gun.
