For this lab we decided to create a type of rocket motor from stuff you can find in a classroom. We made it more into a chemical reaction. We used sugar and potassium nitrate to create a solid fuel for the rocket.
For this lab we had to use a piece of wood about the size of a straw and wrapped it with a piece of paper so it could become the fuel container. We used take to make is secure, and then removed the piece of wood to have an entry for the fuel. We used the wood to have a type of measurement, like a guide for the fuel on how much we used.
We used tin foil to create a pop cap on the top and to seal the bottom. We used this cap to seal the rocket's body so there wasn't a gap that would let the gas escape and cause the rocket to not shoot up but instead stay in place. We used potassium nitrate and sugar mixed at a 38:13 ratio to create the fuel for the bottle rocket. After getting fuel put into It we sealed the caps on it made made sure they were put on tight because we don't want any gaps!!!
We drilled a hole in the bottom to insert the fuse. The fuse provided a time delay for the energy to the point of lighting to the fuel chamber. We used a wooden stick as a holder so it could stand on its self while the fuse went off.
Our rocket did not end up working at the end, It could of been during the time when we constructed it or when we were having trouble putting the fuse in.
The sugar and potassium nitrate fuel created an outward force that pressures on the hole where the fuse was put into the rocket. This hole in the rocket allowed for the pressure to build up within the fuel chamber and be released with a force that was able to lift the rocket. Reacting to the fuse giving an energy to ignite the fuel to give the rocket that push to succeed. Which ours did not get that extra push.
Our rocket did not meet our goals we had for it. Something must of went wrong when we were constructing it, maybe we didn't tape all of it but I don't think that was the reason. It was probably when we packed the fuel in it and putting the top on it. We probably let some air in it while trying to put on the top and it wasn't fully covered. This creates entry and making the rocket not be pressured together.
Jake and I worked on this lab together we first created two separate rockets just to have our own but at the end we decided to use mine when it came to add fuel. Jake and I had a great time creating this we took turns putting everything together making sure all our parts were put together and took turns trying to screw the fuse in.
If I had to re due this lab I would do everything the same up till the point where the fuel comes in with the caps and make sure i'm doing that correctly and how much we should really add to the rocket to have a good lift off when ready. Also creating the holes small so more pressure gets put into it to create more then we had. Make sure the foil is not stretched and created into a huge whole because of trying to jam the fuse in.
For this lab I really liked the fact that we basically got to build everything yourself and be learning while we go. What I mean is learning about ratios so we could use them for how much fuel we needed to use for our rocket. I liked having a partner during this because I had someone critique my work and have ideas to give while we go.
