For this lab we created rocket motors. Before beginning this lab we watched a video about the periodic table and the chemistry behind rocket. While watching this video they showed us rocket like reactions happening when blowing up cars. The rocket was made out of potassium nitrate and sugar. This project was very and similar to the smoke bomb project. In fact our smoke bomb project was much stronger than the rocket. Once filled we put a cement filling to help it set and stay inside. |
Reflection
Looking back what happened?
The results we got from this lab were great. We Andrew lit our motor and burned very intense and a big smoke cloud was created. It also had a very loud sssss noise.
Results on a molecular level?
My results on a molecular level were very cool. When dried our rocket motor looked like cement and was very hard. It was cool how when it burned there was almost nothing left except for like a black substance on the floor. Which possibly might have been carbon.
What contributed to getting desirable or undesirable results?
Well we did get desirable results and somethings that I think might have contributed to getting desirable results was not moving or shaking our engine around which might of disturbed the mixture while it was setting. I think I performed well on this experiment because I have experience with this mixture, earlier this section I created a smoke bomb which called for the same mixture.
Looking Outward Collaboration?
I worked with Nayeli, Marco, and Jiapsi for this project. Marco, Nayeli, and we all have experience with this mixture so we were able to explain to jiapsi what is happening with motor.
What next?
If I were to do this project again I would definitely create a rocket that we could launch, using that motor. I have done experiments in this category a twice and I think that I have enough experience to finally launch a rocket with that type of motor.
Take aways?
I learned that the more potassium nitrate there is the more intense it will burn so if I were to make a rocket like i said earlier I would definitley know how the mixture can affect how fast or high the rocket will go.
