The Periodic Table The periodic table shows us how two or more elements react to one another. The elements are listed by the number of outer shells or energy levels it has. Each column represents the number of Valance electrons are given, valence electrons predict the way two elements will react to each other. The closer an element is to the bottom left corner, the more electrons that element gives. The closer to the top right the more the electrons they will take. |
For a classroom experiment we decided to make rocket motors just as a demo of the rocket project. We started with a small piece of PVC pipe which we covered one end with masking tape. To start we heated a hot plate to 204℉ and set a beaker onto it, we mixed sorbitol and potassium nitrate and heated it until it melted together and was a soupy consistency, this was the liquid rocket fuel. Once it was at the consistency that was required we poured it into the PVC and let it dry, it solidified very quickly. We were given concrete to seal off the other end. We let this stand for two day to make sure it was dry before testing it out. It worked!
Looking back:
I was really excited to do this project because it gave me a demo of the rocket project. I originally wanted to do the rocket project originally but I decided to work on independent projects instead because it gave me more options. I really want to be able to work with other people and find new projects to work on.
Looking forward:
I plan on moving tables where there's room for the next class wide project . For my next project I need plan to work on more of the core concepts for this class. Over all I am going to continue doing projects by myself.
Looking inward:
The rocket motor worked really well. It could have taken off but it was held in place. The rocket kept burning until there was not anymore fuel in the pipe because there were not air bubbles.
Looking beyond:
As the solid fuel was burning the pipe there was an increase in pressure, the whole that we drilled into the motor allowed some of that pressure to escape, this would have launched the rocket. The pressure is released downwards and it would have taken off if it wasn't held in place.
