Design+Challenge

__Statement:__ //The purpose of my design challenge was to accomplish electrolysis and set off my rocket. This design challenge was meant to be quite simple and straightforward, but it turned out to be very confusing and at times, quite difficult to do.
 * Design Challenge:

__Reflection:__ // // My design challenge was quite successful. I managed to launch my rocket and it flew quite high. According to the instructions of the Estes Hydrogen Rocket, the first thing I had to do was put in 9 'D' alkaline batteries into the launch pad. I then had to create the Fuel Generating Solution by using water and crystalline. I then poured the crystalline into the fuel generator and turned on the 'on' switch. Little did I know, the launch pad was somehow broken and the LED light wouldn't turn on. Had the LED light turned on, the Fuel Generator would have started electrolysis and then i would have been able to launch the rocket. Since the launch pad was broken, I got Mr. Happer's assistance to try to locate the problem inside the launch pad. I spent about a class and a half trying to find where there circuit was broken, but it was a difficult task to do because there was a lot of glue covering the wires, so I had trouble measuring the currents and the voltages. Once Mr. Happer and I realized that the launch pad was broken beyond our repair; Mr. Happer suggested that I use the Generator Box for the rocket. Using the generator box would completely skip the launch pad, and the volts would go directly to the rocket. With the generator box, I managed to get bubbles inside the fuel generator. The bubbles meant that the hydrogen and oxygen atoms were splitting up and that the electrolysis was working. Once I realized the bubbles worked, I had to figure out how to work the filament. The filament would spark, which would ignite the hydrogen and the rocket would launch. Using the generator box, I accidently set my rocket off inside the class, but luckily, it only bounced off the ceiling and landed on the floor, and didn't hurt anybody. Once this happened, I knew my rocket was a success, and now the only thing i had to do was set it off outside. I redid the electrolysis process and then went outside to launch it. Lighting the filament outside was harder to do, because I used batteries instead of the generator box. It took me about 10 minutes outside to successfully launch my rocket, but I managed to do it and my design challenge was success. //

8-10 Terms Explaining:

1) __Acceleration__: Acceleration is the rate of change of velocity. When my rocket was launched, it shot up into the air, accelerating while doing so. But after a specific height, it started to decelerate and then turn back to the ground, and the accelerated down to the floor. 2) __Net Forc__e: Acceleration is directly proportional to net force. The force of the hydrogen escaping the fuel generator caused the rocket to accelerate, and gravity caused the rocket to accelerate back down. 3) __Potential Energy:__is energy an object has because of its position. The rocket had a lot of potential energy because it was sitting on the hydrogen that would set it off. 5) __Renewable Source__: the energy I used for my hydrogen rocket is renewable and reusable. After the rocket is launched, the hydrogen and oxygen forge back together and it can be re used infinite amount of times. 6) __Voltage__: is potential energy. I used voltage as my energy for electrolysis. 7) __Current__: is the flow of electrons. I used currents to measure if the launch pad was working, to see if the electrons were flowing through the wires. 8) __Momentum__: is inertia in motion. My rocket used the momentum of the blast to fly up in the air, but the momentum soon ran out and the rocket fell back to the ground.

Pictures: **

1) Hydrogen Rocket. This is the rocket that actually flies up into the air.

2)

3) Crystalline Solution Maker. You put water and the crystalline solution inside and shake it.

4) Ignition Chamber. Oxygen and hydrogen molecules flow into this chamber and are ignited to launch the rocket.

5) Launch Tube. The ignited hydrogen and oxygen escape through the launch tube and gives the hydrogen rocket the force to shot up.

6**)** Fuel Generator. Converts tap water into hydrogen rocket fuel by passing an electrical current though a special fabric to bust water molecules into oxygen and hydrogen that become the rocket fuel. This is called electrolysis.
