Thermochemistry - You have the power!
Evidence of Work:
In this final project our goal was to create a potential energy transfer device, in order to demonstrate how we can convert chemical energy into another useful form of energy. My energy transfer device was a homemade model turbine which I made with simple materials at home, and a dc motor. As for measuring the amount of energy produced, I ran 3 trials with different wind speeds and found the average voltages of each trial with a voltmeter. With my voltage results being small, it only made sense with my models design, and with future modifications it will be able to run more efficiently and conduct more energy. I created a, "Proof of Efficiency Document" which has all the information on my energy transfer device. It includes; the steps to making my device, the energy transfers, the molecular blueprints, images of the device, thorough descriptions of the device and data, as well as some other details.
Content Vocabulary:
Chemical Energy: The potential of a chemical substance to chemically react and transform into another substance. (examples; batteries, gasoline, food, etc.)
Radiant Energy: The energy of electromagnetic and gravitational radiation. (examples; x-rays, gamma rays, heat from fire, etc.)
Nuclear Energy: The energy released during nuclear fission. (example; nuclear power plant, nuclear weapons, electricity, etc.)
Thermal Energy: The kinetic energy associated with motions of molecules of a material or object. (examples; heat from temperature, sunlight, etc.)
Electrical Energy: The electric potential or kinetic energy that's been converted. (examples; light bulbs, batteries, lightning, etc.)
Mechanical Energy: The sum of kinetic and potential energy in a system. (examples; hammer, cycling, wind mill, etc.)
Reflection:
Due to this being an individual project there was no collaboration, communication, or character elements to it however there still are graduate profile characteristics to reflect upon. I personally choose a wind turbine to be more on the creative end, I wanted to do a different project than the rest of the class majority. I felt that I utilized my Critical Thinking with that, especially when it came to building my wind turbine, since I had limited materials at home. However, my downfall in the Critical Thinking category is with the simplicity of my project, I chose a simple measurement for my energy output with a voltmeter, despite having the creative option of powering a household item that runs on power, for example an LED light or calculator. I did manage my time well and for the most part got my energy transfer device completed as well as my "Proof Of Efficiency Document," which falls under the Conscientious Learning category, however I did start my project later than most which caused a limit in my materials for my project. But overall, I think I did well on this project and I had fun with it.
