For this project we were assigned to design a project that would transfer energy into a final product. Our group decided that we were going to use hydro power and convert it into energy to turn on a light. We brainstormed ideas as to how this would work. Eventually came to this idea of having a turbine that would spin and cause a string to move to rotate a motor and power the light. We decided that in order to get the wheel to spin the fastest we would add bottle caps connected to dowels to catch the water as it is poured on the wheel. After blueprinting our design we went and started our building process. We cut all of our pieces to size and then began to assemble it. After it was complete we ran many tests and solved issues that came up. Eventually we came to our final product and it worked just as we wanted.

Evidence of Work:
This is a picture of our first successful run of our project. We got the light to flicker but was unable to fully turn on. We deducted that this was because there was not a stable flow of energy that would let the light continuously glow.
<--- This is an image of our wheel. We put a dowels in our wheel along with bottle caps to catch the water. We also added ball bearings in our supports to allow the wheel to spin freely.

This is an image of our light and motor. We taped it down to a piece of wood in order to stabilize it. We also added a piece of cardboard so that the string would stay on.
Major Concepts:
Energy Transfer:When a chemical reaction occurs, energy is transferred to or from the surroundings. There is usually a temperature change. For example, when a bonfire burns it transfers heat energy to the surroundings
Mechanical Energy:Mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant
Heat Energy:Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat
Light Energy: Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light contains photons which are minute packets of energy
Energy:Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, helectrical, chemical, nuclear, or other forms.
Reflection:
Overall this project was successful. Although we ran into issues along the way we were able to overcome this and finish our project and get it to work. These obstacles forced us to think and come up with solutions to new problems. Our perseverance and problem solving allowed us to complete this process with success.
I think that during this project we learned a lot about how our group worked. We did a good job in some areas and not as good in others. One of these areas that we succeeded in collaboration. We did a great job of keeping each other accountable and on task. This allowed us to supply each other with feedback that can help us grow and improve on what we struggle with. A second would be our communication. We did a great job of talking through our problems and helping each other figure them out. We were able to make many modifications and solve issues that came up.
While a lot went good for us we also had some room for improvement. One thing was conscience learner. We struggled with our organization and prioritization. This kept us off track and made us struggle to finish on time. We could improve on this by setting deadlines and aiming to meet those. A second thing we could have worked on was critical thinking. We could have applied more constructive arguments. This would have allowed us to expand on our project and understand what each other wanted. We can do this by just sitting down and talking about what improvements we needed.
In conclusion, throughout this project we hit many road bumps. However we persevered and resolved all of our issues. This project allowed us to learn both about the transfers of energy while also teaching us about what we need to improve within ourselve.
