Evidence of Work
At the beginning of the project our teacher, Mrs. Vogl gave of the overall goal of the project… to create a system or contraption that transfers energy of one type into another type of energy. Our group, Nick, Reema, Suyash, and I decided to construct a lemon battery to in the end power a fan. As I stated before we have to use different types of energy so the types of energy we used were kinetic, chemical, electrical, and thermal energy. To give you a better understanding of the different types of energy I will now define them. Kinetic energy is the energy an object possesses due to its motion, and thermal energy is the energy that comes from heat from the movement of tiny particles within an object. Chemical energy is defined as energy stored in the bonds of chemical compounds, like atoms and molecules. Electrical energy is a form of energy resulting from the electrical attraction or repulsion between charged particles.

Chemical energy- energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place.
Electrical energy- a form of energy resulting from the electrical attraction or repulsion between charged particles.
Kinetic energy- the energy an object possesses due to its motion.
Thermal energy- the energy that comes from heat from the movement of tiny particles within an object. When an object contains kinetic energy and is on Earth, there is always friction which causes some energy to be lost to thermal energy
Oxidation reaction- a type of chemical reaction that involves a transfer of electrons between two species. In our lemon battery, the zinc anode dissolves into the liquid electrolyte in the lemon, leaving two electrons behind.
Cathode- the positively charged electrode of an electrical device, such as a primary cell, that supplies current.
Electron- a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. The flow of electrons from the lemon battery through the alligator clips produced the voltage we needed to power an LED, but there was not enough electrons flowing at a fast enough rate to power the motor.
Current- a flow of electric charge (measured in Amps). In electric circuits this charge is often carried by electrons moving through a wire.
Voltage- an electromotive force or potential difference expressed in volts (V). We were able to generate a maximum of 4.05 V, but it was still not enough.

Reflection:
This was a very enjoyable project for me, I really enjoyed the project overall. I enjoy these types of projects where its almost like a puzzle. Where you have to figure out a way to convert one type of energy to another. Our group had very good collaboration, we all did something to contribute at all times. Weather it was Suyash who made the blades, or nick who bought lemons, we all did something to contribute. We collaborated well. Another thing that we did well was we communicated with each other very nicely. We created a group chat which included all of us and we communicated very nicely after school. Im very happy that we communicated well because it made it so much easier to designate tasks outside of the classroom.
With all groups there are always going to be some ways we can improve. I feel like we took too much time figuring out what to do in the beginning. There are a variety of reasons that led to starting our building process late. At the beginning we were off task a little bit. We were mostly talking about the SAT, and all of our ap tests. During this time we should have been critical thinking and trying to figure out how to transfer one type of energy to another. Another thing that didn't go well was in the end we all got a little frustrated. Our project didn't end up working in the end, we never were able to power the fan. We tried so many times, and we got the same result each time, no power... failure. So you can see we got a little frustrated with each other at the end because whatever we tried.. It didn't work. Next time we need to keep our composure throughout and remember that we are a TEAM and work as such throughout all.
