Over the past several weeks, our group has been working on a project focused on thermochemistry. The purpose of the project was to convert energy forms from one to another. Once we understood how to convert energy, we used the energy to provide power to a device. Our group used the energy to power a motor, turning a music box. Generating enough power to turn the motor was the biggest issue.
We chose to make a music box, however our music box was lost or stolen and we had to find a new end product. We switched to a musical card and attempted to power it with the energy from different fruits. The fruits act as energy conductors and we put copper and zinc in them to connect the negative and positive ends.
Below is the Proof of Efficacy, which explains how we made decisions for our project and issues we arrived upon. It also has photos and a blueprint.

Concepts:
Joules: measurement of energy
Delta G: Change of in heat of a reaction.
Entropy: randomness of a system
Enthalpy: amount of energy absorbed.
Electrons: Source of electricity when they are in movement.
- Important when deciding on what tools would be best to create the energy for our device.
Acids and Bases: Acids have a lower pH and are more acidic. Bases have a higher pH and are less acidic.
- Together they can help pass electricity through the wires to create power for our device.
Reflection:
Overall, this project was fun to create and I enjoyed working with my group. However, due to our music box being misplaced a few days before we were supposed to present, it made it hard to create a good end product.
I feel that our group could have focused more on time management and testing. If we had done more testing in the beginning, we could have had more data and done more trials. Our group was easily distracted and also got discouraged after the disappearance of our music box. However, prior to the disappearance we all were pretty focused and excited to make the music box work.
Our group worked well as a team and everyone contributed. Everyone in the group brought materials to make the project work. We also all wanted to make it work and tried hard to get enough energy to power the device.
After the completion of the project, I feel that it was a fun and interesting project and the purpose was intriguing. We had to apply our knowledge from chemistry and how energy is transferred to a project, making the information fun to learn.
