When building the speaker we used a plastic cup, 2 magnets, magnetic wire, and headphone cables. We wrapped the wire into coils and taped the to the bottom of the cup. We then cut the headphone cable in and stripped about two inches off the end. We wrapped the ends of the magnetic wire around the stripped headphone wires. We then put one magnet on the bottom inside of the cup and on the bottom outside. Plugging in the headphone cable to my phone and playing music. The way this works is the wires that the music from the phone is transferred from the headphones to the coils and the magnets amplify the music thus creating a speaker. Even Though our speaker didn't end up working after multiple tries it was still really fun to make!
14 Cell Powered Homemade Battery
Description: For this battery we used an ice mold then we wrapped wire around each nail and placed them into each cell, making sure that the end of each wire was reaching into the cell next to it . We filled each cell full with vinegar. We then attached the positive volt onto the wire on the left side (anode) and attached the negative volt to the nail on the right side (cathode). The anode then gave electrons to the other nails which followed into the cathode who gained all the electrons at the other end. Which in turn powered our voltage meter.
Rube Goldberg Machine Project
Project Description: For this project we conducted our own rube Goldberg designs that included all six simple machines. Once our designs were complete we began building them. Then we filmed videos of our machine working and edited them to finish off the project.
Project Reflection: Energy) Conservation of energy is energy that cannot be created or destroyed but transferred from one form to another. Whereas energy transfer is energy from one object being transfer to another object. Conservation of energy is shown in my rube where the marbles are going down the ramp they are creating kinetic energy. Once they reach the pulley system the energy changes to potential energy. Mechanics) The six simple machines are the inclined plane. The lever, wedge, wheel and axle, pulley, and screw. The six simple machines are important because they transform energy into work. The screw in my RGM is the spiral, the pulley is what catches the marbles at the end of the ramp where the weight then triggers the lever to make the golf ball drop down onto the second ramp. The wedge is what is holding the phone, but I was not able to incorporate the wheel and axle into my machine. My challenge step was also my spiral I chose the spiral so that I could incorporate both a challenge step and a screw in one step. Learning and Growth) My biggest challenge throughout this project was building my RGM and making sure it worked to the best of my ability. I overcame this by refining parts of my machine and editing my video so that each step ran together because I couldn't make my machine work in one round.
Photographs of Physics Project
Project Description: For the photographs of the physics project we learned about reflection,waves,refraction,color, light waves, and light emission. Then for our final product we were supposed to take a photograph that pertains to any of the topics above. We constructed a camera obscure at school. We also constructed a pinhole camera at home and developed photographs with it.
Project Reflection: My greatest strength throughout this project was persevering. At the beginning when we were mainly just learning about refraction and what not it was definitely hard for me to focus. But I did the work and got it done in a timely manner.
My greatest challenge was fully understanding what each thing was and how it worked. I found it difficult to pay attention to the videos we watched to learn what refraction and other things were. I overcame this by re watching the videos and rereading the content to help explain everything. Another obstacle I experienced was with my photograph I took with my pinhole camera. After I developed it, it didn't end up working and my photograph paper was just black.
My biggest takeaway is learning about refraction, reflection, waves, and light waves and being able to demonstrate that in both natural and contrived ways. I definitely learned a lot throughout this unit and I enjoyed the project. I think I grew more in my knowledge because this isn't something I have learned about it was new and different. I also learned how to design a pinhole camera and a camera obscure which I thought was a cool experience.
I think I did well on this project. I believe I put in the time and effort to create my final products even though my photograph from my pinhole camera didn't work, I still enjoyed having more hands on experience rather than just doing boring assignments the whole time.
