Building Better Batteries

Image
     This is my action project for my class Energy, in which we had to design a battery out of just household items. The question for this experiment was if either distilled water or vinegar made a better battery. My hypothesis for this experiment was that the vinegar would make a better battery than the distilled water, as the vinegar is more acidic. For the materials, I used vinegar, a penny, a nickel, a container, and a multimeter for my battery. The materials The steps for this experiment were as follows: 1. Pour vinegar into the container 2. Put the coins into the vinegar, making sure parts of the coins are exposed 3. Put the prongs of the multimeter on the exposed part of the coins and record the results 4. Rinse out the bowl and repeat this process with the distilled water When I performed this process with both liquids, I got these results. Left: Vinegar Right: Distilled Water Since the vinegar, while still being a small amount, resulted in a higher voltage, my hy...

Making Infomercials

     This is my action project for my class Energy, in which we had to create an infomercial comparing two items. In this unit, we've been learning about kilowatts, energy, power, and functions. We also had 3 engineers from Arup Engineering come in and tell us about their jobs and learned how many kWh different objects use. Overall, it was nice, nothing was too challenging yet I still learned a lot. Although, I do wish we went on more outdoor FEs.     For this action project, we had to create an infomercial comparing two items, and advertising the better one. I choose Whirlpool and Samsung washers, with the Samsung washer being better, as it cost less while still using the same amount of energy. We had to design graphs, create functions, and find a renewable power plant to compare the amount of energy both washers used. We also had to come up with a script for the video, and either voice it ourselves or have someone else voice it for us. I chose to do it myself....

Digging Up Fuel

       This is my action project for my class Energy, in which we had to create a slideshow that talks about a fossil fuel in a country. We've discussed fossil fuels, graphing, slopes, and atoms in this unit. We've also done some experiments relating to combustion, all of which involved some chaos. We haven't on any FEs specifically for our Energy class, but I think what we've been doing in class makes up for it. It's all been very interesting, nothing too challenging and nothing too easy.     For the action project, my fossil fuel was oil and my country was China. Last year, China reported a decrease in oil consumption for the first time in decades. This was due to China being on lockdown, meaning oil wasn't needed as much. This story intrigued me, so I decided to do it. Getting all the information did take some time, but I'd say I'm happy with the results.     Going into this project, I had no idea what I was doing. I didn't know what I wanted ...
