Today in class we started to worked on making batteries. But before we started we went through some of the basic concepts. We learned that all elements have different attractions to elements, also known as electroneg activities. We also learned that when an atom that can lose electrons more easily than an atom of a different element that comes into contact with one another. One of the main concepts that we learned was about oxidation and reduction. It is a reaction in which there is a transfer of electrons. The difference between the two is that oxidation is the loss of electrons and reduction is the family of electrons. An example is when Cu and O come together, Copper becomes becomes oxidized and oxygen becomes reduced .
To start the battery we needed to use pennies, cardboard, and vinegar. Before we put anything together we had to make sure that one side of all the pennies was filed to where the zinc was visible. We then used cutouts for the pennies out of cardboard. We then dipped it into vinegar so that electrons would flow through from the zinc. Once completed we but the materials together. We then but the copper at the bottom, then zinc, and then cardboard for the electrolytes. We did this repeatedly so that we made use of all of our pennies. The repeated stacking increased the charge (volts) because they were arranged in series. The chemistry behind it that made the experiment work was that at contact with the electrolyte solution, each metal formed positive ions. Since zinc losses electrons more easily, they traveled through the copper ions.
Looking Inward:
Overall I feel like I got really desirable results. In the beginning we didn't get the results we wanted but after making revisions our results improved to where we wanted them to be.
Looking Outward:
I believe that I worked well with my group. We all worked together and we didn't run into problems. I believe that I contributed well and help complete the project.
Looking Back:
Everything did not work out as planned at the beginning and nothing worked. It was frustrating but we didn't give up hope. The next round we made sure we sanded the pennies down again and made cleaner cutouts. We also added more pennies so that we could get more volts for our battery. After the revisions it worked and the light was really bright.
Looking Forward:
If I could do this again something that I would do differently would be to add more pennies. The first time I added more pennies there was a significant difference and I would like to see more improvement.
Looking Beyond:
The chemistry behind it that made the experiment work was that at contact with the electrolyte solution, each metal formed positive ions. Since zinc losses electrons more easily, they traveled through the copper ions.
Take Aways:
Some take aways that got from the experiment was the importance of revisions. In the beginning of the experiment things weren't going the way as planned and it simply didn't work. After going back I made sure that the next draft everything was neat and the cut outs were more precise. Also making sure that the pennies were sanded down nicer. After the revisions it worked out better. The lesson learned after words was the importance of revisions.
