Science picture of the week

by Jasmine Braman

In this weeks science picture our class was making wet-cell batteries. We lined the beaker with tinfoil, and measured out 75 mL of vinegar. We were also given two alligator clips and a volt meter. The task was to measure the amount of voltage when a strip of metal was help inside the beaker. The connection between the vinegar, tinfoil and metals, caused chemical reactions, allowing electrons to flow, creating a current, creating a battery. There was four different metals we tested with the vinegar; we tested Aluminum, Copper, Iron, and Zinc. All of theses metals were tested with the foil, and the vinegar. (One time we tested aluminum without vinegar.) There was a conductor attached to the metal strip, and the other clip was attached to the foil. While attaching the alligator clips, our group realized that the positive and negative outcomes on the foil and metals differed. We also tried to power a light bulb using the battery we had made. Our group wasn't successful. As a class we also thought about the other liquids that we would try with the metals. We came up with a lot of acidic liquids such as orange juice and lemon juice, along with other liquids that weren't acidic such as water and salt water.

Picture of the Week

by Kyle Coburn

In the picture, the balloons are stuck to the side of Cody's head. This is due to the electrical charge of the objects. Moments before the photo was taken, Eric had rubbed both of the balloons against Cody's hair. By doing that he created enough friction to displace the electrons. The electrons of Cody's hair became loose and were attracted to the balloon with the result being that his hair and the balloon each had an electrical charge . Since the balloon had an excess of electrons, it had a negative charge and since his hair had a depletion of electrons, it had a positive charge . Since each object had an opposite charge, they were attracted to each other. Also you can see that there is hair that is farther away from the balloon but it is still attracted. This is due to the electrical field that is produced by the balloon.
