 * Lab 1: Voltage Graphs of Iron-Wired Nail and Magnet
 * Lab 2: Blood Cell Analysis using Microscopes

Lab 1, (Five Items):

In trial one, we controlled the voltage by twirling the nail as fast as possible while keeping it in the magnet's force field. As you can see, there are different range in the graph, the largest of which show times where the nail was moving the fastest. Though I'm not sure why the voltage between the iron-wired nail and magnet changed, it could possibly be due to the imbalance created by the speed of nail's spin.

Like trial one, trial two's data also shows the most voltage activity when the nail was being hit by the magnet with more speed. The red bars shown in the graph with the least amount of change were probably instances when we merely tapped the nail or the magnet stayed hooked to the nail, like in trial three. Trial two also shows that the voltage between the nail and magnet could be created by an imbalance with speed.

Trial three does not show any change in voltage (notice the pattern in the graph.) This shows that without any fast movement, practically no voltage is created. It, therefore, underlines my theory of magnetic imbalance with speed used to create voltage.

Trial four was more productive than trial three. As the nail and magnet are always touching in this trial, it was harder to use more speed in creating voltage but there are still a few seconds showing big changes in voltage. This could possibly support my theory though the voltage could easily be created by some other variables.

Trial five is much like trial three since it has the same results. Practically no voltage is created which might be due to the fact that the magnet was too far away from the iron-wired nail. In trial one, the magnet and nail were never touching but we were still able to create much more voltage. However, unlike trial one, the nail was not moving in trial five, which could perhaps be an important variable.

Lab 2, (Two items)

This image shows a microscopiv view of my blood cells. By taking a photo through the lens of the microscope, the image came out somewhat blury but the lighter circular orbs you see in item two are my blood cells. Though you can't see it in the image, I could tell that the cells were flat and had a small dent in their centers.

Item Two:

For this lab, I chose to study my own blood. I had always been interesting the blood cells' form and wondered if I would be able to see it through a microscope. I didn't know if the microscope would have enough power to see the cells well or if I had enough knowledge to use a microscope. Before, I had never really mastered using a microscope and focusing on whatever there was on the slide. But the lab turned out to be a success in two ways. I was first able to see the cells and the small dents they had which had always fascinated me. It would have been better if I could have seen them more closely but I was still suprised that the microscope worked out. I also noticed that I didn't have as much trouble working with the microscopes. I learned that using very little water on a slide could keep the organism which was being tested moist and that that could help the view under the microscope. I also learned that putting something on a slide could be quite difficult; the microscope would not be able to see through thick or thin. I'd also been taught to use cover slips whenever putting something under a microscope but from this lab, I realized it was maybe preferable but not necessary. (I did use a cover slip but a classmate close to me did not and her results were very similar to my own.) When using the microscope, I was suprisingly able to focus on the organism on my slide. This part had alway proven more difficult to me and I noticed that I had improved from past lessons on microscopes. In this lab, I successfully focused on my slide even when switching from one magnification level to another. By doing this, I learned about using the different lighting to improve your view through the microscope, something I had never learned about or done before. Overall, I thought this lab was very useful and from it, I was able to improve greatly in the use of a microscope.
