In physics class on Friday we had a sub and there were no papers to turn in. We were handed out two papers and they are both due on Monday if they were not finished in class. The first one was the background to the lab we will be doing on Monday, there were a few questions on the back that needed to be finished after you read the lab. The other paper was a reading guide with the packet the sub also handed out. During class we just worked on those two assignments. Overall it was a pretty relaxing class where people worked with who they wanted which to me looked like people just went back with old lab partners that they missed working with just like I worked with Carlie again.

This Monday started out as any other day in physics would, by turning in numerous amounts of homework, this including the Bling Project and Light Wave questions. After turning these in, Mr. Ebersole broke up our class into groups based on who was at school on Friday. He then explained that we needed to finish our labs from Friday and begin the camera dissection lab. Mr. Ebersole repeatedly reminded us all to make sure that the batteries were out of the camera in order to ensure our safety.  After our instructions each group worked on completing the labs assigned for the remainder of class. At the end of class Mr. Ebsersole told us that our only “homework” was to work on the test review and that tomorrow is our time to finish the labs and review for the test on Wednesday. This concluded our class. Even though this Monday was pretty ordinary one special thing happened in second period, we had a special guest. This guest happened to be one of Mr. Ebersole’s professors who were evaluating his performance so he could learn what he’s doing well as a teacher and where there is room for improvement. Though none of us really talked to this special guest, I noticed him admiring my Miami hoodie.

QOD: How can you measure the focal length of your disposable camera?

Though I am not certain, I believe that this is the answer. You would remove the lens, focus it on an image, and move it back & forth until the image becomes clear. Once the image is clear you can take a ruler to measure the distance.
