The cart on a hill lab was another one of my favorite labs to do in class. The cart on a hill lab was about a $100.00 cart that had two weights/masses that we(the groups we had at the beginning of the year) had to use in our data collecting. When we collected our data we had to run the cart down a track and our data depended on the length of track we chose. The types of graphs that we used were position vs time, velocity vs time, and acceleration vs time. The velocity vs time and the acceleration vs time graphs are a little bit different than the position vs time graph because the velocity vs time and the acceleration vs time graphs have an extended y-axis and the position vs time graph doesn’t. After we finished the lab, we started a worksheet. This worksheet was just a reveiw of the lab. Each group was given a problem to do on a whiteboard and as a class, we got through numbers 1 and 2 and we started number 3(which was the number that Rebecca Yang, Tyler Blum and I were given) but we didn’t get to finish it because the class wasn’t cooperating. This caused Mrs. Okroy to suddenly move our seats. I stayed in the same spot(s), but now I work with Zayd A., Michael T., and Davae R. After Mrs. Okroy moved our seats, I was not a happy camper. We did a little bit of work in our new groups(and didn’t want anything to do with my new group at first but now I don’t mind.). After we had our seats moved, Mrs. Okroy did some talking and I kept my back to my new group and I didn’t make eye contact with Mrs. Okroy and I changed my body language because I was very ticked off(because the seat change was so sudden and change quite suddenly isn’t exactly easy for me) and as soon as the bell rang, I was out of the classroom because I was NOT in a mood to talk it out with the teacher. After I left the classroom, I stormed up the stairs(because I was quite ticked off) and I got my stuff so I could go to my next class, I took all the stuff off my locker door and put it on the shelf and I slammed my locker door(to get rid of some of my anger) and I huffed off to my English 3 class(with Mr. Martin). The next day, we had some stuff to do in our groups and the teacher had asked the class if we needed a new worksheet and (unfortunately) I needed one. So Mrs. Okroy went and made some copies of the sheet that I needed and then we talked about the events of Monday, how change doesn’t exactly come easy to me and how she wanted to talk to me after class on Monday but she didn’t get a chance to because I was out of the classroom like a rocket. Some of the benefits of working in a new group are that you get to experience the ideas and other things that new people bring to class and you get to learn a little bit more about the people in your group. In class we are getting some iPad’s that will be at our group’s disposal in class that the different groups can use to take notes in class. Some of the negatives of using iPad’s in class would be that we couldn’t go on the internet or use the app store/iTunes store to download stuff and we can’t play games on them either because they are for note taking only. The first quarter of school is gone and we only have 9 weeks and 1 semester left in school. I feel that the first quarter went really well. My grade in class was right where I expected it to be because I usually go back and forth between a B and a C in any science class that I have. In my opinion, Mrs. Okroy is one of the best teachers that I have EVER had!!!!!!!!!!!!!! Mrs. Okroy has the best personality and the way that she teaches is easy to understand and I know that she is a teacher(that I know) that is quite easy to talk to about anything. Mrs. Okroy is one of my favorite teachers at tower and I know that she has high hopes for me in class. My participation in class was probably a little bit better because I had the most participation(in my opinion) this week. I don’t think that there is anything that I need to work on(besides controlling my tiny anger issue;)) in class. The past week was one of the(almost) best weeks that I’ve had in school/physics class!!!!!!

buggy lab, one of the most fun labs that I’ve probably done in my science class history. The buggy lab was about a little battery operated buggy and we had to work in our lab groups. The stuff that we observed in our lab groups were: the color, how fast it goes, the treads on the wheels, the flashing lights(& the solid ones to), the fact that the buggy was made in china, the battery-powered motor, the materials of the buggy, the fact that it only goes in one direction, and that the wheels move together or at the same time. There were also some things that we thought that we could measure but couldn’t because we either haven’t learned about it or it just wouldn’t work. After we came up with a purpose and made our predictions and came up with a list of materials, we broke up into our groups, we set up a procedure, we came up with our dependent and independent variables and our constants. In the buggy lab, we used position vs. time graphs. The next day, we started to collect our data. When we collected our data, we did two trials. The trials were different between the groups. After we finished the buggy lab, we did what was called a lab practum. A lab practum is basically a lab that is graded like a test or quiz. In the lab practum, each group was given two different graphs and told to go ahead and “walk it out”. My participation in the lab and the practum was good. My understanding of the data presented in class was good. I would rate my understanding with a 9.5 because I tried to help with the data collection but there were a couple of instances where I got a little distracted. I fee that I still need to work on helping to present the data that my group has because in class I just stand behind the board and I don’t say anything.

During the last 2 weeks in physics class, we started a new lab about a battery-operated car, we took a test, we did a ratio worksheet(and we talked about it), and, in an unrelated subject, there was spirit week. The test that we took was about what we learned about in the last reflection. In the lab about the battery-operated car, we started analyzing some stuff that we could use to help analyze the car. As a class, we brainstormed tons of ideas and then we cut some ideas out because we decided that they wouldn’t work in what we thought that we were going to analyze. We also learned about ratios and sig. figs.(significant figures). The same week we did the sig. figs., we also took a progress quiz about trendlines and graphs. I am still confused on the significant figures thing but I know that we are going to talk about it more later in the semester. I do not feel that I have any questions about anything that we have learned about over the past 2 weeks. We came to know about the lab by the proctor explaining everything and answering any questions that we had. My participation in class over the last 2 weeks would get a 7.5. In my understanding what we learned in class would also be a 7.5. I feel that I still need to work on my study habits and keeping my focus on my work. These past 2 weeks were strange because they were shortened by a progress quiz, a test and the NWEA test.
Over the past three weeks in class, we have learned about the class rules and school rules, we did a mystery box lab, and we have done a few graphing worksheets. In the mystery box lab, as separate groups, we examined several items from a box. Some of these items included: a pendulum, some wooden sticks, some spheres and misc. circles, some film canisters with pennies in them, and some oddly shaped floor tiles. When we had to examine the items, we had to measure their mass, take their diameters, lengths, how many times the weight swung back and forth, and a few other things. After we finished doing the lab, we broke up into our groups and we were given a whiteboard and we were given one of the stations and told to take the data and put it into a graph. My participation in the lab was very high because I knew that I would get points for my participation. Before we started the lab, we did a story problem type of activity about a girl who had a fight with her mom about her boyfriend, a fight with her boyfriend and her sister, tried to go to a coffee shop but was told that it was closed, was wandering up and down the sidewalk, went to cross the street and was hit by a drunk driver and killed. I completely understood what we learned this week and I had no problems understanding what was taught to the class. In class we came to know and understand what was taught in class by doing a lab and doing two graphing worksheets and a ratio worksheet. I do not know if I still have any questions about what we’ve learned in class. I feel that I still need to work on my focus in class/not getting distracted by other things while we are doing something.
I will post about this week tomorrow.
