Peter Peng HCC Chemistry 9/16/13 ObScertainer Lab Report Purpose: What is the configuration or design inside the closed container, known as an
ObScertainer?
Hypothesis: If there is a steel ball moving within each ObScertainer, then their paths will be changed due to walls and partitions within the ObScertainers, because the steel ball will encounter these obstacles, changing its path to move within the ObScertainer. Conclusion: When doing this experiment, I used my senses of touch and hearing to predict what the inside of the ObScertainers looked like. There

I discovered the figure was rigid but also found a little partition across from it. For ObScertainer #8, I knew there was a definite partition. For my initial hypothesis, I suspected it consisted of a single curved line and a single straight one. For my retests, I studied it longer to find it consisted of three straight lines. In my retests of all the Obscertainers, I was able to study it longer, leading to more accurate readings. Sounds and feelings were more distinct after first predictions. After developing new methods after series of hypotheses, the insides of
Obscertainers became clearer. My hypothesis stated walls and partitions will change the path of the steel ball. This is true for 11 of the ObScertainers. Each one contained an obstacle that changed the path of the ball except for #12.
This can obviously be seen by looking at the sketches I have compiled. I have 36 in total, 3 for each ObScertainer. I formed a hypothesis for each one, then I took retests to make more accurate readings. In the end, I developed an actual model. This experiment allowed other students and I the chance to use their concentration, pay attention, and create different ways of doing the experiment. With different methods that I developed, I was able to create my own recollections of what I heard and felt. I used a variety of methods (as explained above), such as quickly rolling the ball around the edges, to be sure of no
During the bounce test, the ball may have been released from different points. Although it was supposed to be released from its bottom, human error may have compromised the precision of this measurement. To improve the design of the bounce test, the ball’s bottom point should be marked, and the ball should always be released from there. During the ramp test, the ball may also have been released from different points. Although the ball was supposed to be placed on the ramp so that it would be released from the front, human error may also have compromised the precision of this measurement. In addition, human error may have caused unintentional and unnecessary force applied to the ball. To solve these design issues, a door should be made that holds the ball at a certain position for a fixed amount of time before the experimenter released the ball. During the catapult test, the ball may have been held back for an excessive amount of time. To resolve this experimental design issue, a fixed time to hold the ball back should be
What do the red lines along the edge represent? What do the blue lines along the edge represent?
a two-dimensional object with real or implied lines that create the sense of direction and movement:
The first scene in which line and shape were used was one between Vincent and Butch. In this scene Butch had returned home to grab his watch and later found Vincent to be in his bathroom while he was in the kitchen cooking pop-tarts. Lines that were utilized in this scene were made by the appliances and furniture. The countertops and cabinets provide diagonal lines which help the audience to sense where the camera is wanting them to look. These lines also help to show a sense of depth to the room even though it is a small kitchen in a rundown apartment complex. Also, there are the lines that direct towards the hall that leads straight into the door frame used for the bathroom. These lines help to make a
Each ball is in contact with each other and a coulomb friction exists among them
In my daily life I always work things out as I hear them. Much of the information I receive every day is given in an auditory fashion. It can be a bit frustrating unless I can process it in a fashion I understand. Sometimes it is necessary for me to process the information by writing it down. If that doesn’t work I
The second activity to spark my interest was on page 239 and 240, VCR3: visualize, concentrate, relate, repeat, and review. I have always enjoyed visualizing scenes, surroundings, and details of anything I read, but it was always subconscious or for my own enjoyment rather than for memorization. That was why I found it so surprising when I discovered that by actively trying to visualize the scene, I could remember almost every detail. VCR3 could have been very helpful in my past with different tests, directions, or classes, and I know it will be something I will start to use in the future to remember books, articles, words, and instructions as I read them.
This dense foam is what limits the amount of force that is applied to the ball. So even if you swing as yard as you can, the ball will still only go about 40 yards. Its really cool and something you have to see for yourself.
Once the rotation was revealed, groups of “Ls” were then analyzed, questioned, chosen and emphasized within a new diagram. These “Ls” rotated around a central point and reformed the mostly rectangular plan into a circular diagram. At this stage the “Ls” were associated with other geometries
- It is helpful for patients who have difficulty understanding the complex instructions associated with other subjective techniques.
This worked well, however, it would have been better if we had two balls so mitigate the wait time, but we only had one so we made due.
What are the factors that affect the distance a ball goes and how precise it is?
One can interpret these lines as indicating the direction that a compass needle will point if placed at that position.
