    So, most of us in Physics C have reached a point where we start to think about college and how this class is going to help us in the future. From what I have heard, most of us in this class plan on going into something that relates to physics in some way whether it be engineering or just a normal physics major. In the classroom, there is a poster that has the 10-Best Paying Majors on it which sparked my idea for this post. 

    In other math and science classrooms you can see posters like this one that try to keep people involved in these classes. STEM classes have components that are in the top paying jobs overall. More recent information says that the order of top paying jobs include a lot of engineering which includes a lot of physics.
    10. Geological and geophysical engineering
    9. Computer engineering
    8. Mechanical engineering
    7. Aerospace engineering
    6. Electrical engineering
    5. Chemical engineering
    4. Mining and mineral engineering
    3. Metallurgical engineering
    2. Pharmaceutical sciences and administration
    1. Petroleum engineering
    As I think about how hard this class has become, I realize that it will somehow help me in the future even if it just for the challenge of it.
    Until next time,

    Effective Studying

    By crazycrochet20,

    Video 1:
    a)       1. Learning is fast             2. Knowledge is composed of isolated facts          3. Being good at a subject is a matter of inborn talent      4. I am good at multi-tasking
          For me, I feel like all of these beliefs have an impact on me because I definitely have believed in all of them at some point in time. The final one about multi-tasking makes me think the most because I do check my phone while studying and try to get other things done all while attempting to learn. The third one also hits me as something I have believed in for so long because I know that I think about how some people are naturally good at certain subjects, like physics, and I do sometimes get discouraged because I think that I cannot possibly do as well as they do when really, I can do that well if I spend the time and put the effort into it.
    c)       In the video, “metacognition” refers to the awareness that students have when it comes to their level of understanding for different topics. Poor study skills leads to poor metacognition and an overconfidence which then leads to lower grades than they would expect.
    Video 2:
    a)       The most important factor in successful learning is what you think about while studying.
          “Deep processing” means going further into information instead of just focusing on what is on the surface. Going further and relating information to personal ideas can help in remembering that information whether with intention or without.
    c)       1. Minimizing distractions to maximize focus will help me to improve my learning because I will be able to take in and start to understand information better without distractions such as my phone in the way.                 2. Developing accurate metacognition will improve my learning skills because I will have a sense of what I know and what I do not understand to help me realize and focus on the information necessary to spend more time on for better grades and learning in the end.       3. Deep and appropriate processing of critical concepts leads me to try and relate information that I need to know to me while going deeper into the learning instead of just what is on the surface.          4. Practicing retrieval and application will improve my learning because I will learn how to really learn and understand information through practicing good learning strategies.
    Video 3:
    a)       1. Elaboration will help me to actively learn because it puts an emphasis onto relating topics to each other which forces me to really think about what I am learning.              2. Distinctiveness will help me with knowing the difference between topics that are closely related or even completely different.         3. Using a personal learning skill helps in remembering a concept because it is something that can be thought of right away say with the concept of throwing a ball up in a moving car to experience and see where it will land. Labs help to create personal experiences because you can see what is there and remember since you experienced it. 4. Using appropriate retrieval and application skills will force me to realize what concepts I understand by being able to quiz myself in how well I know and can explain certain ideas.        5. Automaticity will help me with the basic ideas because hopefully I will find and solve equations enough that when I need to know them, they have been completed so many times that they become easy.      6. Overlearning will help when for key points that I know I should expect on tests so I can automatically remember information because of the depth in the learning.
    Video 4:
    a)       1.    What is deep processing?
     2.       Will question generation help to increase the understanding of complex materials?
     3.       How does a student know whether a teacher will be testing on facts or concepts?
     4.       What are good question generation skills?
     5.       What are the differences between good note taking skills and bad not taking habits?
     6.       Have these questions helped you to understand certain skills better?
        The tips on taking notes applies to video lessons because you should not write down every piece of information that is given in the video, only they key and important concepts. Some examples are good in note taking as well because when looking back you can see exactly what the concept means in detail.
    c)       Forming a study group with rules for effective group study sessions
    Video 5:
    a)       You should avoid going into denial and panicking when an exam goes poorly.
          You should examine how you prepared, review the exam, talk with your teacher, examine study strategies and, develop a plan.
    c)       1. Commit time and effort
    2. Minimize distractions
    3. Attend class
    4. Set realistic goals
    5. Don’t begin to slide
    6. Don’t give away points

    Bowling...

    By crazycrochet20,

    Most people think of bowling and think about how much fun they have with their friends and family. For me, I think of bowling for a team with a focus on hitting every pin down for a clean game. Clean games equal good scores and good scores equal a happy Rachel. (Clean games are games with all strikes and spares) For the past 6 years now, I have bowled for the school and on weekends, I participated in a league to improve. Every season has its ups and downs and currently, I am in a hole that I cannot seem to get myself out of. Consistency is a huge key in bowling and if you do not hit your target on the lanes consistently, everything can go downhill. The game of bowling is also about choices. "Do I use this ball and stand at the center dot and hit the second arrow or do I throw this ball and stand 4 boards to the left of the center dot and hit two boards to the left of the second arrow?" A lot of factors impact your bowling but, one thing will always remain the same: physics. Every lane, no matter which oil pattern, has Newton's Laws all over it. The force that is equal to the mass times the acceleration shown through a grown man throwing a ball that can knock down the pins with a stronger force compared to a six pound ball that is thrown by a little girl.

    When the darn 10-pin in the corner does not fall down (the worst pin on the planet), the second law is acting on it because there is no outside force meaning that it will stay at rest. Finally, the third law is shown when you life the ball from the return, you are putting a force on the ball and the ball is putting a force on you. Same with the approach that you walk on, you put a force on the ground and the ground puts a force on you.
    Well that is all for now...
    Until next time,

    Levitation?

    By crazycrochet20,

    After my thoughts of flying in the last blog post, I got thinking about the idea of levitation. I started looking into this idea and it actually came up that there is currently a group at the University of Bristol in England that is trying to use sound to levitate objects off of the ground. This idea was first brought up by a Russian physicist, Andrei Geim, who counteracted the gravity on Earth to float a small frog. Physicists are now working to increase the size of what they can levitate to humans and then maybe even cars! They have determined that if they are to place an object at a certain point within a sound wave, the force of gravity and the force of the sound wave will cancel each other out and leave the object floating. The "mini tornado" sound waves work in such a way that it counteracts the gravity it normally feels. Although this has only been tested on very small objects so far, hopefully it will progress to larger items and even humans soon.
    This is probably the best thing that I have seen all day and maybe we will see more progress with this and find people levitating in the near future! 
    Until next time,

    Creating a Top

    By crazycrochet20,

    Wow! It is already December and we are working on rotation in class! Last year, this unit was one of the worst for me because I truly did not understand any of the concepts. I have started to figure out some of the equations and concepts but, I am going to have to work hard all this week in order to really understand the unit.
    In class last week, Mr. Fullerton gave us a challenge to solve. He gave us a pencil, two small paper plates and six pennies. Our task was to make a top that would spin for a longer period of time from those materials. For the blog post this week, we have to explain how this activity relates to the engineering design process. If I am being honest, I had no idea what it was and typed it right into the handy dandy Google. I found a website (sciencebuddies.org) which gave me the steps to the engineering process. 
    Those steps are:
    Define the Problem Do Background Research Specify Requirements Brainstorm Solutions Choose the Best Solution Do Development Work Build a Prototype Test and Redesign I definitely think that all of these were used in the activity with some of them slightly combined and happening all at once. Our problem was creating the top that would stay spinning for more than just a few seconds. Our research came from the information that we could see coming from the actual top and our background knowledge from the physics we had been learning. The requirements came in the form of the items we could use to make the spinning top which were the pencil, paper plates and pennies. The next few steps were combined because of time and we began to use trial and error to try and build the top. Brandon and I immediately knew that the the plates would have to have the pencil going through the center. We tested out where the plates would have to go on the pencil and eventually found that it had to be placed towards the bottom of the pencil. On the plates we tested the different distances of where to put the pennies and ended up putting the pennies at about an even distance towards the outside of the plates. Our final aspect that we fixed to make the top spin longer was put a small piece of tape at the tip of the pencil to keep it from spinning around all over the table. After that, we had created a top that spun for a decent amount of time with the many aspects we changed and tested.
    The next question we have to answer is relating this activity to moment of inertia and angular momentum. For the moment of inertia, the mass and radius are the factors that change moment of inertia. Since we could not really change the mass of the object, spreading out the pennies to create a larger radius impacted the moment of inertia for our top. For the angular momentum of the top, the moment of inertia and angular velocity impacted the top and allowed it to spin for a longer period of time. These two concepts combined created the top with lots of trial and error for the perfect one.
    Until next time,
