I believe the objective I did the best on was Objective 2 "Can design an experiment with appropriate IV, DV, an constant variables. This was my strongest objective for two reasons. First, the quiz we took earlier in the unit and all of the labs were good review of this objective. Also, this is not new material for me (we have been working on this objective since elementary school.)
The objective I need to improve the most on would be objective 1: "can define and use all vocabulary words correctly." There are a number of words from the list that I am still unsure of how to use (including interpolation & extrapolation.) This objective would be an easy one to work on. In the future, I could look up the words in the textbook and spend some time learning how to use them
The objective sheet was helpful in knowing what was going to be on the test and what vocabulary to study. However, it would have been more helpful if it included examples (or pages in the book where examples could be found.)

One category
I feel that I particularly embody is the “balanced” category. I enjoy challenging
myself in the classroom and work hard to learn the material, get good grades,
and find things that I enjoy in school. However, I also realize that the grade I
get on my next test or even my overall GPA is not as important as my overall happiness.
I am involved in at least two sports every season, as well as working and participating
in clubs. While sports take up lots of my time, I have found that it is a good
way for me to balance my life and relieve any stress I may have. While I do
have to budget my time well and still make sure to keep school as a priority,
having lots of extracurricular activities enhances my intellectual well-being,
keeps me physically fit, and provides an outlet for better emotional
well-being.
Another
area that I feel confident in is the “communicators” category. I am defiantly a
“people person” and I often do well working in groups with my peers. The reason
I love working in groups is because you have the opportunity to learn from your
peers, bounce ideas off each other, and constantly be checking each other. In
addition, I believe that the ability to work well in a group that is extremely important
in everyday life. For example, many jobs will require you to collaborate with
coworkers on different projects, and without the proper communication skills
you will not do well in the workplace.
In addition, these communications skills also translate into my everyday
life while I am at work dealing with my boss, coworker, and customer I have to
have good communication skills; and when I play sports on a team I have to be
constantly communicating with them in order to be productive.
One area
that I feel like I could improve is the “knowledgeable” category. Often, I find
myself so caught up in whatever topics I am currently learning in my classes
that I forget to pay attention to what is going on in the world around me.
During this coming year I would like to make it my goal to learn about a wide
range of topics. I can do this by watching the news or stopping to read a few
interesting newspaper articles each week. I believe by adding more enriching
reading materials into my life, (like Bill Bryson’s A Short History of
Nearly Everything) I can become more aware of the issues around the world.
Spring lab
Spring Lab Conclusion
The amount of mass (g) added to the spring correlated linearly with the amount the spring stretched (cm.) The length of the spring increased positively as the amount of mass was increased. The slope of the equation is 0.08 (g/cm) and the y-intercept is 11.43 (cm.) The uncertainty in the x-axis was (+/-) 5g because the masses used during the expiration appeared beat-up, old, and probably not very accurate. The uncertainty in the y-axis was 0.175 cm because the biggest range in measurement between trials was 0.35 cm (this was with 200g of mass attached to the spring.
There may have been systematic error involved in this expirament due to the relative inaccuracy of the measuring tools used. In addition, there was human error involved in the measurements taken- especially at the 200g level. The inaccurate measuring tool, like the meter stick and old masses. The nature of the spring may have negatively influenced the measurements of the length that were taken, in that it was difficult to stop the spring from bouncing and take an accurate measurement.
In the future, more accurate masses could be used to lower the amount of uncertainty in the x-axis. Also, the meter stick could be mounted to the apparatus, (no opportunity for human error in not holding the meter stick straight) and more time could be given in order to allow the spring to completely stop bouncing before measuring the length of the spring.
