__Reflections__
//Think about how your group approached this lab as a team. What changes do you think you (not the teacher) could make to future experiments (including the writing of the report) to make the process proceed more smoothly?// This was my first time working with Niko, so I think in the beginning it was difficult to work because we weren't accustomed to each others processes and working strategies. But now that we understand each other, we are able to make improvements and are getting better each lab. Another thing that would probly help in the future with lab write ups is allowing more time on the actual typing of the lab up instead of thinking about it before hand. I think that by doing it this way in my next labs i will have more time to edit my work or ask questions with my partner. Expereiments however, I feel are going smoothly because my past lab's data has been close to perfect each time and run. || Read the sections on momentum and conservation of momentum What is a system according to physicists? How is this definition different from your definition (your original definition)? What does the concept of "closed" or "isolated" system have to do with conservation of mass? What about conservation of momentum? || Each step we used to create and test our clock were based on the Scientific Method's cycle. We came up with an hypothesis on methods we could use to gain an accurate clock, we did many experiments with independent and dependent variables, observed our findings, and collected data and converted it into a graph. It differed because we did not create a new hypothesis or establish a theory/ law based on only our results. I think setting up our design of the clock is not shown in the scientific method. || 7. A hypothesis's role in the scientific method is formed from the observations and questions the scientist has. It is also used by the scientist to base their testing on specifically that hypothesis. Theories are part of the conclusion of the scientific method that use the rest of the parts to back it up. Based on all the observations, experiments, and predictions, a scientist can form a theory that can essentially prove thier hypothesis on a certain matter correct. Predictions are used in the scientific method to observe and test the hypothesis, law, or theory. Using observations and measurements, they devolop the data that is used to form a conclusion. 8. In an observation, we only watch without altering nature to base ideas and questions from, while an expierement is mixing and changing nature to provide an outcome. 9. Since the scientific has no end, since observations and experiments data could lead to a new pattern and a new hypothesis and then repeat itself many times, it is more of a cycle with no concrete ending or beginning. || 2. I have Internet outside of school. 3. Homework assignments and working on labs look like they will be very helpful in the future. ||

 * 6. The first step of the scientific method is identifying patterns and observation. By examining a certain matter in science, we our able to present questions and form an educated guess, known as a hypothesis, about your topic. The hypothesis is then tested with predictions and experiments by observing its nature or testing chemically many times. The final step is to look back at the data collected to see what could be proven as a fact or if more hypothesizes and testing needs to be done.
 * =="The Scientific Method"; August 30, 2009== ||
 * I believe the main topic for this article was about observations in nature and their importance in the Scientific Method. It is essentially the first step for scientist to be able to identify mathematical equations, such as the measurements of the tree, a hypothesis and it's predictions, and a experiment and it's data. Observations in nature use mathematics to further our knowledge of constants such as gravity that are able to provide more evidence to create scientific facts, laws, and theories. Even today, scientists are observing and testing their surroundings to gather more evidence about past observations to determine if a statement could be proven false or on the right track. Using the scientific method, we are able to look at nature closer and be able to form patterns, hypothesizes, predictions, experiments, and data, by what we observe in our every day lives. ||
 * =="Wikispaces"; August 29,2009== ||
 * 1. Although this is my first time using wikispaces, I find this will be very helpful. I'm glad to have an online source for being able to see assignments and what is going on in the class, in case I was absent that day or leaving my planner at school. My parents also like to be informed on what I am currently working on in school, so this is nice to have as a resource.
