**__//REFLECTIONS://__**
__Accelerated Motion Lab; 10/28/09__ The Accelerated Motion Lab was about measuring objects increase speed over time. Acceleration was measured by a ticker-timer, that ticked 60 times per second. We measured different objects with different masses and different heights, measuring different accelerations for each one. When our data was collected each of us measured how far each dot was from the previous dot for one of the objects. This measuried the total distance as well as the acceleration. We learned that the acceleration is always the same for falling objects. Objects on a surface are subject to friction which effects their acceleration depending on different variables.

__Applying Energy Laws to labs; 10/11/09__ The rules of energy in thermodynamics and the rules of conservation of energy are very similar. Energy can not be created or destroyed, but it can change form. When it changes form, it becomes less condense and less useful. These rules apply to the Collision of Carts, Mechanical Equivalent of Heat, Energy on a Ramp, Roller Coaster, and Calorimetry Labs. In each lab energy was conserved. In the Collision Lab Potential Energy was converted into Kinetic Energy, as well as some heat on impact. This also happens in the Roller Coaster Lab and the Energy on a Ramp Lab. These Labs all consist of a point where an object is not moving, but then moves due to a transition of energy. In the Mechanical Equivalent of Heat and the Calorimetry Labs there was useful energy converted into less useful forms.

__Law of Conservation of Energy; 9/27/09__ The law of conservation of energy states that energy isn't destroyed, it can only change form. Some fo these forms of energy are PE, KE, and Work. Potential energy is stored energy without motion. Kinetic energy is energy in motion. Work is an applied for over a distance. These forms of Energy are all measured in Joules. Since energy can not be destroyed, it changed from one form to another to conserve an equal amount. PE, KE have the most obvious relation because it it visual. When there is a cart at the top of a roller coaster it holds X amount of PE, as the cart decends to the bottom of the track the PE turns into X amount of KE. This relation conserves energy.

**Independent Clock Lab Reflection; September 14, 2009**

 * **How was the process of designing and testing a clock similar to the scientific method as discussed in class?**
 * The past two weeks we have been studying the basics of the scientific method. The clock lab is an example of how the scientific method is used. The process of designing and testing our clock was similar to the scientific method because we did use the method to complete our experiment. We used preconceptions, experiments, observation, data, and patterns routinely in our lab.**
 * **How did it differ?**
 * In this lab there was just the basic outline of the scientific method. There were no laws or theories created. The clock experiment didn’t require a guideline of steps. We just experimented and observed data.**
 * **What "steps" in the scientific process were present and which were missing?**
 * We started with a preconception that we could make a certain amount of weight bob on a spring a certain number of times for an accurate measurement of time. We then experimented and observed our data to conclude our lab. The steps we missed were facts, theory, law and hypothesis.**
 * **Was there a part of the activity that is not a part of the scientific process?**
 * The part of the activity that is not a part of the scientific process could be guessing. But even then, when we guessed and checked, we used parts of the scientific method like observing and data.**

Reflection: Review Questions 6-9; September 1, 2009
6) The Scientific Method consists of observations, hypotheses, predictions and tests. Observations leads to hypotheses and predictions, which leads to testing. Eventually leading back to more observations--creating a cycle known as the Scientific Method. 7) A hypothesis is a tentative educated guess about how the workd works. Theories are well-substantiated explanitory descriptions of the world based on numbers of varified observations and experimental tests. Predictions are tests executed to observe if the hypothesis, law, or theory is correct. 8) Observations are of the world as it naturaly exists. An experiment controlls the situation as desired. 9) The "Scientific Cycle" would be a better title in lieu of the Scientific Method because there is no set way to solve the questions of the physical world. The "Scientific Method" implies that there is only a direct route to a final solution. The "Scientific Cycle" clarifies that there is no end to answering questions about the world, and that there is not a specific way to go about solving them.

The four guidlines to find scientific solutions are: observation, hypothesis, prediction and testing. Science Through The Day concludes these elements as the Scientific Method. Without each element there would be no answers. If there was only observation then we would only be "wrestling with shadows". A prediction and hypothesis follwed by testing, leads us to see the objects causing the shadows. || 2. I have 24/7 access to the internet outside of school. 3. Wikispaces will make it easier to study physics with the class. ||
 * ==**Reflection on The Scientific Method; August 30, 2009**== ||
 * In the Scientific Method chapter of the Science Through The Day article, it is explained that science is a continuous cycle of answering questions about the physical world. This cycle has no end and does not have an answer. Sure there are answers and solutions to questions, but these only lead to more questions that only lead to a more detailed understanding.
