__Reflections__

 * ==Reflection on Topic; Date Published== ||
 * I don't have all that much experiance using pages like this, because outside of school I don't usually need to. I do use Wikipedia to look things up, but that's about it. I do have internet access outside of school, and a lot of it. I do use it often, but more for my own entertainment. I think that a valuable aspect of using this site would be that we could use it to communicate to eachother if we had a question on an assignment, or something along those lines. ||

There is a difference between observations and experiments. Observations are when you loo at something in nature without manipulating it, and experiments are when manipulation is used to get a result, and to observe that outcome. The main things in the scientific method that are used are facts, hypotheses, laws, theories, and predictions. Facts are observations that can be made, where a hypothesis is an educated guess based on what is observed. A law is a predictable pattern based on past observation, and a theory is an explanation based on tests and observations. Finally, a prediction is a guess as to what might happen under given circumstances. When tests are preformed, they may neither approve nor disapprove an idea, but they can help show when the idea is valid. Not every scientist follows the same type of method, yet it is usually the same general idea. It all depends on the task at hand. || I agree more with this second author, because there is more than one way to do almost everything, it all depends on the person doing it, and how they'd like to accomplish what they are doing. ||
 * ==Reflection on Topic; Scientific Method Reading== || == == ||
 * The reading that we had was about the scientific method and how it can be used, You could have a question, but depending on the ways you go about answering it, you could get different results. The example used in the reading was how people tried to determine how many teeth a horse has. One person quoted one scientist, and another person quoted another, when someone stood up in the back and said they could just go out side and count the teeth of the horse standing there. This would be an observation, where experiments could also be used by taking the size of the horse's mouth, how big its teeth are, etc.
 * || ==Reflection on Topic; Scientific Method #2== ||
 * In this second article, the person writing seems to believe that the scientif method isn't the main thing used in research, and that all scientists do have the same idea (the fact that they all want to come up with the right answer to their task at hand) but they do not necessarily follow a type of list to get their answers. The author says that when scientists check the work of one another, they don't check whether or not the scientific method was followed, but that they did, in fact, get a valuable answer.


 * || ==Reflection on Topic; Simple Harmonic Motion Lab== ||  ||   ||
 * The process of desiging the clock was like the scientific method because we had to follow certain steps. We designed an experiment, and collected data, which led us to ideas and facts as to what happens under what circumstances. It was a little different, because we didn't get to the point of a law or theory, we just designed and tested an experiment. I think that when we changed the spring, that didn't fit in with the process. Once we got the first spring and mass accurate, we did the same with another one. Although we used the same procedure, it was a different experiment with different variables.

 * || ==Reflection on Topic; Systems== ||
 * A system is a chosen set of objects that may work together. This definition was the same as the one I came up with in class, it is just worded differently. An isolated system is a system where the only forces are the ones between objects in the system. This has to do with conservation of mass in the way that nothing is being lost or created. All mass and energy that starts out in the system stays there, changing nothing but forms or positions. This is the difference between closed and open systems, because in open systems, mass can leave and enter, therefore going against the law of conservation of mass. Isolated, or closed systems also conserve momentum. This happens because no outside forces are added, such as friction or gravity. ||


 * || ==Reflection on Topic; Energy and Work== ||
 * Kinetic energy, potential energy, and work are related because they are all energies that are in everything. Kinetic energy and potential energy are related to movement, and work is the outcome of the two energies being combined.Kinetic and potential energies can also be used to //find// the amount of work in a system, and to find out if energy was conserved or not.

Reflection on Topic; Roller Coaster Lab== || || In this lab we looked at a model roller coaster and found the energies being gained and given off at different parts of the track. This lab was definitely one of the harder ones, but in the end we were able to find the kinetic, potential, and mechanical energies, as well as the work. We used the logger pro dot method, instead of measuring the actual model. I feel like this was less accurate, but it still worked out okay. ||

Reflection on Topic; Kinetic Energy, Heat, Temperature
In the reading, it said that temperature is a standard quantity used to tell how hot or cold something is. Different scales are used to measure temperature, suck as celcius, farenheit, and kelvin. Heat is the energy that is transferred from one object to another because of temperature difference, and it s also a frm of kinetic energy. Temperature and kinetic energy are related because of the motion of molecules. Temperature and heat are related ebcause temperature is how you tell how much heat there is. And heat and kinetic energy are related because heat is a form of kinetic energy that can be produced.

Reflection on Topic; Energy Laws and Labs
The two laws of energy are that it is conserved, and that energy always foes from more usefull to less useful forms. This relates you our labs because in each oone, energy was either changing or being transferred from one thing to another. The roller coaster lab is an example of changing energy, because on different parts of the track, the cart had different kinds of energy, ewhile other forms were being produced, such as heat. In the collosion lab, energy was being transferred from one cart to another when the collisions happened.


 * ==Reflection on Topic; Scientific Imagination== ||
 * From this article, i got that science, especially waves, has a lot to do with imagination. It brought up the example of invisible angels. In order to make them visible, you alter their properties. But, it isn't as easy to do that with science. Math is the most commonly used way of solving problems. There are so many fields, such as electromagnetic, and they involve waves. It iss possible to see these waves sometimes, and they appear as a rainbow. There are tools to help see this. ||
