Energy Transformation

Today whenever we used the cars and ramps we noticed that as potential energy decreases kinetic energy increases. Also, mechanical energy stays constant.

Newton's Laws of Motion

Newton's First Law of Motion: Every body will be in state of being at rest unless acted upon.

If we have a rock and it is resting on the ground, we can continue to watch that rock and it wont move, assuming that nothing happens to it. However, if force is applied to one side of the rock (known as unbalanced force) then the object at rest will no longer be at rest as long as unbalanced force is constantly being applied.
 

Newton's Second Law of Motion: Applying force to the mass going the same direction causes the acceleration.

If we throw a ball against the wall the force of the wall causes the mass, which is the ball, to accelerate. If we apply force it changes the constant velocity by changing its direction since velocity is a vector.

Newton's Third law of Motion: Every action has an equal and opposite reaction.

Stepping on the rocks causes force from body weight to leave a foot print. The weight will cause the rocks to move out of the way. The sand creates an equal and opposite force upon the foot which causes you not to sink. This is shown by how it displaces the sand around the foot, leaving a foot print.

Newton's laws can be related to our everyday life. The first law is being used by force upon different objects throughout the day, such as opening doors. The second law is used when putting force to the pedal to cause the acceleration of the mass of the car to move. The third law is used when we walk on anything other than hard surfaces.

Other groups results may be different because the other group used tennis balls. There is a weight difference and air resistance differences. There also could of been a difference in the way the balls were dropped and the exact time that the timers were started and stopped. Times could have varied.

Creativity Assignment

To me, creativity is having to deal with arts and crafts. It is being artistic and adding a spark to something to make it look better or make it more interesting. It can also be very fun, even if it is not a persons greatest talent. Being creative is thinking outside of the box. Creativity is important because it allows a person to use a side of their brain that stopped being used at a fairly young age. It is important because it can build talent and sometimes even relieve stress. Last semester I took and art education class and that class really brought the creative side in me, out. I enjoyed it and got to use several materials that I had never even seen before. Being creative is good for everyone, especially in elementary because it is a good way for them to express themselves. Imagination is strong during this time too. I think being creative is good and it should be used in schools. I think in order for creativity to be brought out it needs to be taught in schools starting as a young age. Creativity does not have to be strictly arts and crafts, it can have a lesson to go with it. For example, when studying planets, a mural with planets can be made in the correct order of the planets. It definitely can be combined with the core subjects. In my opinion, it is a better way of learning because it will make it more fun and interesting for students. I know a few really creative people and it seems to me that they are more laid back, happy, and just have a really positive outlook on life in general. Ultimately, I think creativity is a great thing.

Our percent error was 25 percent off. We went over our data as well as calculations and nothing seemed to be way off. The second time we did the 30 degree angle, we got around the same of our original numbers. Even though our percentage was 25% off our graph and everything was still considered correct.

Sand Bags & Motion Man

The motion man increased speed whenever the acceleration was changed, as well as the velocity.

Process of Science Assignement

You can discuss and provide examples of social, historical, and cultural influences on science and visa versa. This has not yet been addressed. You can create analogies between science process and every day experiences and find connections across disciplines.You can deal with the frustration of creating/executing a research project and develop a positive attitude required to complete inquiry projects. I am able to relate science processes with my everyday experiences. For example, using the Activity Model for Inquiry, I found that there were connections made between the two. To mention a few, on a day to day basis I make observations about things or people, I define problems whether it be for homework or personal life situations, throughout the day I either ask or answer questions, or both. I am able to deal with the frustration of projects. During the candle experiment, I wanted to be able to do everything a certain way so that the results came out as accurate as possible. It was frustrating because I wanted to make sure that it was done right and I wanted to do it several times so that I could get the best data. However, it was hard because there was a limited amount of time and supplies, my group and I were able to make it work as best as we could with positive attitudes! You can examine/analyze the inquiry process using Harwood’s Activity Model for Inquiry and/or the Understanding Science flow chart. During the candle project I felt that the Activity Model for Inquiry was easy to examine and follow during the process of it. I was able to get to each one and understand how each one links. Each one, if not all of them were covered twice. You can identify dependent and independent variables and develop experiments that require controlling variables.  I can identify dependent and independent variables. Dependent variables depend on the independent variables. For example, when we coated the wick with different substances we left one just how it was, the one that was not coated was the controlling variable for our specific experiment. Be able to clearly communicate to others. During the experiment I was able to communicate with my group well. We all got along and were able to suggest different things and state our opinions. There was no arguing and everyone seemed satisfied. Not to mention we had a few laughs and made it fun! Interpret and manipulate data in a variety of formats, such as technical drawings, graphs, tables, charts and, maps to analyze results and derive and defend conclusions using evidence Between the last two projects that were done each of these have been done. A graph was made with the data that was collected during the candle experiment. A table, graph, and maps are being made with the data from the balloon project. You can generate testable questions and design experimental procedures that are reliable, reproducible, and executable. At the beginning of the candle experiment we had to come up with several questions about candles and candle burning. From those questions we had to choose one in particular to use to test and do an experiment on. You can collect accurate data on the natural world including observations using your senses and numeric data of length, mass and time. This has not been addressed yet. You understand the definition of science, theory, law, hypothesis, and experiment (you can find definition of these on the Understanding Science website) and how they relate to each other. I completely understand the definition of science, theory, law, hypothesis, and experiment. Science was done, a hypothesis was made, and an experiment was done. You know that science involves developing an understanding of the world through posing and answering questions. The candle experiment answered a question that we had formed. The question was, does coating the wick of a candle make a difference in the way a candle burns? An experiment was done to test that question. Know that scientific ideas are subject to change yet durable and that science cannot provide answers to all questions. I am aware that science does change, all the time. There is not always going to be an answer to a question, and not everything can be proven. My group and I definitely had different ideas to make the experiment better or more accurate. Even after doing it the final time we felt that there could of been changes and we could have done a few things differently to make the experiment better. Most of these benchmarks, with an exception of a few were met during the candle experiment. It was a fun experiment and covered a lot!
