This week we did alot of reviewing for the upcoming test, but we also learned some new science ideas. We learned about friction and air resistance and how it affects scientific learning. We continued on our force diagrams and made more number sentences. We also learned about Newton's third law and to draw a force diagram for it you need two seperate ones to show each vantage points. These new science ideas will help me on the test.
I learned these ideas by taking notes and doing homework. I also completed a 5 page extra credit study guide that helped me. Not to mention that i completed many review questions for the test. We also had many examples and demonstrations. This week we even wrote a small story about friction to help our knowledge. Without these ways I wouldn't fully understand the science ideas.
These ideas are important because they will help me on the test. Also it will prepare me for more scientific things in the future. It also helped me furthermore my knowledge on the the last and the present unit that we are enduring. These science ideas are important because it will help me in the future, not just the present.

The Week of December 7
This week we learned many more science ideas. We learned more things about force diagrams. We now don't just put vertical arrows we put horizontal arrows to show if the object is moving or being pushed. For this you have to make two number sentences representing both displays of motion. The most important thing we learned this week is that delta v arrows are always in the same direction as the unbalanced force. Of course one is on a force diagram and one is on a motion diagram. This was a breakthrough which helped us understand most of the work to follow it.
This week we learned information in many different ways. Like always we took notes and followed examples and experiment. But, this week we learned information in many more different ways. My favorite way was in the form of a debate. Our class chose sides on a science idea and we argued our idea until one side figured out they were wrong by our information and examples. I found this a fun way to learn.
These science ideas are important to know, because when we have tests or quizzes this following week we will need to know this or we wont get a good grade. Also later in the year, when we go on to different subjects we might have to go back to this to furthermore our learning in that specific subject. These are two good reason why this is important.

The Week of November 30th
After our science test this week, we learned many key ideas about motion. We learned why motion moves and how to draw a force diagram. We also learned that gravity is not an object and to express it we should use the word earth. So when you put a book on the table, the book pushes down and the table pushes up at the same force making the book rest on the table. If there was more negative force the book would fall down, and if there was more postive force the book would go up. We also learned how to write equations for these objects. For my previous example it would be 5n +-5n=0n, making the position equal. Of course n stands for newtons. I also had to guess the amount of newtons.
We learned this by many ways. We were taught vocally, by Mr. Segen and we wrote down good notes. Although this was key in my increase in knowledge, the most important way we learned this was through models and diagrams. We used bowling balls, small weights, and even ourselves to model motion for our learning. One day we even got to push a car, so we could represent the motion of how the car was moving in mid-push and after we stopped. This was how we learned the science ideas.
This is important to know because although we already learned alot about motion, but to fully understand motion and to become a scientist you always must keep researching further, because there is always something to learn in the world of science. Also if we learn about different science ideas and there is a problem or situation that need what we already learned we can process it easier using the fundamentals of motion. These are really important reasons why we should know this
