This week in science we did alot of cool tests and experiments and things like that. The first thing that we did was we wanted to see how fast a normal speed of someone walking would be. In order to find out how fast someone walks we neede to make a hypothesis and a prediction and creat a test then run the test and then we would record the results in our notebooks. Which we did. Then we did another expirement. That one was to see when and where to cars going head on would crash. To do this we needed to do the same thing we did for the other test. We needed to creat a prediction, hypothesis and a test. We didn't reall have enough time to acually do the test but we made a graph that shows when and where the to cars will crash. We also made a dot diagram to show the speed that they were going at. One of the cars was going faster then the other one. These are very important things to know about. like how to make graphs and diagrams go when we get to collage or get a job and need to know these things we will already know how.

OUR 3 DAY WEEK

We did not do alot this week because of we only ad 3 days but in that short period of time we did a few things. Some of the things that we did was learned what a Function is and how it works. We also learned how to figure out how to solve functions too. We also took a quiz (with a partner) and on that quiz we had to graph things and draw dot diagrams and things like that. We went over homwork and Mr. Segan made a fun activity for us. He put pics of graphs on the board and said which way is positive and whick way is negative and he had to figure out wat dance move it was that Micheal Jackson did. Well thats pretty much all we did in the past 3 days.

What we did in cience over the past week.

Over thepast week i was absent on monday but i was there for he rest of the week. During that time we made many diffrent types of graphs and many diffrent kinds of diagrams. One of the diagrams that we learned how to make is called a dot diagram. It has many diffrent kinds of dots. The dots stand for a speed of something. If the dots are close together then that means that the speed is slow but if the dots are far away then that means that the speed is fast, but if the ots are the normal not to far apart and not to close together then that means that the speed is staying the same. Example: ( . . . . . .) or ( . . . . . . .) or ( ...............)
We also learned how to create diffrent types of graphs and how they work. During the week we also did many hand outs for homework. They were all about how you make graphs and diffrent kinds of charts and things like that. For the graphs we learned how to make them curve and put the time and position on it too.

This week we did so many new and cool things. One of those things was that we all learned all about motion. When mr. s was walkinig with the ball in his hand, he doesnt think that the ball is moved because it never went out of his sight but when he was moving meaning so was the ball. Motion is Relative- something is being compared to something else. We also learned about what is better to know nort south east and west or left and right. The answer can be both beacuse it depends wht you are doing. If you are on a hike and need directions you should use North South East and West. But if you are drinving in a car and you are ost then you should know right and dleft is better to know. This week we also cut cow eyes open. It was gross at first but then after the gross part was over it was kind of cool. We saw the lense and the cornia and more things. We also did an experiment with a car and out hypothesize was that we think that the car will stay at the same speed. Our test was when we did our test it worked and we were right.

This week we did many things. One of those things would be learning what a "Normal line" is. A "Normal line" is a perpendicular to when the line of light meets. We also made our own rubrics on Ray diagrams and Wave diagrams. Then we had four pictures on the smart board and we had to tell what's wrong with each of then if anything was wrong. Then we learned about the angles. Which would be called : Angle os Refraction and Angle of Incedence. And after that we labled it on our drawing. We learned that when light hits a surface it sometimes reflects and sometimes refracts. It depends on the surface. We also learned about the human eye and how it works. There is the pupil and the lens and the cornia. We also learned about the Behavior of light and how light travels and what an element is and things about Nature of light. We also did this carnaval which was 6 ares and each one had a piece of paper that had something we had to solve. We got to work with our tables so it was kind of fun. And we also learned about how what would happen to a light if it hits air then glass, water, and then more air.

This week in science we put a green plastic ruler in a clear glass of water and wrote what we saw. What i wrote down was that when the ruler is ini the clear glass cup that is filled with water, the ruler gets larger in size. also when you put the ruler in the cup the water gets higher in the cup because it takes up a lot of room. Also since the glass cup is wide it makes the ruler look wide and longer then it really is. One of the diagrams is the light goes in all diffrent directions. This is because the glass didn't light up. Also when you put a ruler in a bucket which is clear the part that is in the water, its being destprted because the light but when the water hits the ruler the image is changed. That means its larger and wider.

This week we also learned about particles and waves. one thing they have inn common is that they both reflect things.

Well when you take a cup of water and point a laser at it some of the light will bounce off and some will just go through. We also learned about how light doesn't have any mass so it can't go all the way to the bottom of a cup. We learned about the wave model of light and the particle model of light.

9/28/09 to 10/2/09

This week we split up into groups and out hypothsis was diffrent refletctivity on diffrent objects. we did the tests on a wall, paper, cloth, metal, wood, water, glass, and a mirror. Our prediction was that we thought that it will reflect off transparent objects and not opaque objects. our results were

wall: 5 for brightness 5 for size 0 for reflected it was small when close and big when far

paper: 5 for brightness 3 for size 0 for reflected

cloth: 5 for brightness 3 for size 0 for reflected

wood: 5 for brightness 4 for size 2 and a half for reflected

glass: 4 for brightness 2 for size 5 for reflected

water: 5 for brightness and 3 for size and 0 for reflected

mirror: 5 for brightness 4 for size and 5 for reflected

metal: 4 for brightness and 5 for size and 5 for reflected

We also learned about angle of incidence and angle of reflection.

we learned what an analogy was and how to use them with science.
