This week in science, we did a lot of new things. Some of those things were finding out how to get to velocity and speed and how to put them into a motion diagram. We also had a partner quiz at the end of the week. During the week we also had a lot of word problems requiring us to figure out the speed, velocity, and change in time. We also found out what the velocity would be for a rolling marble on a slanted surface. We also learned how to find the change in position over the change of time in several graphs.

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.
