Week of November 16

This week I learned many key science ideas. We learned more about motion. We applied graphs and pictures to figure out experiments including colliding cars. We also learned about displacement, or the distance from the starting and end point. Most important, we learned how to make a horizontal and vertical motion diagrams. This is just like a dot diagram but it has the directions, the origin, velocity arrows, and delta V arrows. A delta V arrow is the change in velocity. If it gets faster the delta V arrow points in the same direction as it originially was going in. If it gets slower the delta V arrow points in the opposite direction

We learned these ideas many ways. One way was Mr. Segen carefully went over it with us to make sure we grasped the concept of this. We also learned this, by experiments, notes, and pictures we drew that we based on this week's learning. Also quizes are a great way to learn and review earlier learned information. Most importantly, we learned with the help of our science squad group. They helped me grasp the concept when i didn't understand.

It is very important to know this because as a scientist you must have a basic understanding of all of the topics. Even after going to anopther topic things may relate back to this. Which is a great reason why it is important to know this. Finally, as cheesy as it sounds it is a great conversation peice. It seriously makes you look smarter and in the process of it you may inspire a person that you are talking to.

The Week of November 2nd ( short Week so not as much writing)

This week not much was done due to a short week. Although our usual work load was lessened we did learn some pretty important things including slope and speed. In what we are talking about slope and speed are the same thing. To find the slope you put the vertical change over the horizontal change from a graph and write it as an expression. Also slope is used to describe the measurement of steepness of a straight line. We did some exact examples using scenarios such as super grover's speed which equals in our minds, x(t)=200 m over s. In conclusion that is what we did this week.

The Week of November 2nd ( short

October 26th, The Week of

This week we learned about motion. We learned that motion is relative which means it can be scene differently from different vantage points. We did many experiments using telescopes,trying to dscribe the motion of different objects. We also used car scenarios where different people are looking at cars moving differently. We connected science to math saying tht motion is like a number line,some movement is negative and some is positive. This depends on what direction something moves in.
We also learned how to make dot diagrams which describes the motion or speed of an object uisng dots and distance to reperesent the amount of seconds it takes for a certain object to move a certain distance. I was also taught how to make a graph using speed and position and curving the line according to how fast or slow and object is going. The last thing we did was mark cars speed and made tables and graphs out of them. We did this with the help of a metronome.
