What science ideas did you learn?

This week we did a lot with graphs. We learned about how to graph things with position and time. We also learned what a graph what look like in different scenarios. For example if a car speeds up the graph curves up, if the car slows down the line on the graph becomes more horizontal. Then we realized the faster the object moves the more steep the line is on the graph. If the objects moves slower the line is more horizontal. Then we learned if the line is exactly horizontal then that means the object isn't moving.

How did you learn these ideas?

We learned these ideas by Mr. Segen made a little car move and told us to graph it's movement. We all graphed the movement and then we compared as a class which was the best. For example some drew a line that all of a sudden just became more horizontal. Mr. Segen then asked that person questions like does the car just slow down or does it gradually slow down. Then that person adjusted their graph so it had a curve which shows it gradually slows down.

Why is it important to know this idea (What real world application is there)?

It is important to know this idea because when I'm older I could be a scientist and I will have to graph the speed of a car that starts a one point and ends at another point. I will have to graph how the car drove from the beginning to the end. Finally I will have to think back to 8th grade science and show how the car first curves up, drives a little bit, and then how the line curves back to more of a horizontal line.
