What science ideas did you learn?

We learned how to find slope

How to use variables to represent time and position, or how fast something or someone is going.



How did you learn these ideas?


You find slope by dividing the vertical difference by the horizontal difference. Here is an example of what slope may look like.

10_______ position over time
5

Slope is defined as the change in the y-coordinates divided by the change in the x-coordinates. People often remember this definition as "rise/run."

For example, a man started at 8:30, or time 1(t1), and ended at 12:00, or time 2(t2). When he ended at 12:00, he was at position 2(x2), or 4.2km. At position 1(x1), the position was 0. The man was traveling at 4.2km/30m( 2.5 kilometers per minute). You could also say he was traveling at 8.4km/1hr(5 kilometers per hour), by doubling the top and bottom.

How can this apply to modrn day life?

This is one way it can apply to real life. Slope affects some people as a snowboarder because the signs on the ramps. The difficulty of the ramp is probably scientifically found by using slope.
