The week of the 2nd

What science ideas did you learn?
We learned about how slopes are position over time (p/t), speed is position divided by time (x(p/t)), and the function of a graph table (x(t)=(p/t)*(t).

How do you know?
We tested the formulas by filling in the numbers with the info on the graph and the formulas were right. For example p/t on a graph it could be 10/5 or 14/2 and if you divide them you get 2 for both.

Why is this important?
This is important because when were older we will have to graph info and find out more info from that info, and these formulas would help us with them.
