• collecting data to see how clean/repeatable it is

• analyzing data to see if it works as predicted

• figuring out how to account for friction and minimize air resistance

• Did data analysis work as predicted? Not initially b/c I made a physics error that I didn't realize until after school. This frustrated me all day. I almost gave up, thinking there was just too much friction/air resistance to work.

I bought 3 extra locks and 4 zipper pouches from Amazon to supplement the standard breakout kit.

• y ~ mx+b for linear graphs

• y ~ ax^b+c for non linear graphs and looking at the value of b to determine if the relationship is quadratic, inverse, inverse square, square root, etc.
