=Conclusion:= The Green's average time per position was 8.60 seconds, Red's was 3.34 seconds, and Blue was 6.28. We concluded that Green was the slowest moving bubble, and Red was the fastest. We also saw a relation between the time and the position of the bubble on the graph and learned that the speed of the bubble which is meters/second in a certain direction and known position is the bubbles veloctity.
