18	note: you should use Logger Pro to get your velocities, but ignore the signs and treat them like speeds; then add back the signs
19	in a way that makes sense; that is, don't trust the signs given by Logger Pro; use common sense (right is + and left is -)

22	repeat the data table twice more, for "in which 2 remain 2" and "in which 2 become 1"
23
24	remember to write a sentence or two that summarizes your findings, i.e. a conclusion statement
