Hi there,

I'm not completely sure as to the process to improve your son's grade, but I can suggest a couple things to potentially improve the clarity of your son's data. First, what specifically did your son change between the 2nd, 3rd, and 4th tests? This may clarify the in between the 1st test of not working and the 5th test of going 5 inches. Secondly, you could recommend to your son to diagram or take better photos of the linkages themselves. From the front view, I can't exactly tell what the linkage looks like. But, if you provided more side view photos/diagrams, I'm sure that would improve the clarity of your son's work. Hope this helps, and great work so far.
