These are both helpful ideas. Plus he can also make nice BIG charts with that suggested poster board and markers....a mostly hand-created display might have more visual oomph than a single sheet or two printed up on a computer. He can always use huge type-fonts to print up the words or single letters for signage too.
I must say, it is hard to resist the pull of the overdoing parents in our midst, the dads that build the stunning Pinewood Derby cars, the moms that just plain write student essays, but it can be done...I do it all the time. I would like to point out, though, that the parent was not saying she had done the scientific work of growing and of studying and of gathering the information on the plants (which is supposed to be the main emphasis of this activity), she was asking how to make a chart so the work her son had done would be displayed. I'm a more hard-core truth-teller than many I know, but to say or to imply that someone asking for *display* advice for a science fair project is outright cheating...you really think so?
Yes, much of the success in life is learning how to make our work and even ourselves appealing to others, but this is a "Science Fair" not a "Visual Display" or a "Merchandising Class" Fair.
YMMV,
agnes!
