When I was growing up submitting a project into the Science Fair was an option, but not in this small town. From what I’ve heard it’s mandatory starting in the 4th grade, but at this point not sure how many years is is mandatory so we shall see.
This past summer our oldest son did an experiment in the 4H corn category of the fair and won Grand Champion. We were so proud! Many of his past teachers mentioned that it would be a good Science Fair Project, but at the time I assumed the Science Fair was optional so I thought it was a general statement. My attention did spark though when the Science Fair requirement papers were sent home and the realization that is was mandatory became a reality. Um I wonder if what the teachers said in passing was true that we could reuse the data and enter it in the fair?
Whoo Hoo we got a free pass this year! His 4H experiment for the fair was accepted, so all we had to do was move the data onto the required board and he was set. I must say though it’s a damn good experiment and thankfully all the time and effort he put into it last summer is paying off since he can use it twice. I’m going to have to remember that in the future!
So the experiment was planting field corn seeds at different depths to see what depth would produce the healthiest plant. He took for buckets full of dirt from the field, planted 5 seeds in each bucket at different depths (1″, 2″, 3″, and 4″), watered them regularly, documented their growth over 6 weeks, measured the height of the plant and width of the stalk, and in the end created a poster with documentation & pictures.
His experiment proved that planting field corn at 2″ in depth made for the healthiest plant, which surprisingly enough is the depth that farmers plant their corn in anyway.
