Dumb Blondes: Rumor or Reality

I wrote this essay for my science fair project. For my project, I had to analyze IQ levels to decide if hair color actually had an effect on intelligence levels or if it was just a rumor. In my essay I argued that being dumb because you are a blonde is strictly a deriding rumor. A strength I had in my essay was using facts to support my claim. Something I could work on for this essay is keeping my reader involved. I think I focused too much on proving my point that I kept repeating myself. This caused my essay to not capture my reader's attention as well as my other essays.
