Okay, I plan on going to county science fair after my school science fair this year. I'm in 9th grade, and did a double slit experiment (with light!.) A friend of mine (best friend) has won first place before on a county and state level (same experiment.) And several grand prizes type things. He also won several second place science fairs. He told me that my project was good, and could win first place on the county level, if I some how tie it into modern (last 20 years or so.) science. I'm stumped on this one. Should i mention the electromagnetic force being a primary part of the unification of forces (string theory?) And tie that into my future work portion(that I plan on working on string theory as an adult.) The friend of mine who won the science fair last year merely found the best growing conditions for green algae, which obviously CO2, light, etc. are the best, but he tied in future work of using green algae for oil, and ended up winning. Thanks guys!
