Here is my display board at home. I did it on the flagellum motor which is in bacteria. At the science fair a lady said to me, "Oh, you are going to be a biologists or scienctist aren't you?" All I could nicely muster was, "Haha, no. Science just isn't my thing!!" Anyway, I was able to get a good in-depth study of it! (NOTE: somehow I managed not to get a picture of the younger kids display board so I'll have to put one up soon.)
Just some different display boards. Everyone did great!!
