When I taught 3rd grade, one of the highlights of our year was participating in the annual school-wide science fair. Each year I tried to find a new interesting topic as the focus of our display. We would learn about and experiment with our new topic for about a month and then end our study with the creation of our science fair display. I found this particular topic while viewing the 4-H displays at the State Fair one year.
