Additional information that is optional to include is an explanation of how the student came up with the idea, or how the science connects to a real world application.
I am attaching another board example, along with a zoom in of the background information. This was a third grade project that won first place in the FCE Science Fair, and went on to win first at the Austin Area Regional Science Fest. There are very minor issues with grammar, but the writing is authentic and useful to the project.
I hope this helps! Please don't hesitate to email me with questions and concerns. Everyone has been really patient with my response time, which has improved throughout the week. Thank you all for your support with these projects. The kiddos are completing great work!
