Scienc Fairs By Hilda

I teach at an inner city K-4 school. Our Science fairs consist of class projects. Then we have a Family Night we display our work.
Somehow, you need to expose children to this style of thinking and research. You don't want to stress yourself, parents or child out. Making it part of your lesson(s) would be good. Instead of a Science Fair include all academics. Children can research many different things.
Good luck in your decision-making.
