About sciencemom

My name is Kayla Fay, and my husband and I have four sons. We’ve turned in over 25 science projects. We remember the disappointment of having an experiment fail. We know how frustrating it is to search for a good project at the last minute. The five 24 Hour Science Projects have experiments our sons have completed successfully. The project guides will help you have the same success with your science experiment!
