How to Grow Mold for a Science Fair Project
Growing mold is easy, especially if you are doing it on purpose. Mold growth is determined by three main factors: temperature, moist conditions, and the source of nutrients on an organic substance. Mold can grow on everything from fruits and vegetables to bread. Using bread as a base to grow your mold for a science project is probably the quickest and easiest since most of the tools you need are already household items.
