This probe can be adapted and administered to all grade levels prior to a unit about photosynthesis to reveal student understanding and misconceptions. Related research is included to help you understand common student misconceptions, as well as suggestions for instruction and assessment. The approach suggested will build student understanding of this complex and abstract topic.

Everyday talk has a way of messing with student's science knowledge. Stores sell "plant food" which is not food for plants, scientifically speaking. Food, in a biological sense, provides energy to the plant. Plant food provides nutrients to plants which are important, but not the same as food. Students really struggle with this.
