The questions in this worksheet/discussion activity help students understand that a large part of a plant’s mass consists of water, most of the biomass comes from carbon dioxide, and minerals from the soil contribute only a tiny amount of the plant’s mass. The first attached file has the Student Handout and the second attached file has the Teacher Notes.
