This analysis and discussion activity helps students to 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. This activity is aligned with NGSS standards. For example,students engage in analyzing and interpreting data and arguing from evidence.
