Where Does a Plant's Mass Come From?

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.

Revised Version of Student Handout

Submitted by iwaldron on Tue, 03/08/2011 - 7:08am.

This revised student handout provides a more complete set of questions to help students evaluate each of the hypotheses concerning where a plant's organic mass comes from.  In addition, the wording and logic of the questions has been clarified.
