Assessment
- Matter tracing: note if students are able to recognize that the same atoms that were in food are still the atoms in the large organic molecules at the end of biosynthesis.
- Energy tracing: note the ways that students explain how chemical energy is conserved through both digestion and biosynthesis.
- Use 5.1 Grading the Tracing Atoms and Energy in Decomposers Worksheet to grade students’ answers on 5.1 Tracing Atoms and Energy in Decomposers Worksheet .
