NSES Content Standard Unifying Concepts
and Processes:
Constancy, change, and measurement Grades K-12, page 118 Energy can be transferred and matter can be changed. Nevertheless, when
measured, the sum of energy and matter in systems, and by extension in
the universe, remains the same.

Benchmark 4E The Physical Setting: Energy
Transformations
Grades 9-12, page 86
Whenever the amount of energy in one place or form diminishes, the
amount in other places or forms increases by the same amount.
Benchmark 5E The Living Environment:
Flow of Matter and Energy
Grades 6-8, page 120
Over a long time, matter is transferred from one organism to another
repeatedly and between organisms and their physical environment. As in
all material systems, the total amount of matter remains constant, even
though its form and location change.
Benchmark 11C Common Themes: Constancy
and Change
Grades 9-12, page 275
Along with the theory of atoms, the concept of the conservation of
matter led to revolutionary advances in chemical science. The concept of
conservation of energy is at the heart of advances in fields as diverse
as the study of nuclear particles and the study of the origin of the universe.
