Benchmark 4E
The Physical Setting: Energy Transformations
Grades 9-12, page 86

Different energy levels are associated with different configurations of atoms and molecules. Some changes of configuration require an input of energy whereas others release energy.

NSES Content Standard B 
Physical Science: Transfer of energy 
Grades 5-8, page 155 
In most chemical and nuclear reactions, energy is transferred into or out of a system. Heat, light, mechanical motion, or electricity might all be involved in such transfers. 

NSES Content Standard B 
Physical Science: Chemical reactions 
Grades 9-12, page 179 
Chemical reactions may release or consume energy. Some reactions such as the burning of fossil fuels release large amounts of energy by losing heat and by emitting light. Light can initiate many chemical reactions such as photosynthesis and the evolution of urban smog. 

NSES Content Standard C 
Life Science: Matter, energy, and organization in living systems 
Grades 9-12, page 186 
The chemical bonds of food molecules contain energy. Energy is released when the bonds of food molecules are broken and new compounds with lower energy bonds are formed. Cells usually store this energy temporarily in phosphate bonds of a small high-energy compound called ATP.
