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.
