Warm-up: View the TED-Ed film “The law of conservation of mass” using the
following link: https://youtu.be/2S6e11NBwiw
After watching, answer the two questions below
1. Why does the equation CO2 + H2O -> C6H12O6 + O2 violate the law of
conservation of matter?
2. How does Einstein’s famous equation E = mc2 relate to the law of conservation
of matter?

Explain how the
law of conservation
of energy applies to
transfer of energy
between forms
Apply the law of
conservation when
calculating the initial
versus final energy of a
system, accounting for
potential differences
through transformation.
Apply data and further
concepts of scientific
research to show
efficiency in energy
conversions.
