Lesson Plan Day: 40
Teacher: P. Kirk
Topic: Isotopes, differences in mass and different numbers of neutrons,
C.PM: STRUCTURE AND PROPERTIES OF MATTER
C.PM.1: Atomic structure - Evolution of atomic models/theory
HS.PS1.C: Nuclear Processes
Nuclear processes, including fusion, fission, and radioactive decays of
unstable nuclei, involve release or absorption of energy. The total number of
neutrons plus protons does not change in any nuclear process. (HS-PS1-8)
Section 21.1: Nuclear reactions affect the nucleus of an atom.
Section 21.4: Nuclear Fission and Nuclear Fusion
