AP Essential Knowledge
HS-PS1-8 Develop models to illustrate the changes in the composition of the
nucleus of the atom and the energy released during the processes of fission,
fusion, and radioactive decay.
EK 1.B.1 The atom is composed of negatively charged electrons, which can
leave the atom, and a positively charged nucleus that is made of protons and
neutrons. The attraction of the electrons to the nucleus is the basis of the
structure of the atom. Coulomb’s law is qualitatively useful for understanding
the structure of the atom.
EK 1.D.2 An early model of the atom stated that all atoms of an element are
identical. Mass spectrometry data demonstrate evidence that contradicts this
early model.
Essential Questions
(What questions will the student be able to answer as a result of the instruction?)
1. Where did matter come from?
Knowledge & Skills
(What skills are needed to achieve the desired results?)
By the end of this unit, students will know:


By the end of this unit, students will be able to:
Each atom has a charged substructure consisting
of a nucleus, surrounded by electrons.
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.
 Develop a model based on evidence to illustrate the
relationships between systems or between components
of a system.
Assessment
(What is acceptable evidence to show desired results (rubrics, exam, etc.)?
After a brief lesson using the SMART Board to introduce concepts, students will be questioned on these concepts
using the SMART Response system. The teacher will demonstrate the problem solving skills needed for the topic and
again, students will be questioned using the SMART Response system. Students will convene in small groups to
complete problems. Then some students may volunteer to write their solutions on the board and explain their problem
solving process.
