Q1W2: August 19 – August 23, 2019

TeacherJamie Newcomb
Subject AreaComprehensive Science III
Grade Level8
Week #2
Unit of InstructionAtomic Theory and Periodic Table
Standard(s) Taught

SC.8.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).

SC.7.N.3.2 Identify the benefits and limitations of the use of scientific models.
SC.8.N.3.2 Explain why theories may be modified but are rarely discarded.
SC.6.N.2.2 Explain that scientific knowledge is durable because it is open to change as new evidence or interpretations are encountered.


SC.912.P.8.4 Explore the scientific theory of atoms (also known as atomic theory) by describing the structure of atoms in terms of protons, neutrons and electrons, and differentiate among these particles in terms of their mass, electrical charges and locations within the atom. 



Learning Targets and Learning Criteria

Students will:

  • discuss the VARIOUS methods used by scientists to answer questions or solve problems (controlled experiments, observational studies, engineering by design, trial and error, simulations, modeling, etc.)
    • engage in a lab where students:
      •  form a hypothesis
      •  follow a procedure using repeated trials
      •  collect data, take measurements, analyze and interpret graphs
      •  draw a conclusion based on evidence
      •  use phrases such as “results support” or “fail to support” their hypothesis/claim (NOT PROVE OR DISPROVE) and how it leads to further investigations (revise and repeat)
  • recognize that atoms are the smallest unit of an element
  • recognize that atoms are composed of subatomic particles: Electrons, Neutrons, Protons
  • create a model or diagram of an atom (nucleus and subatomic particles)
  • discuss the benefits and limitations of various atomic models o NOS Focus- benefits and limitations of models
  • explain that theories may be modified based on new evidence, but are rarely discarded (in the context of atomic theory) 

Advanced: Explain that electrons, protons and neutrons are parts of the atom and that the nuclei of atoms are composed of protons and neutrons, which experience forces of attraction and repulsion consistent with their charges and masses
