Q1W3: August 26 – August 30, 2019

TeacherJamie Newcomb
Subject AreaComprehensive Science III
Grade Level8
Week #3
Unit of InstructionAtomic Theory and Periodic Table
Standard(s) Taught

SC.8.N.1.1 Define a problem from the eighth grade curriculum using appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.

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.8.E.5.10 Assess how technology is essential to science for such purposes as access to outer space and other remote locations, sample collection, measurement, data collection and storage, computation, and communication of information.

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:

  • collect and organize data
  • interpret data 
  • defend conclusions
  •  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
  • explain that theories may be modified based on new evidence, but are rarely discarded (in the context of atomic theory)


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
