Subject AreaScience
Grade Level8
Week #2
Unit of InstructionAtomic Theory and the Periodic Table
Standard(s) Taught

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).
Identify the benefits and limitations of the use of scientific models.
Explain why theories may be modified but are rarely discarded.
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.

Learning Targets and Learning Criteria

Students will:
• recognize that atoms are the smallest unit of an element

• recognize that atoms are composed of subatomic particles:
 Electrons, Nuetrons, and 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)
