Grade 8 Physical Science-Unit 5
Stage 1: Desired Results
Enduring Understanding
The smallest unique particle of matter is an atom and atoms can combine physically and
chemically.
Correlations
Unifying Understanding
Our perception of the modern model of the atom has developed
over time and allows us to make predictions about how chemicals
will act when combined.

Knowledge and Skills
Students should know:
•
History of development of model of atom from Democritus to modern model
•
Definition of atom and characteristics of its parts
•
Difference between an electrically neutral atom and a stable atom
•
How atoms gain, lose and share electrons to become stable
