Physical Science: Matter, Forces & Energy: scope and sequence

Properties of Matter · Phases of Matter · Chemistry · Forces · Motion · Work & Machines · Energy & Heat Transfer · Waves, Sound & Light

Across 36 weeks that is roughly 1.1 lessons and about 1.4 hours a week. A week-by-week calendar for the whole grade is at the Grade 8 year plan.

The units, in order

#	Unit and what it covers	Lessons	Hours
