IV. PROCEDURES

A. Reviewing previous lesson or presenting the new lesson
Quick recall: Scalars vs. Vectors → introduce Dot/Scalar Product as a bridge to Work.

B. Establishing a purpose for the lesson
Ask: 'Why do we get tired when climbing stairs but not as much when walking on flat
ground?'

C. Presenting examples/instances of the new lesson
Demonstration: lifting vs. pushing an object at an angle; show bungee jumping video.

D. Discussing new concepts and practicing new skills #1
Work done by constant and variable forces (dot product). Work-Energy Theorem with
examples.

E. Discussing new concepts and practicing new skills #2
Gravitational and elastic potential energy; energy conservation (roller coaster example).

F. Developing Mastery (Formative Assessment)
Solve sample problems: Work by angled force, PE-KE conversions, Power climbing stairs.

G. Finding practical applications of concepts and skills in daily living
Energy use in human activities (sleeping vs walking vs running); construction of pyramids.

H. Making generalizations and abstractions about the lesson
Summarize: Work = energy transfer, energy conserved, power = rate of doing work.

I. Evaluating learning
Quiz: Mixed problems on work, energy, and power; conceptual questions on equilibria.
V. REMARKS
Enrichment: Simulation-based activity on roller coaster energy conservation.
Remediation: Extra problem sets for learners struggling with computations.
