Lenses and Optical Instruments
Introducing converging and diverging lenses, their effect on light rays, and their applications in optical instruments like magnifying glasses and cameras.
Key Questions
- Differentiate between converging (convex) and diverging (concave) lenses.
- Draw ray diagrams to show how lenses form images.
- Explain the working principles of simple optical instruments that use lenses.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
