Performance objectives

• and evaluation guide. Both formative and summative assessment strategies will be employed.
• 1. Formative Assessment (During the Lesson)
• Observation: Observe students' participation in discussions and practical activities. Check if they can correctly identify sources of light and reflective objects during group work.
• Question and Answer: Ask spontaneous questions during explanations to gauge understanding (e.g., "Can anyone give another example of an artificial light source?").
• Activity Check: During the reflection and image formation experiments, circulate to ensure students are actively participating and making accurate observations.

Lesson summary

This topic introduces learners to light as a fundamental form of energy. Understanding light is crucial for learners as it impacts their daily lives, from seeing the world around them to understanding basic safety and modern technologies. The lesson explores common sources of light, its various uses, the phenomenon of light reflection, and how mirrors can be used to form images.
