Sub-topic: Concept of Electric Charge & Basic Law of Electrostatics
Learning Objectives: By the end of the lesson, learners should be able to:
- Identify the two kinds of electric charges.
- Distinguish between conductors and insulators.
- State the basic law of electrostatics.
Instructional Materials:
- Plastic rod and fur
- Balloons
- Electroscope
- Paper pieces
- Glass rod and silk cloth
Anticipation (Warm-Up): Rub a balloon on hair and stick it to a wall. Ask: "What made it stick? Is it magic or science?"
Building Knowledge:
- Electric Charge: Property of matter that causes it to experience a force in an electric field.
- Types: Positive and Negative charges
- Like charges repel; unlike charges attract.
- Conductors: Materials that allow charge flow easily (e.g., copper, aluminum)
- Insulators: Materials that resist charge flow (e.g., rubber, glass)
Experiment:
- Rub a glass rod with silk and bring it near a hanging paper strip. Observe attraction.
Activities:
- Learners classify objects around them as conductors or insulators.
- Use electroscope to detect charge.
Assessment:
- What are the two types of electric charges?
- Distinguish between conductors and insulators.
- State the basic law of electrostatics.
Homework:
- Draw and label an electroscope.
Expanded Notes:
- All matter contains electrons and protons.
- Transfer of electrons creates imbalance — this causes static electricity.
Differentiation:
- Use real-life charged objects for kinesthetic learners.
- Diagrams for visual learners.
- Guided discussion for verbal learners.
Teacher’s Reflection:
- Did learners grasp the idea of invisible forces?
- Were they able to classify materials correctly?
