Begin the lesson by discussing the concept of electric forces and how they are created by unbalanced electrical charges in objects. Use the example of rubbing a balloon on hair to create static electricity, which will engage students and provide a practical demonstration of electric force.

Explain the principles of attraction and repulsion between charged objects. Use diagrams to show how objects with the same charge repel each other, while objects with different charges attract each other.

Introduce the concept that electric forces can act at a distance without direct contact, using the balloon and hair example to illustrate this point.

Watch the video 'Electric Charge' to visually explore how objects become charged and the effects of static electricity. This video provides a clear demonstration of non-contact forces and helps solidify the students' understanding.

Conduct an experiment where students rub balloons on their hair and observe the effects of static electricity. Encourage them to note how their hair stands up and how the balloon can pick up small paper pieces without touching them.

Assign students to explore other objects that can be charged by friction and document their observations. This activity allows students to apply their learning independently and discover new examples of electric forces.

Use formative assessment questions to gauge students' understanding of electric forces and their ability to explain the attraction and repulsion of charged objects.

Have students reflect on what they learned about electric forces and how they can observe these forces in everyday life. Encourage them to share their thoughts and any questions they might have.

Assign the 'Non-contact Forces – Comprehension' assessment to evaluate students' understanding of non-contact forces, including electrostatic forces. This worksheet helps reinforce key concepts and assess students' ability to apply them to real-world scenarios.
