Engaging Start to a Science Lesson on Electromagnetism: The Electric Motor

Introduction

To ignite curiosity and engage your Year 11 students in the fascinating world of electromagnetism and electric motors, we will start the lesson with an interactive demonstration that sparks their imagination and prompts inquiry.

Setting the Scene: The Mystery of Motion

Objective

Begin the lesson by creating a sense of wonder about how electric motors impact everyday life. Use a simple electric motor to demonstrate motion and force, while encouraging students to think critically about the underlying principles of electromagnetism.

Materials Needed

• A small DC electric motor
• A battery (AA or 9V)
• Connecting wires
• A small handheld fan blade or a piece of cardboard shaped like a fan blade
• A clear glass jar or transparent container

The Demonstration

1. Preparation: Set up the electric motor with the fan blade attached to its shaft. Connect the motor to the battery, ensuring safety with the wiring.

2. Dramatic Entrance: Dim the lights and place the motor inside the glass jar. This adds an element of mystery—students will be curious about what happens next.

3. The Reveal: As you power the motor, watch the fan blade start spinning. As it gains momentum, the energy in the room will shift from curiosity to excitement.

4. Mystery Question: Once the demonstration is complete, pose the question:

   • "What makes the fan blade spin? How do we harness electricity to create movement?"

Encouraging Inquiry

Group Discussion

Divide the students into small groups and ask them to discuss their thoughts and hypotheses about the following questions:

• What do you think causes the motion in the electric motor?
• Can you identify any devices in your lives that use similar principles?
• How does electromagnetism play a role in this process?

Concept Introduction

After the discussion, bring the groups back together and facilitate a class-wide discussion to pool their insights. Introduce key concepts of electromagnetism and the basic working principles of electric motors, highlighting the role of magnetic fields and electric currents.

Conclusion

This engaging start to the lesson not only captures students' attention but also sets a solid foundation for deeper exploration into the topic of electromagnetism and electric motors. By experiencing a demonstration first-hand, students will be more excited and prepared to learn about the scientific principles that power the devices around them.
