Lesson Overview:
This lesson introduces learners to stationary (standing) waves, resonance, and damping, with a focus on real-life applications. Through interactive demonstrations, guided modeling, and applied tasks, students will explore the behaviour of waves and their practical consequences. Emphasis is placed on recognising scientific principles in everyday scenarios, such as musical instruments, bridges, and vehicle design. Students will apply knowledge, receive feedback, and reflect on learning to build exam-relevant understanding.

Lesson Objectives (Outcomes):
By the end of the lesson, students will be able to:

Identify and describe standing (stationary) waves, including the concepts of nodes and antinodes, and give examples from everyday life (e.g., guitar strings, microwave ovens).

Explain the concept of resonance and describe how it can be useful (e.g., tuning instruments) or dangerous (e.g., Tacoma Narrows Bridge).

Understand what damping is, describe how it reduces vibrations, and explain its importance in practical applications.
