Sound and Distance - Objectives Labels

In Lesson 4.17, titled "Sound and Distance," students are set to explore the relationship between sound intensity and distance from the source. The objective for the day is to recognise that as the distance from the source of a sound increases, the sound becomes fainter. The lesson is structured to ensure that by the end, students should be able to articulate this concept clearly and confidently.

To assess their understanding, students will be asked a series of questions. They will need to confirm whether louder sounds can travel further than quieter ones, describe how sounds diminish in intensity with increased distance from their origin, and explain the reasons behind this phenomenon. By answering these questions, students will demonstrate their grasp of the key principles governing sound propagation and attenuation over distance.
