Lesson details
Key learning points
- Noise is unwanted or unpleasant sound.
- Noise pollution describes levels of noise in an environment that are unwanted or harmful.
- The volume of sound is measured in decibels (dB).
- Normal conversation is approximately 60 dB.
- A decibel scale can be used to find out if sounds should be classified as noise pollution.
Keywords
Sound - We hear sound with our ears.
Noise - Noise is unpleasant or unwanted sound.
Classify - To classify is to sort objects into groups.
Noise pollution - Noise pollution is when sound becomes extremely unpleasant or unbearable and is a problem.

Common misconception
Children may think that any sound is classified as noise, or that only very loud sounds are considered to be noise pollution.
Explain that unpleasant or unwanted sounds are classified as noise. Noise pollution does not have to be loud, it can be an intermittent or continuous quieter noise that becomes a problem.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
