Lesson details
Key learning points
- We can compare different sounds by measuring their volume.
- Data loggers are electronic devices which monitor and record changes in the environment over time.
- The volume of a sound in decibels (dB) can be measured using a data logger.
- Scientists and engineers take accurate measurements to compare and control the volume of sounds.
Keywords
Compare - We can compare objects by looking at what is the same about them and what is different.
Sounds - We hear sounds with our ears.
Volume - The volume of a sound is how loud or quiet the sound is.
Data logger - A data logger is an electronic device that monitors and records changes in the environment over time.
Decibels - The volume of a sound is measured in decibels (dB).
Common misconception
Pupils may think that volume of sound cannot be measured, as they may not have encountered equipment or the units of measurement for doing so.
Allow opportunities to measure the volume of a range of everyday sounds so that pupils become familiar with decibel levels.

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.
