Distance from sounds: do and review
I can carry out and evaluate a fair test about the volume of sounds.
Lesson details
Key learning points
- Scientists often record data from observations and measurements in tables.
- The volume of a sound depends on the distance from the sound source.
- The greater the distance from the sound source, the quieter the sound.
- Scientists often evaluate a completed investigation and suggest improvements.
Keywords
Sound source - An object that vibrates to make a sound is called a sound source.
Volume - The volume of a sound is how loud or quiet the sound is.
Fair test - A fair test is an investigation in which only one thing is changed and another is measured. All other things are kept the same.
Evaluate - To evaluate is to think about what you did and suggest any changes or improvements.
Common misconception
Pupils may think that the volume of sounds are the same no matter how far away from them you are.
Pupils will carry out a fair test to find out for themselves how the volume of a sound decreases with distance from the sound source.
Equipment
Access to sound sources, metre rulers/tape measures and data loggers with sound sensor/sound meters.
