Lesson Two – String Telephone

This science teaching pack for Key Stage Two gets the children to practise devising and producing a working model to illustrate and record how sound can be created through the vibration of different materials.
The class can draw and label a scientific diagram to explain how sound travels through materials using vibration when building a model of a string telephone to test the concept.
Download this teaching pack including a lesson plan, classroom activities and an interactive presentation to practise devising and producing a working model to illustrate and record how sound can be created through the vibration of different materials
Activities in this teaching pack include display posters to identify and explain how to use vibration to make sounds and a shared reading text to practise making a model of a string telephone to illustrate how sound can be created through the vibration of materials.
The interactive presentation can be used to explore how to to illustrate and record how sound can be created through vibration.
This lesson is part of a science scheme of work to get the children to identify how sounds are made by vibration, investigate ways of changing pitch and volume and test how some materials can be used for soundproofing. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
