Lesson 3: Can we Make a Telephone?

How does sound travel from one place to another? In this creative Year 4 science lesson from our Sound unit, pupils investigate how sound moves through solids by constructing a simple string telephone. This engaging activity helps children understand that sound travels through different materials using vibrations.

Part of our Scintillating Science programme, this lesson encourages curiosity, hands-on exploration, and the use of key scientific vocabulary. Pupils build on their previous knowledge of pitch and vibration, applying their understanding in a purposeful and memorable way.

This lesson aligns with the Ofsted science subject report by supporting progression in knowledge, practical skills, and meaningful real-world connections.

Included in this lesson:

• Visual teaching slides with questions and prompts
• A detailed lesson plan including key vocabulary and misconceptions
• Differentiated tasks to challenge all learners
• Practical resources to support investigation

A memorable and practical lesson that helps pupils explore how sound travels, bringing science to life through everyday materials and experiences.
