To help us understand how sound travels, the children made their own **string telephones**. Working in pairs, they used cups and string to test how sound moves from one place to another. They discovered that when the string is **tight**, the sound travels clearly, but when it is loose, the sound becomes much quieter. Through this hands-on activity, the children learned that **sound is made by vibrations**, and these vibrations can travel through materials like string. It was a fantastic lesson, with lots of excitement, curiosity and great use of scientific vocabulary!
