Can we make a telephone using just string and yoghurt pots?

Let's try it! Can you imagine a world without telephones? The first telephone was created by Alexander Graham Bell in 1876. That's ages ago! Can you make your very own telephone using string and yoghurt pots? Let's plan and take part in a fair test to find out. Use different pots and lengths of string. How will this change the sound?

Follow the step by step instructions on how to make and use your telephone. What do you predict will happen? Good luck with your experimenting.
