After finding out about Graham Alexander Bell, we decided to make our own telephones.  They worked really well!  We decided to try them outside as it was quite noisy in the class with everyone making calls!

The next day we investigated with bigger cups to see if having bigger ears made you hear better.  The result was that it made little difference to our hearing!  It was a good fun experiment.  

The children have learned so much about Graham Bell, hearing and sound.  Ask them at home!

Next week we are going to have a look at hearing different pitch using bottles and water!
