String Telephones

Year 4  are learning about sound in science week. We have watched the internal workings off the ear, learned about sound waves, pitch and volume and looked at the make up of an orchestra and its various instruments. Today we have investigated string telephones, changing just one variable to make our tests fair. Some changed the length of the string, others the size of the cup. Our minds are whizzing with scientific questions!
