… top idea we did for Science Week – take about 3m of garden hose (so a 15m length will do about 5) and make cone shaped card cone thingies at either end (preferably different colours so red can be the listening end and blue the speaking) and then attach with gaffa tape.

Get the kids to whisper down one end and listen at the other and they’ll have hours of fun. You can, if you feel confident, explain the basics of sound waves and telephone systems…
