Year 6
Whistle While you Work!
We have been very busy in Year 6 learning about Cornish inventors and in particular Adrian Stephens who was born in Penzance in 1795. He invented the whistle in 1833. The purpose of his invention was to act as a warning device on the boilers. It was a simple safety device to warn engineers when a steam boiler was running out of water which could lead to a rise in pressure and an explosion. It was added to every boiler, railway locomotive and steam ship around the world.
For our Science Day we worked in groups. Each group were given different instructions to follow to make a whistle using a variety of things which included drinking straws, art straws, paper, bottle tops and grass!
We persevered with each task until we made a whistle that worked! Each group rotated so everyone had a go at making each whistle. The results were amazing. Just take a look at us at work.
We also tested different materials to see how long a bubble would last when blown onto it. We blew some great bubbles!! Some of us managed to blow a collection of them!
