Both Primary and Secondary School participated actively and enthusiastically in this year’s national Science Week which ran from 12-19 November. Each class in Primary School worked on a particular experiment on the topic of heat exchange and they all presented their experiments at a Science assembly at the end of the week.
The highlight in Secondary School was Mr Earls experiment with 7th class: they blew up some watermelons by adding solid carbon dioxide (at -78 degrees Celsius – that’s as cold as some of the nights on Mars!) to water in a bottle. This caused the carbon dioxide to rapidly change from a solid to a gas. They then sealed the bottle and let the pressure build up. When the pressure got too high for the bottle…BOOM! The bottle and watermelon exploded into pieces.
