This week in Science Club, students explored how chemical reactions can be used to power rockets into space. Using vinegar (an acid) and sodium hydrogen carbonate (an alkali), they observed the reaction that produces water, carbon dioxide gas, and acetic acid. As the gas built up in a sealed bottle, pressure increased until the rubber bung was forced off – launching the bottle into the air!
The students experimented with different variables, testing 1-litre versus 500ml bottles and adjusting the amounts of vinegar and sodium hydrogen carbonate. Their observations and careful testing showed great scientific thinking and problem-solving skills.
The second activity involved creating a planetary mobile. Students used polystyrene balls of various sizes, painting and assembling them to represent the planets. Due to drying time, the mobiles will be completed next week.
Fantastic work, well done Science Club!
