In class we made model volcanoes using a plastic bottle, card, lots of scrap paper and coloured tissue paper. We then exploded them outside by mixing hot water, fairly liquid, bicarbonate of soda and vinegar. A chemical reaction took place and CO2 was released. Co2 is a gas which is released during real eruptions. In class we then discussed the variables we would change next time to observe changes in the flow of the ‘lava.’
Looks like great fun!
Your volcanoes look fantastic Primary 7! Well done. Looks like you all had great fun watching your science experiments come to life and erupt like a real volcano 🙂
Those volcanos look so so amazing and awesome! Well done to all of you. I hope all of you had great fun making and erupting your awesome volcanos. I would of loved to make one as well Primary 7. They all looked fun to make!
