Our irreversible changes topic took us outside too!
Here we used our knowledge of chemical reactions to create some rockets!
Rocket 1: Place a fizzy vitamin tablet and water in a camera film container. Put the lid on and …..pop!
Rocket 2: Place some bicarbonate of soda and some vinegar in a camera film container. Put the lid on and …..pop!
Rocket 3: Place some more bicarbonate of soda and some more vinegar in a 2 litre pop bottle. Hold your hand over the top 0f the bottle while the gas builds up and ….. whooooooooshhh! (you’ll stink of vinegar!)
Rocket 4: Place a Mentos mint in a bottle of Coke and …..whoosh!
