Today, P7 found out about the chemical reaction that takes place as we digest our food, with Mr Kennedy at Maxwelltown High. They put small pieces of vitamin c tablets into film canisters, added water then closed the lid and waited…In most cases there was a mini explosion as the lid popped off. Mr Kennedy showed us what happens if a whole vitamin tablet is put inside. The lid exploded off and shot through the air! This shows us the energy we get from nutrients. Energy to keep us warm and help us to  move.

Later, we were shown what happens when ethanol gas is lit at one end of a plastic bottle. The reaction cause sound, heat and movement energy as the bottle flew off. I’m glad we had our safety glasses on!

Thanks to Mr Kennedy. We look forward to visiting again another time.
