Professor Bunsen

On Tuesday, we were visited by a very clever scientist, who goes by the name Professor Bunsen.
He told the  Middles all about physics and chemistry and showed us many different experiments. Some of the things we did look like magical tricks, but Professor Bunsen explained the science behind every thing he did.

Some of the things we learned include:
I learnt that when you rub a balloon on thin hair, your hair will spike up and then if you get some tinsel and put it in front of the balloon, the tinsel floats up because of the build up of energy -Tessa
I learnt how air is so important and why we need it. We need air because we need to be able to open containers. I know this because Professor Bunsen took all of the air out of a container and it was impossible to take off the lid - Amber

Professor Bunsen said that if you are a scientist you never say, “impossible”. I also learnt that cotton is very flammable – Riley

With different chemical you can make different colours. I also leant that ping pong balls are made of cotton, not plastic – Dan S

If you put water in a bowl and then fill the rest of the bottle up with air, then overfill it with air, it will fly high in the sky and it will have a cloud inside. Ping pong balls are the only thing that’s explosive that’s allowed at the Olympic Games – Matt G

Chemistry isn’t about overflowing, bubbly things, it’s about chemicals, reactions, solids, liquids and gases - Laura

Chemistry is basically in everything – Gemma

A nappy is made of lots of chemicals and if you put turmeric and detergent together it changes to blood! – Ciaran

If you have one cup of hot water and one cup of cold water and you get a special fan in the cups it will generate power – Joe
