KSI Science Week Blog
Science week got off to a great start with an assembly by Science Boffin Martin. He showed us some amazing effects and reactions, making water disappear in a cup, elephant’s toothpaste—which just wouldn’t stop oozing, and much, much more.
Each class then had a workshop with Martin, in which we explored how dry ice can be used to make ice cream! We mixed our own ice cream and then got to eat it!! Martin showed us some other experiments with dry ice---we all jumped when the lid blew off a small canister!
In the afternoon, Year 1 had an extra treat when Mrs Chadwick came in to do some more science demonstrations on the theme of change. The children were transfixed while we saw clear liquids change colour before our eyes! What an exciting day!
This morning was very busy for Year 1 and 2.
Year 1 were lucky enough to have two scientists from the Sanger Institute to talk about their work. The children did some exciting Hands on work, exploring how germs can be spread(Handshake Hazard) from one person to another just by shaking hands! They used special gel in their hands, and shook hands with a long line of children, finally using a special torch to show how much of the germs had been spread.
They also had the opportunity to look through a powerful microscope, to observe cells.
In Year 2, the children learnt how to separate colours, using chromatography. Many thanks to Mrs Hornigold and Mrs Mannion who came in with some fantastic equipment to do this exciting work.
On Wednesday afternoon, Dr Reynolds came to visit Year 2. We asked her about her work as a research scientist at Barts Hospital in London, and then we had the chance to test different liquids and substances to using red cabbage water, to find out if they were acids or bases.
