Year 2 had an excellent day today when they visited the Glass Centre in Sunderland. The visit was linked into our Science topic of Materials and the children were Scientists for the day - in the morning they carried out 3 investigations and watched a glass blowing demonstration and in the afternoon they made their very own fused glass tile.
In the first investigation the children added salt to water to see what would happen - they found that salt is soluble and dissolves in water. They then added glass frit to water to see what would happen - they discovered that glass is insoluble which means that it does not dissolve. In the final experiment the children added water to cornflour to see what would happen - their findings this time were quite unusual. The flour and water mixed together and when pressure was applied to the mixture it acted as a solid but when left alone it was a liquid. The name for this type of mixture was non-Newtonian fluid.
Here are some photographs of the young Scientists at work.
