Year 2 enjoyed a fantastic day at the Glass Centre, combining both Science and Art & Design.
In the morning, the children carried out 3 Science experiments:
- Firstly, they investigated what would happened to salt when added to water. They made an initial prediction before finding out that salt is soluble and dissolves in water.
- They then carried out a similar experiment but this time using glass frit. They discovered that glass frit is insoluble and does not dissolve in water.
- The children then discussed the difference between a solid and a liquid and identified various examples of these. They learnt that glass is made from sand, soda and lime and that these ingredients need to be heated to 1100 degrees celsius to make molten glass. Once cooled the liquid turns into the solid glass that we see around us everyday. To investigate solids and liquids further, the children made a mixture using corn flour and water and found that it is unusual in that when pressure is applied to the mixture it acts as a solid but when it is left it acts as a liquid. The children knew this as Oobleck but the scientific name is Non Newtonian fluid.
After working scientifically in the morning, the children had worked up quite an appetite and devoured their tasty lunches.
The children’s artistic side shone out in the afternoon, when they designed and created fused glass tiles. The children did a superb job – some of the tiles were very colourful with lovely repeating patterns, flowers and hearts while others depicted some lovely seaside scenes and lighthouses. The tiles need to be fired in the kiln so will be ready for the children to take home from school after the holidays.
The day ended with a glass blowing demonstration, which was met with lots of oohing and aahing!!
