Scotland Class were looking at the properties of different rocks in Science this week. They explored how brittle the rocks were, whether they sank or floated and also whether acid (they used vinegar) caused a chemical reaction when it was applied to the rock. They discovered that the clay was brittle, the sandstone and granite was hard and all of the rocks sank when they put them in water. The clay was the only rock that changed when vinegar was applied to it. They had lots of fun carrying out the tests and learnt even more about rocks.
