Weathering and Erosion

In Year 5 & 6 the children have been learning about Weathering and Erosion in their Geography lessons. They did some experiments to further their understanding of the different types of weathering. For example, they poured some vinegar on bicarbonate of soda to replicate the chemical weathering that takes place when rainwater lands on limestone. They also discovered that water expands when it freezes, which causes physical weathering.
