Our topic in Science this half-term is materials and we have been looking at rocks. First we looked at different types of rocks and then we carried out our own rock erosion experiment. First we collected rocks from our playground then we brought them back to class. We put the rocks in water and each took our turn to shake them as hard as we could!
After a while we poured the water and the rocks through a sieve to see what had happened to them. We noticed that some of the sediment in the rocks had worn away and this helped us to understand that rocks can change over time and that the weather can erode them. Some of us even realised that there rocks were so crumbly that they must have been sedimentary!
Well done Class 3!
