In expedition today, the children carried out various tasks in order to compare and group different types of rock.
First they grouped them into 3 major rock types; Metamorphic, Igneous and Sedimentary.
They then placed the rocks into a bucket of water to see if there would be any changes in their physical properties once the different rocks were in water. Which rocks would have high or less density? Will they float or will they sink?
They observed that the physical properties of the Sedimentary rocks, such as chalk, sandstone and Oxford clay, had changed.
They used sandpaper to help them discover which rocks were hard and which were soft.
The children then recorded their findings onto their charts.
Who’d have ever thought you could learn and have so much fun with a pile of rocks!!
