Today in science we explored how rocks and fossils change over time. We began the lesson by thinking about whether rocks change over time as we discussed a large granite rock that Mr Campbell had brought to show us. Next, we discovered how a rock could be made to change through weathering and erosion as we watched an animation of how rocks change over a period of time. We then conducted our own investigations with Samuel volunteering to be a rock and Mr Campbell using a hairdryer to adopt the role of the wind. This enabled us to see the process of weathering as the post it notes flew from Samuel's head and shoulders. Finally, we gathered stones from outside and brought them into the classroom to see how they would react when placed in water for a brief period of time. We discussed how over many years small fragments of the rock break away from the rock face before eventually turning to sediment and forming new layers of rock at the bottom of the sea.
This afternoon was lots of fun!
