This week we have been learning about how rivers change from source to sea. We studied the River Tees. We learned how waterfalls form by looking at photos of High Force. The soft rocks get eroded then the overhang falls so the river flows through a gorge. At the base of a waterfall is a plunge pool which can be very dangerous!
In science, we are learning which materials are the hardest. We predicted which materials could be scratched by a nail then we tested them. Have a look at our pictures…Natan found a different property when he looked through a perspex cylinder!
