As part of our learning about the water cycle and rivers, we made our own V-shaped river valleys! We balled up paper balls, and arranged them in a zig-zag formation. Then, we used mod-podge to build up a layer over the paper balls. We took special care to ensure that the path of the river was visible. Once that had dried, we covered our models with a mixture of PVA glue and water, and then built up the landscape with strips of tissue paper.
