The Cuddly Koalas children explored and investigated the beauty of painting on a vertical and see-through film surface. First, we distinguished colours with the children. Each child received one recycled egg carton with tempera paint and a brush. Then, the children stood in front of the see-through surfaces and were challenged to make marks on the surface to the best of their abilities. In the meantime, the children listened to The Four Seasons by Antonio Vivaldi.
