Juggle fruit. Work on the technology of the future. Plot and design a lost city, create a zoo of invented animals, learn to talk sdrawkcab and bake a pizza clock and a pastry map. How many of our wonderful brain-boosting challenges can you fit into a school holiday? All you need are some art materials, imagination and an enquiring mind to have a go at a whole host of practical and reflective activities, suitable for primary-school children (and parents, of course). Have fun!
