Polystyrene spheres are great for all manner of decorative craft activities and model making. They can be cut, glued or painted. Older children could even decorate the polystyrene spheres by pushing in pins with coloured heads or sequins. Try encouraging children to make Christmas decorations, human and animal characters or mobiles. Or how about decorating different size polystyrene spheres to encourage learning about the universe? Polystyrene Spheres are available in several different sizes.
