Classroom investigations on sun care
The starting points for these classroom investigations are the online activities showing why people need sun protectionand how this can be achieved.
Metal oxides are used in sunscreen because they block ultraviolet rays. These metal oxides are the ‘large lumps’ described in the online activities, that must be in powder form when mixed in a sunscreen formulation.
Children investigate the need and method for obtaining a powder, and look at various ways of testing the effectiveness of the ingredient when mixed into a product.
