About this worksheet
Year 6 pupils read about how we see in this four-page comprehension. The text opens with the old idea from Euclid and Ptolemy that eyes send out beams. It then says light travels in straight lines at nearly 300,000 kilometres per second. It sorts luminous sources from non-luminous objects such as the Moon, and compares specular reflection in a mirror with diffuse reflection from paper or brick. Ten questions follow, ending with a pitch-black cupboard and a road worker's high-visibility jacket. The answer key gives model answers. Both Year 6 light objectives in the England National Curriculum are covered.
