Who wants a million points? - Explain the meaning of terms related to Light - Light - Year 6

In an engaging educational activity titled "Who wants a million points?" designed for Year 6 pupils, students are invited to explain terms related to light, each carrying a point value from 100 to a million. The activity starts with simpler concepts and gradually progresses to more complex ones. For 100 points, students begin by describing 'eyes', the organs that allow us to detect light and therefore see. Next, for 250 points, they explain 'shadow', which is the dark shape created when an object blocks light from reaching a surface.

Moving on to more advanced terms, pupils define 'reflection' for 500 points, which is the bouncing back of light from a surface. For 1,000 points, they describe 'concave', a term referring to a surface that curves inward, and for 2,000 points, 'convex', which is a surface that curves outward. The stakes rise as they reach 5,000 points with 'iris', the coloured part of the eye that controls the size of the pupil and thus the amount of light entering the eye. For 10,000 points, they explain 'pupil', the opening in the centre of the iris. The 'cornea', worth 25,000 points, is the transparent front part of the eye that refracts light. For 50,000 points, pupils discuss the 'lens', which focuses light onto the retina. The 'retina', at 100,000 points, is the layer at the back of the eye that senses light and sends signals to the brain. As the point values increase, so does the complexity; for 250,000 points, students describe the 'optic nerve', which transmits visual information from the retina to the brain. For 500,000 points, they explain the 'speed light travels', which is the constant speed at which light moves through a vacuum. Finally, for the million-point question, pupils define 'transverse waves', the form in which light travels through space. This activity not only tests their knowledge but also reinforces their understanding of the fundamental concepts of light and vision.
