Level 3 |
I know that different materials let different amounts of light through. I know that materials that stop light cause shadows to form. I know why objects look dark. I know that some objects reflect light. I know that shaped glass can make rainbows from white light. |
|
Level 4 |
I know that light travels in straight lines unless something is in the way. I can describe what happens to light when it hits different materials using scientific words. I know that white light is made up of a mixture of colours and how to split white light into its colours. I can explain why we see lightning before we hear thunder. I can describe the reflected image in a plain mirror using scientific words. I can describe some ways that colour is important in everyday life. |
|
Level 5 |
I know the role of reflection. I can explain how we see objects. I can explain why objects appear to be different colours. I know that all colours are made from 3 primary colours. I know that filters can absorb some colours and reflect others. I can draw the path of rays of light as they are reflected. |
|
Level 6 |
I know that light bends as it passes from one material to another. I can explain why this happens by using a ‘model’. I can draw the path of rays of light as they are refracted. |
|
Level 7 |
I can relate how shiny a material is to how much light reflects from it. I know that different colours refract by different amounts and I can show this in an experiment. I can use the speed equation to calculate how long it takes light to travel certain distances. I can explain the appearance of coloured objects in different coloured light. |
