1. Light Activities KS2 Education & Cultural Services Department Ripple Effect (Year 3 to 6) The ripple effect is an idea whereby you create a set of events which trigger off other events, and the children have to foresee what could be the consequences and how they could minimise the risks – a bit like a risk assessment but more interesting. The idea can be used throughout science and is a tool for teaching scientific knowledge.

2. Consequences—What Could Happen Next? Mr.Jones has made some serious mistakes in his house. Read his story carefully! Mr.Jones keeps meaning to fix the fuse box for the electrics but keeps forgetting. He has some battery-powered lamps which he uses in case of emergency, but he hasn’t tested the batteries for over a year. Mr.Jones has some candles in his bedroom next to the pile of papers which need to be sorted out. The matches have been left downstairs from his sons birthday party. The street lamp outside his house is not working, and the council are coming round tomorrow to fix it. The television in Mr.Jones’ house isn’t working properly, and only has a black screen when you turn it on. His emergency torch is downstairs in the cupboard under the stairs. The moon can hardly be seen tonight. The cat always sleeps on the top step of the stairs. Mr.Jones’ son left a toy car on the floor downstairs. The phone is downstairs in the lounge. One night, Mr.Jones thinks he can hear noises from downstairs. He decides to go and investigate. What might happen ?

3. Light Activities KS2 Education & Cultural Services Department Shadows (Year 4) L3 – Explain that shadows are formed when light from a source is blocked. L4 – Make predictions about the shadows formed by different objects and materials. Give the children a set of objects. Tell them they are going to use them to make shadows. Ask them to draw what shape they think the shadow will be. Then they project the shadow with a torch or OHP and see if they were correct. They could turn the object around to see if they can get it to match the shape they predicted.
