In Science this week, as part of our investigation into how light travels, we conducted an investigation of reflecting light.
The children were given some equipment (a torch, a mirror, a piece of card with a slit in it, a protractor and a piece of plain paper) and were asked to consider how to use this to prove the law of reflection. There were lots of interesting ideas and we eventually looked at how we could do this as a class.
Using the torch, we shone a beam of light through the slit in the card onto the mirror at an angle. We marked the angle of incident (where the light travelled towards the mirror) and the angle of reflection (the same light beam reflecting off the mirror) and then used a protractor to measure these angles.
We were able to prove the law of reflection and the children understood that the angle of incident was equal to the angle of reflection - some seriously scientific stuff!!
