Light!

In Chestnut Class, we have been investigating and researching light and how the eye works.

With the help of the wonderful Sharmeen, we set up a fair experiment in the sensory room (because this was the only place we could find which did not have other light sources impacting our results!) and we measured the length of shadows when we changed the distance of an object from a light source.

 We discussed the conditions required to make it a fair test. As well as making sure no other light sources interfered with our shadows, we also decided to:

 

¨ keep the distance from the wall the same

¨ Use the same torch

¨ Keep the torch at the same angle

¨ Keep the way we measure the shadow consistent (top to bottom, not side to side!)
