Opal Class have begun their new topic in Science – Light!
Before our experiment, we discussed how darkness is the absence of light.
We looked inside a cardboard box to see if we could identify the mystery object. Slowly, we let in more light. We thought about where the light entered the box and how that affected our visibility. We then used a torch, first shining through a hole on the side of the box, then on the top of the box. We discovered that because light moves in a straight line, when the torch was shining through the top of the box, our visibility improved and we were able to identify the object.
How does the position of the light source improve our visibility in real life? Think about where we put lights in our house and lamp posts on the street.
