We were talking about renewable and non-renewable sources of energy.
We also learned about the history of light through the ages (from basic fire torches to candles to light bulbs to energy saving light bulbs.)
We had some interesting questions which we were able to answer with the help of the light box in our classroom.
We used a light box to investigate these questions and we found that:
Yes, we need light to see. In a completely dark box we can’t see Lucky Duck (our fluffy) toy, or a mirror or star (reflectors).
We were able to see the light up stone (which is a light source).
We are now pretty sure that shiny objects are not light sources since we can’t see them in our box. This makes sense since we can’t see ourselves in the mirror if our rooms at home are totally dark.
We also learned the difference between objects that are reflectors and those that are light sources. Can you tell the difference?
We have a better understanding now of light sources and reflectors.
We know the biggest light source (sun) and biggest reflector (moon).
