In Room 10 we have been learning about energy and forces. We have been investigating light.
First we brainstormed things that give us light. We call these light sources. We learned that the sun is the biggest light source in our galaxy.
Light sources: fairy lights, a torch, light bulbs, candles, safety lighters.
Then we learned about things which reflect light. We call these reflectors.
Reflectors: tinfoil, mirrors, high visibility clothing, medals, coins, DVDs.
We learned that reflectors don’t light up themselves – light sources shine onto reflectors and the light bounces off them, making them look shiny.
We learned that the moon is a reflector. It doesn’t really shine – it reflects the light coming from the sun.
We brought in objects from home and tested them to see if they reflect light. Some of the objects were reflective, but some were not.
The jewellery box was reflective.
The envelope was not reflective.
We also learned about things that are transparent. If something is transparent it means you can see through it.
We brought in things from home which are transparent.
Transparent objects: ziplock bags, make-up bags, plastic bottles, water.
We investigated the transparency of the following items: paper, tissue, tinfoil and greaseproof paper. First we predicted which ones would be transparent and which would be non-transparent or opaque. Then we tried to trace a picture through each of these materials.
Here are our predictions and our results.
Here is a gallery of all of our investigations.
