Today we worked with David from Mobile Science Education to learn all about light. Our new inquiry unit is about light and what we can do with it, how we use it and why the world needs light.

David talked about what light is, how fast it can move, types of light, how we can make light bend and how the human brain uses light to see objects. People can actually only see 3 different colours but our brains work to mix those colours so we see the world with lots of different colours.

Did you know that light travels so fast it can go around the world 7 1/2 times in 1 second?

What was your favourite part of the light show?
