A simple slice of science – Why is the sky blue?

This week’s question for Dr. Simple came from a source very close to home… my eight year old wants to know

If you have any other questions on this topic or another do leave a message in the comments below. There are lots of great questions coming in for Dr. Simple but he always loves getting more!


If you need a little convincing about all this information on light and colour you can check it out for yourself as I will be sharing some great experiments on tomorrow’s Fun Friday post!

    great post. Simple but easily understood. The funny thing about this question is that I keep forgetting the answer!
