Why is the Sky Blue? Why do Fish Live in Water?

Children can be very inquisitive, often asking very good questions, and it's easy to brush off or ignore ones we can't answer, but if they ask a question that you don't know the answer to, seize the opportunity to explore the topic and both you and your children will learn something new!

The internet gives us the most amazing resource imaginable - at our fingertips are the answers to almost any question on the planet, and certainly to any questions that our children will pose!  If a challenging question comes your way, take time to research the answer, and encourage the inquisitive, learning nature of your little ones.

The internet is not the only resource at hand.  Perhaps a question might lead to a trip to the library, a museum or the zoo?  You don't have to answer just a single question, take the time to explore the topic area more broadly and that way your children will learn so much more.  Young children absorb facts in an astounding way, but they also need to hear the conceptual reasons behind something as they build up their knowledge and understanding of the world more broadly.

Of course, your children won't understand scientific reasoning behind complex answers, your job is to couch  explanations in terms that they will comprehend.  Reference things that they do understand, and explain things using examples and experiences from everyday life that your little ones will understand.

Well, why is the sky blue and why do fish live in water?

The sky appears to be blue because air molecules scatter more blue light than other colours, until the sun sinks on the horizon at which point the light is coming indirectly and more red, yellow and orange light is scattered, sometimes leading to glorious sunsets!

Fish don't have lungs, but gills - these have developed to filter oxygen out of water rather than taking oxygen from the air.

Now, try explaining those in terms that a four year old will understand!
