Would you know?

According to a story on the BBC today a recent poll shows that most parents could not answer a basic science question from their kids. I find it interesting how these kinds of stories are presented in the mainstream media, I can kind of see their perspective, but these aren't really "science" questions as such, they are questions about how the world works; science is the thing that we use to find the answers. Perhaps this is a pedantic point but framing like this does tend to separate science from "people" IMO, i.e. science is something that boffins in white coats do rather than a thought process that everyone can use to find out about the reality they exist in.

Anyway, here are the three questions they cite as examples of "science" questions, see if you know the answers

• Where do babies come from?
  
• What makes a rainbow?
  
• Why is the sky blue?
  

For the curious here are my answers,

• Babies come from the fusion of an egg cell from the mother and a sperm cell from the father, the cell then divides, and each new cell further divides and so on making more and more cells forming an embryo which then grows over 9 months to form a baby.
  
• Rainbows are the result of (white) light from the sun being split into its constituent colours (wave lengths) as it passes through rain drops.
  
• The sky is blue because air molecules absorb and scatter blue light better than all the other constituent colours in the sunlight which mostly pass through the air unaffected.
  

So, Albert Einstein or Hommer Simpson?
