New Weds Feature – Why is the Sky Blue?

Here is a little nerdy quiz to take the place of the quote feature. I will be posting the answers Friday. This is from the Star Tribune in St. Paul, Minnesota

Think you know you know your science? Recently, several science gurus — Nobel Prize winners, institute heads, teachers and others who spend most of their time thinking about science — were asked, “What is one science question every high school graduate should be able to answer?”

Take their quiz and see how you do.

1. What percentage of the earth is covered by water?

2. What sorts of signals does the brain use to communicate sensations, thoughts and actions?

3. Did dinosaurs and humans ever exist at the same time?

4. What is Darwin’s theory of the origin of species?

5. Why does a year consist of 365 days, and a day of 24 hours?

6. Why is the sky blue?

7. What causes a rainbow?

8. What is it that makes diseases caused by viruses and bacteria hard to treat?

9. How old are the oldest fossils on earth?

10. Why do we put salt on sidewalks when it snows?

Extra credit: What makes the seasons change?

If you dare, post one or more of the answers (or your guess;)! I haven’t even given NerdDad the quiz yet!
