Do you know these things?
From the Minneapolis-St. Paul Star-Tribune: Why is the sky blue? Facts you should know.
The quiz doesn’t provide scoring, but the answers are at the end. Bar that I must say I mentally fudged the amount of water (thinking “about 3/4” instead of the precise 71%), and the “sky is blue question” when I just thought “diffusion,” I knew the answers to these, and I’m no scientist.
What about you?
I got everything right, but I thought their explaination was weak for #10.
I found this, which even has an animation of the process of freezing where you can play with the temperature and add salt. Simple, but a little more explanatory that the quiz.
