Rather frightening how many people didn't know most of the answers.

11 for 12. I surprised myself.

I was pretty sure I was right, but I wasn't positive.

I have to say that much of what I learned about science wasn't in school. I'm talking about elementary school curriculum. My parents bought us Time-Life books for kids. Sort of a child's encyclopedia series. My brother and I read each book, cover to cover.

That was a million years ago. I hate to think what is left out of science education now.

In the late 1990s, my little cousin was in elementary school in Benton, Kentucky. His class was told to rip out the pages of their science book that taught about the big bang theory.

There was some, not much, but some, backlash. So the next year, they were told to glue the pages together.

This was a public school.

Pretty simple, but the tide one is tricksy unless one understands a bit about gravity and tides. It's that 1 over r-squared factor.

I forgot how old I am and never attended any form of school .

I got all of them right, but i had to do it twice because i got some error (i think it was a703 error) when it went to retrieve the answers. I answered everything the same both times. Once it got an error, the other time i got a score.

It's an ok test. I can see someone not in the sciences not getting all of them, though. Some are tricky.

Who developed the polio vaccine is more about history than science.

The magnifying glass question should specify which side of the glass the light enters from. It may not converge from one direction.
