Remedial Science Education

So, my science education sucks.  Like, I went to a creationism school until 8th grade, so I'm missing some serious basics.  And the education was book learning only, so few field trips, no microscopes, no experiments, no anything.  I took chemistry, physics and biology in high school, but they didn't really sink in and I could get by with memorization for those.    And then I took wimped out in college and didn't take my science classes at my school where I might have actually learned something.  

This hasn't really been an issue until the Rhymer got old enough to ask a lot of questions.  And I'm embarrassed having to defer the questions about evolution and botany to his dad.  

I follow some science people on G+ and it's tough even reading pop science because I'm missing so many basics.  So, where the hell do I start?
