Mainstreaming environmental education in K12 science

Over the past ten or so years, I've been working at bringing a more environmental approach to my high school science classes, while still engaging students in science, technology, engineering and math with appropriate rigor.

I'd like to share some of the things that are working for me, and I'm curious about the experiences teachers of younger students have with teaching science to their age groups. I'm curious - can we imagine a way to create an educational experience for students that has a greater degree of continuity through elementary, middle and secondary grades?
