I'm looking for a multiyear science curriculum that I can either use as a homeschooling or afterschooling resource, or recommend to a small school nearby. My kid is young, so I'm most interested in curricula that start in pre-K or K -- high school's a long way off right now. My head is spinning with all these homeschooling resources that are available! Can you help me be lazy? 
Here are some of my criteria:
Am I asking too much? Does something like this exist?
Here are some of my criteria:
- Scientifically correct and rigorous, though age-appropriate.
- Not scattershot across various topics, but carefully and systematically builds on knowledge learned earlier, so that by the middle grades children can start to understand fairly complex topics. (For example, I find that the Boston Museum of Science's curriculum is quite scattershot, with modules that you can apparently do in any order to any degree of depth. I'm not thrilled with that, for my purposes.)
- Teaches plenty of content via well-written readings or lectures. Inquiry, discovery, experiments, etc. are lovely, and we'll do some of that, but it's too inefficient to use for teaching every scientific fact and principle.
- Doesn't patronize children or teachers by being too "cute," too simplistic, or too slow. Kids can understand more than we give them credit for, I think.
- Can be tied into geography, math, and maybe history curricula, possibly with some work on the parent's or teacher's end. I'm okay with doing that work!
- Not Waldorf, as I'm not a fan of anthroposophy.
- Not creationist, as I'm even less a fan of that and its "intelligent design" cousin. (Sorry folks!) Evolution is a fantastic theory, and I plan to teach it.
- Not too heavy on environmental or green ideology. We do plenty of that in our family life; we don't need it in a curriculum too, especially since a lot of issues around energy, resource management, global warming, etc. are profoundly complex and difficult. We'll save that for later. What I want from a young kid's science curriculum is sound scientific knowledge.
