As a homeschooling parent of four kids who have done a lot of science over the years (my eldest ias graduated high school now) I have not ever found such a comprehensive book or program that I feel is worth the paper it's written on. The grade-levelled stuff tends to be so shallow and superficial as to be useless for kids with even a vague interest in things scientific. If it's at a high enough level to have a depth of content it's too dry and/or laden with written work for a younger child. My dd9 has been using a program like this through our school district's homeschooling umbrella program; to find any new or interesting information we've had to go four grade levels ahead. We mostly skip the units in her areas of particular interest because the material is stuff she's already more than familiar with. In areas she hasn't learned much about we end up ditching more than half the written work, because she just doesn't have the stamina expected of 7th graders... and it's pretty dull stuff for the most part. Most of what we do for science has to be outside the realm of the curriculum, or else she'd start finding science to be pretty boring. And I don't want that, because she currently loves science and has a wonderful scientific mind.
What we end up doing is gleaning resources that are not grade-levelled, based on my kids' particular interests. Not curriculum, for the most part. Typically books written by creative scientists interested in sharing their passions with young people. Or documentaires, or real-life applications of science. Because science covers everything from geology to theoretical physics to animal behavior to genetics, you don't find passion and creativity spanning all those areas in a comprehensive way. Although it's more work for the parent, I've found that the best way to raise a keen little scientist is to help your child with the exploration and discovery process on a topic-by-topic basis. After all, that's what science is in practice... encountering things that make you curious, asking questions about your observations, and seeking answers.
Maybe I'm misunderstanding what you're asking for, because I don't think what you're asking for could exist. In what way could science be made "linear"?

When you learn anything you start small and expand upon. That's what I mean but linear, starting at 1 and moving up. She knows a lot of facts about animal biology & human biology. She is also interested in Astronomy & Geology. On top of that she loves plant life & dinosaurs. It goes on and on and on. Obviously she wants to learn all of this. Of course I am going to need multiple texts to give to her. I am sure there is a text out there that explains in great detail how to introduce a young child to the world of science. I am not a science teacher but maybe I need to consult an actual teacher of the subject or texts designed for the teacher because that's a lot different than what I am getting here. If she were in classroom at school with a science teacher allowing her to guide him in whatever direction she wanted to go or learn about , I am sure he would be full of information that he could expand upon, and probably would have a wealth information in some reference material. That's what I am looking for, thanks for helping me get to that realization.
