I want to encourage anyone who is doing a less-traditional approach to science to take great care to document what you do, perhaps keep a portfolio, and make a REAL effort to include true high school level work, including math and labs, WHETHER YOUR CHILD LIKES IT OR NOT, even if they “think” they want to be something that won’t require it. SOOO MANY kids change their minds about career/college, and it is hard to suddenly find that you need some background you don’t have. I know, this has happened to me! (found myself needing to take graduate calculus as a required subject when I’d never gone past college algebra). And, after having gone through the college admissions process, my son was asked a LOT about how we managed science. I wouldn’t have wanted to say “Well, we watched some videos and did a coloring book.” You know what i mean? Make it thorough, make it good, make it high-school-level, (find someone to ask if you don’t know) and document it well. It could make a huge difference to your child down the road.
And I do understand about kids that say “But I don’t like science and I won’t need it because I”m going to be a Lego designer.” I have kids who said “But I don’t need to be able to write an essay because I want to do science.” Well, let me tell you–that didn’t work for my kids! I can actually come up with a lot of reasons for a potential designer to learn real science–just like I came up with lots of reasons for my science-y kids to read novels and write essays.
Don’t Shortchange Your Kids! ! ! ! ! ! They are smarter and more adaptable than you think, the future world looks difficult and broad knowledge base is becoming increasingly important, and biology experiments WILL NOT KILL TEENS. 
Just saying.
