The nice thing about science at this age is that you can go for either breadth or depth and supplement very easily. We found an awesome set of chemistry and biology books at the public library, for example. While they are talking about plants on a very basic level in his grade, he is happily thinking thoughts about what he has read, and relating them to the things the teacher is saying. Sometimes this results in oddly advanced or off-topic contributions to the class discussion, but that hasn't been a huge problem in the scheme of things.
I find this quite different from math, where it's mastered or it isn't. Obviously, it would be better for them to offer the deeper curriculum across all subjects, but for our very science-oriented DS the science has been less of a frustration than the math has been.
