Science literacy is not about being able to solve all the equations or being able to come up with Einstein's theory of relativity; it's about figuring out how science impacts your world every day. Just the way you need to be reading-literate, or you need to have mathematics so you can balance your checkbook or understand prices when you go to the store.
You see statistics in the newspaper about what's going on with your health care; doctors give you choices and you have to make decisions; we have referendums put on ballots (things like organic food or not), so there's a level of science literacy that's needed, aside from whether kids grow up to have careers in science. But science literacy also fills the pipeline with those students who will go on to become professional scientists
