The vast bulk of elementary school teachers in the United States don't like Science, just as much as they don't like math.
I am *NOT* saying that they are not good teachers. But rather - you're taking someone who probably never really liked those subjects in the first place, and are trying to get them to instill a joy in something that they, themselves, don't have in it to people. It just is not going to work!
Let's look at the elementary school teachers here in the US.. most of them are coming from a liberal arts teaching background. Which is great, because they're expected to teach a plethora of subjects, and also spend the bulk of the day with the students. So they also have the crowd control skills and so on. But ask them in a non-school setting about any basic science - most of them would roll their eyes at the questions, and even tell you that they never even liked it. A lot of them look at science as almost a voo-doo thing, and they just do what's in the textbooks/curriculum.
What really should be done, is to bring in science (and math!) specialists for just those subjects at that level. Let people who have a ready understanding on the material, and who can relate it to every day things interact with the kids for those bits. Let them explain every day things to these kids, to keep the joy of learning there!
Note here: I am an engineer (still consulting) turned Chem/Physics/Math HS teacher in the public sector here in the US. I have also worked these alleged crazy new fangled math stuff that are trying to conceptualize things, when they really need to just go back to basics, and instill basic skills so that the advanced things can be 'fun' , or at the very least be seen by the students as something that they can do, because they already have the tools to do so. Instead of just flat out giving up.
And yeah, we should involve more parental involvement and so on. And oh yes, say it's ok to drop out. Go get a job, and see how awful it truly is without an education - and when their heads are screwed on right - to go get their GED/whatever degree from that point on.. as they'll be self motivated - as opposed to having us to motivate them!
