An early start
Thinking back to elementary school, I remember that my school focused a lot on making science fun. We would perform experiments, that thinking back were very simple, but as a 4th and 5th grader, they were incredibly interesting. However, there was so much to learn, that it's really difficult for schools, especially elementary schools, to do anything other than wet one's appetite for future exploration in science. For some students, this is enough to keep them interested, and leads them to study science in high school, and into college. But for many others, science just isn't interesting enough to keep the students interested. Unfortunately, it is this way with many subjects in school.
With language, My elementary school would do alternating semesters of Spanish and French, in hopes that it would keep students interested in learning a language. Unfortunately, It didn't work for all students. However, the schools did the best they could with the limited funding and time that they had available to them.
It's unfortunate that not everyone can have the desire to study everything, but realistically, most people just don't have the time, or motivation. Instead we choose early on in life what we feel we are most interested, and with any luck there will still be the opportunities later on in life (such as at college) to explore other subjects, whether they be science, history, of a foreign language.
I am just thankful that I had teachers from early in my education who motivated me to further explore science.
