    I remember in high school we had to wash beakers with sulfuric acid to make sure there weren’t any traces of heavy metals left.

      At my high school, teachers always said that there’s a biological hazard in the lab (they used the same lab for chemistry, physics, and biology), hence no laboratory class/experience. But that exact lab/room was available and used for teaching classes such as math, history, etc.
