I mean this is just... Incorrect. High school chemistry (generally the first time it's called chemistry and not science) is often taught in a lab (I assume mainly a function of whether lab facilities are available). Undergraduate general chemistry and organic chemistry generally have a required lab component that is required to be taken concurrently (this is even true at community colleges). Using general chemistry as an example, the lab portion is usually 1 three hour (at least) class per week, while lecture is 3 one hour classes per week (organic chemistry is essentially the same). More advanced chemistry might not have lab components (e.g. physical chemistry), but the foundations are almost always at least combined with a lab.
