I think the dichotomy between procedural knowledge and object knowledge is overblown, at least in the area of science. Scientific object knowledge is (or at least should be) procedural knowledge: it should enable you to A) predict what will happen in a given situation (e.g. if someone drops a mento into a bottle of diet coke) and B) predict how to set up a situation to achieve a desired result (e.g. produce pure L-glucose).
