Abstract This paper carried on the teaching design from the view of elements,and had turned the teaching emphases of the knowledge of element compounds from the fact knowledge memorizing to the understanding of more fundamental chemistry concepts and their cognitive ideas and methods.The lesson of “the production and use of nitrogen fertilizer” took four inquiry tasks of “transformation of containing nitrogen substances” as a clue,highlighted the teaching design which based on “the view of elements”,helped students to complete the construction of knowledge and the formation of chemical ideas.
