Abstract
The contribution presents the proposed content and structure of teaching material (worksheet),that can be used in teaching Integrated Science (especially at the grammar school). For practical documentation of the given general rules, examples from the proposed worksheet on the topic "Chlorine cycle", which is currently reviewed by high school teachers of chemistry, biology, geography and physics, are used.
The worksheet is also used to illustrate the connection between the educational aims of integrated subjects and a new aim. The contribution starts a discussion about what parameters the teaching material for integrated (science) teaching should meet.
