Background support in the teacher's manual is the only acceptable answer. Providing the student training in science methodology should be done explicitly. Since science is the method used to discover new knowledge and disseminate it to others, this will help them in all subject areas for the rest of their lives. Actual lessons should be designed where the dominant theme is the exercise of the science methodology. Discovery is seldom stumbling over a piece of gold.
Society exists in a cooperative environment , so does science.
I stood on the shoulders of giants who preceded me. All scientists share their work, even when they are working alone. Peer review is the basis of all science. The goal is the accumulation of knowledge, not funny ideas. The cooperative advancement of knowledge makes all of what our civilization has achieved possible.
