This classroom-tested instructional unit was developed to build interest and excitement about the practice of science by real people in real laboratories. It takes learners on a journey to understand how a good experiment is designed, how to recognize bias and error, how to perform an investigation into the natural world, and how to clearly communicate about the findings. It is divided into 15 sections, many of which can be parsed out separately. Topics include scientific ethics, funding for science, research methods, data analysis/interpretation, statistics, error and uncertainty, the peer review process, and understanding scientific articles.
