In this project, we worked in partnership with school teachers who are frequent users of experimental kits available for loan to schools using the historical-investigative approach. The original kits bring a traditional approach to experimentation, without the presence of the history of science. We developed and implemented new guides to the kits, without changing their materials and instruments. Design-based research supports the development methodology; the school science topics covered in this paper are Joseph Black's studies on latent and specific heat. Although some of the challenges faced in the implementation of historical-investigative approach are known and well-documented, the present article addresses teachers' perspectives and some of the problems they faced in the implementation process, most of them related to school and teacher working conditions. Even though this is a case study with a small number of schools and teachers, it is possible to say that there is a huge gap to overcome before the historical-investigative approach can be implemented in large scale.
