Banjarmasin city environment is one of the environments with potential wetlands that can be used as a source of learning in the subject of fluid physics so that the development of teaching materials based on the wetland environment is deemed necessary to be developed. This study aims to describe the practicality of fluid physics teaching materials based on wetland environments. This research is a research and development, in which the researcher has developed a teaching materials with a valid category and will then see the practicality of the tool after field testing. The research instruments used is in the form of the lesson plan implementation sheet and student response questionnaire. The developed teaching materials are assessed for practicality through observation of the implementation of the lesson plan and through filling out the student response questionnaire. The results of the analysis showed that 1) the implementation of the lesson plan received a score of 3.13 in the practical category and the results of the student questionnaire received a score of 3.19 in the practical category. It can be concluded that the fluid physics teaching materials based on the wetland environment is categorized as practical, so it could be used for the next development stage.
