The time pupils spend at school provides a very small benefit to pupils’ movement activity. At a time when many school-age children lack physical activity, it is necessary to think about how to integrate more movement into the period that the child spends at school. The paper is based on the assumption that outdoor education can contribute to the development of movement activity of pupils, and the paper aims to determine to what extent. For model pupils, the calorie count and metabolic discharge, including sedentary analysis, were recorded through an ActiGraph accelerometer during 4-hour lessons of different types of education days. The result is that outdoor education can serve as an appropriate complement to learning that contributes to the development of pupils’ knowledge and skills while working in a real environment but also acts as a mean of increasing the possibilities for movement for pupils during their schooling.
