The objective of the present study was to investigate the contributions of the development of laboratory experiments on soils in the Geography discipline. The subjects of the research were 40 students of the 1st year of the Technical Courses of Integrated Middle Level in Chemistry and Mechanics, belonging to the IFAM-CMC. The research is qualitative and was developed from the performance of interventional activities characterized by dialogic expository classes and laboratory experiments. The data collection instruments used were questionnaires, guiding scripts and evaluations carried out in each activity. The laboratory experiments were satisfactory, as the students were able to recognize minerals and rocks; identified the youngest horizon (O) and the oldest horizon (R) of the soil; differentiated the granulometric fractions by size and soil texture; understood the colors of soils, as well as the ability to infiltrate and retain water in soils with different characteristics. Experiments in the investigative and interdisciplinary laboratory were essential for the understanding of the themes studied, being important to carry out in technical education, strengthening an integrated, regional and reflective learning
