Geographic studies that examine the phenomenon of the geosphere provides opportunities for learning in the field. Geography has provided material objects to undergo natural geomorphic processes. Weathering is one of the geomorphic processes caused by the climate. Climate engenders weathering processes, dissolution, and the removal of material in vertical and horizontal effects on soil properties. Students are directed by research procedures based on the hypothesis that has been formulated to establish scientific thinking skills. This research method uses action research by the Kolb cycle through steps, concrete experience, reflective observation, abstract conceptualization, and active experimentation. The number of students is as many as 40. Student activity starts from the engagement proposal, hypothesis formulation, data collection, discussion, and reporting. Acquisition of scientific thinking skills are exhibited using a test. Results can be described at every step with an analysis using paired t-test between pre-test and post-test. The concrete experience involves students making the determination of point coordinates on a map where Vertisol soil types are identified in the field using GPS. Observation of soil properties as climate effects are confirmed with the hypothesis. Students reflect on the observations and find arguments based on previous knowledge. In relation to abstract conceptualization, students discuss findings supported by literature and journals. Active experimentation involves the scientific thinking skills of students in experimentation experiences regarding the new phenomenon of climate effect on the soil properties. Analysis using paired t-test between pre-test and post-test showed significance at the level of 0.00. Scientific thinking skills can be established by the research-based outdoor study. This means that scientific thinking skills can be improved through a research-based outdoor study in climosequent. © 2020, Primrose Hall Publishing Group.
