Along these lines, this research describes a STEM activity developed to\u00a0promote the teaching of chemistry content related to the solubility of potassium nitrate in water. It also facilitated the mastery of technological skills such as programming Arduino microcontrollers and using Microsoft Excel as\u00a0tools for automatic data acquisition and analysis. Eighty pre-university Chemistry students participated in this\u00a0research. This pedagogical approach was divided into three main stages: (1) preliminary research on components used in the experimental apparatus; (2) introduction to the assembly of electrical circuits and Arduino programming; (3) experimental investigation of the dependence of potassium nitrate solubility on temperature. The activity allowed the students to successfully achieve the proposed chemistry learning objectives while mobilizing other scientific and technological knowledge and skills. Despite the students\u2019 limited prior knowledge of programming and electronics, as well as their limited proficiency in data analysis software, the\u00a0integration of\u00a0programming in the Chemistry class proved to be a differentiating factor with a highly positive\u00a0impact, particularly in terms of motivation and interest among most students.<\/jats:p>","DOI":"10.1515\/cti-2024-0004","type":"journal-article","created":{"date-parts":[[2024,7,1]],"date-time":"2024-07-01T07:40:40Z","timestamp":1719819640000},"page":"217-229","source":"Crossref","is-referenced-by-count":7,"title":["Investigating the influence of temperature on salt solubility in water: a STEM approach with pre-university chemistry students"],"prefix":"10.1515","volume":"6","author":[{"given":"Jos\u00e9 L.","family":"Ara\u00fajo","sequence":"first","affiliation":[{"name":"CIDTFF, Department of Education and Psychology , 56062 University of Aveiro , Campus Universit\u00e1rio de Santiago , Aveiro , 3810-193 , Portugal"}]},{"given":"Carla","family":"Morais","sequence":"additional","affiliation":[{"name":"CIQUP, IMS, Department of Chemistry and Biochemistry, Faculty of Sciences, University of Porto , Rua do Campo Alegre , Porto , 4099-002 , Portugal"}]}],"member":"374","published-online":{"date-parts":[[2024,7,2]]},"reference":[{"key":"2024092607282193718_j_cti-2024-0004_ref_001","doi-asserted-by":"crossref","unstructured":"Akrami, Z.
