This study employed a case study methodology to investigate students' misconceptions about solid, liquid, and atmospheric pressure. The research included 36 8th-grade students from various middle schools in Giresun, comprising 19 girls and 17 boys. Data collection involved a test consisting of 14 concept cartoon questions, and the concept cartoons themselves were created using the Storyboard That program. These concept cartoons covered solid, liquid and atmospheric pressure. The study revealed that students held a variety of misconceptions related to solid, liquid, and atmospheric pressures. Notably, the students exhibited low levels of understanding when it came to the relationship between liquid pressure and Pascal's Principle, as well as the factors influencing atmospheric pressure. Concept cartoons emerged as effective tools for identifying and diagnosing these misconceptions among students. In summary, this research aimed to uncover misconceptions regarding pressure among 8th-grade students. It underscored the significance of concept cartoons in pinpointing areas where students required additional clarification and education to rectify these misconceptions.
