To begin with, students investigate the potential of their personal devices as a means to perform spectrophotometric chemical analysis. Utilizing smartphone spectroscopy, in conjunction with free exercises. This approach offers an alternative to costly and less accessible instruments for particle size and colorimetry assays. We developed an alternative hands-on laboratory activity to promote the use of electronic devices, such as smartphones and laptops, in photographic image analysis using open-source computer programs. A simple image analysis was conducted using ImageJ from the National Institutes 80 of Health (NIH). This analysis involved determining the unknown concentration of a solution from a calibration curve and measuring particle sizes from images of fish scales. This activity also aims to introduce Jamovi software to the chemistry field. Jamovi is freeware with a graphical user interface (GUI) written in the R language. The discussion began with hypothesis testing by the students using the Mann-Whitney U Test in Jamovi. Considering the experiment's (i) cost-effectiveness, (ii) minimal setup 85 requirements, and (iii) exploration of hypothesis testing, it is suitable for students in general chemistry courses at both high school and introductory college levels.
