Spectrometry; project-based learning; STEM educationAbstract
This paper introduces students to quantitative spectrometry using a hands-on approach, building a simple, low-cost spectrometer to characterize discrete or continuous light spectra, using a smartphone or laptop camera. This project-based learning activity is performed without any specialized equipment (favoring inclusive education at high school and university levels) and allows students to develop scientific skills through the measurement and characterization of light sources, reinforces technological and engineering skills through the construction of the optical instrument and the analysis of light spectra through free software, and applies mathematical competences through the statistical analysis of data. The project is an inclusive and integrative STEM activity, building contextualized and quantitative knowledge in these areas.
