This scenario concerns "Light and Colors" of the 6th grade of Primary School. Optics and in particular the analysis and composition of light and colors are modules that usually pose difficulties for students, often resulting in the creation of misconceptions, which are an obstacle in their attempt to understand scientific information. In the scenario, the students study the phenomena of light analysis and composition, discovering that white light can be analyzed into light of various colors and, conversely, the composition of light rays of different of colorcan give white light. The scenario proposes a didactic approach that combines real and virtual experimentation as well as the use of visualizations, videos, simulations and appropriate software to facilitate the interpretation of the phenomena and the generalization of knowledge. The scenario was applied during the 2022-2023 school year, to 22 6th grade students of a public primary school in Athens, with very encouraging results.
