Environmental awareness is a crucial aspect of education across all levels, particularly in primary education. Teachers play a vital role in promoting this awareness through innovative teaching methods. However, many approaches lack cross-curricular integration, particularly with art education, which can enhance creative and critical thinking about environmental issues. Traditional teaching methods often fall short of promoting scientific reasoning, leading to the need for more engaging educational strategies. Research indicates that hands-on experiential learning significantly boosts students’ interest in science and environmental education. These new methods must align with students’ cognitive abilities. Even young students can engage in discussions and listen actively, making them capable of exploring environmental topics. This chapter aimed to assess fourth-grade students’ attitudes toward the environment and art, as well as their ability to connect the two. We sought to determine how well students could identify environmental themes in both famous artworks and their own creations. Based on their responses, we developed an interdisciplinary didactic approach to teaching environmental content through visual arts (ECTA). This approach was implemented in an experimental group, and the results were analyzed. Findings showed that integrating environmental themes with art education positively influenced students’ environmental awareness and attitudes. Students in the experimental group demonstrated significant improvements in their knowledge of environmental and artistic concepts, which was reflected in their artwork. They exhibited a heightened sensitivity to environmental issues, effectively portraying these themes in their creations. Additionally, they learned about recycling and the properties of waste materials through artistic activities. Overall, the ECTA approach not only enhanced students’ understanding of environmental issues but also developed a sense of responsibility toward the environment, highlighting the importance of linking environmental education with creative expression. The chapter presents a part of the ECTA teaching approach with an emphasis on some teaching units.
