This thesis presents a research project in Chemistry carried out in a first-grade primary school class, aimed at promoting the knowledge of materials, environmental awareness and the importance of recycling. The research stems from the need to integrate an active and multidisciplinary pedagogical approach into teaching practices, capable of engaging young learners through practical and tangible experiences, thereby facilitating learning and awareness of environmental issues. The project introduced the core concepts of materials, recycling, pollution, and biodegradability. Building on children's everyday experiences, the characteristics and properties of different materials were analysed. Integrating prior knowledge of waste sorting, the recycling process was then explored, with a particular focus on plastics. The environmental consequences of inappropriate waste disposal were observed through videos and pictures. Bioplastics were then introduced as a sustainable alternative, a topic of current relevance in addressing environmental challenges. The laboratory activity involving the production of galalith allowed students to engage directly with the materials and the scientific concepts discussed, while observing the decomposition process of materials made the concept of biodegradability tangible. The results achieved were positive and meaningful with students demonstrating a clear understanding of the differences between materials and an increased awareness of waste sorting, leading more responsible behaviours. This project contributed to the development of scientific skills and environmental awareness, promoting a practical and engaging approach to sustainable chemistry and environmental protection.
L’elaborato di tesi presenta un percorso di Chimica realizzato in una classe prima della scuola primaria, finalizzato a promuovere la conoscenza dei materiali, la consapevolezza ambientale e l’importanza del riciclo. La ricerca nasce dalla necessità di integrare, nelle pratiche didattiche, un approccio attivo e multidisciplinare, capace di coinvolgere i bambini attraverso esperienze pratiche e concrete, facilitando così l’apprendimento e la sensibilizzazione alle tematiche ambientali. Il progetto ha introdotto ai concetti di materiali, riciclo, inquinamento e biodegradabilità. Partendo dall'esperienza quotidiana dei bambini, si sono analizzati i materiali e le loro caratteristiche. Integrando le preconoscenze riguardo la raccolta differenziata, si è poi approfondito il viaggio del riciclo, con particolare attenzione alla plastica, osservando tramite video e immagini le conseguenze ambientali dello smaltimento improprio dei rifiuti. Successivamente è stato introdotto il tema della bioplastica, come alternativa sostenibile, un argomento di grande attualità e rilevanza nel contesto delle sfide ambientali odierne. L’attività laboratoriale di produzione della galalite ha permesso agli alunni di toccare con mano gli argomenti trattati e sperimentare in prima persona un processo di creazione eco-compatibile, mentre l’osservazione del processo di decomposizione dei materiali ha reso tangibile il concetto di biodegradabilità. I risultati conseguiti sono stati positivi e significativi: gli studenti hanno dimostrato maggiore comprensione delle differenze tra i materiali e una maggiore attenzione alla gestione dei rifiuti, adottando comportamenti più responsabili. Questa esperienza ha favorito lo sviluppo di competenze scientifiche e di sensibilità ambientale, promuovendo un approccio pratico e coinvolgente alla chimica sostenibile e alla tutela dell'ambiente.

This thesis presents a research project in Chemistry carried out in a first-grade primary school class, aimed at promoting the knowledge of materials, environmental awareness and the importance of recycling. The research stems from the need to integrate an active and multidisciplinary pedagogical approach into teaching practices, capable of engaging young learners through practical and tangible experiences, thereby facilitating learning and awareness of environmental issues. The project introduced the core concepts of materials, recycling, pollution, and biodegradability. Building on children's everyday experiences, the characteristics and properties of different materials were analysed. Integrating prior knowledge of waste sorting, the recycling process was then explored, with a particular focus on plastics. The environmental consequences of inappropriate waste disposal were observed through videos and pictures. Bioplastics were then introduced as a sustainable alternative, a topic of current relevance in addressing environmental challenges.
