This thesis investigates the potential of the scientific method as an educational tool for introducing chemistry concepts in primary school. The main goal was to make complex scientific concepts related to chemical reactions understandable and accessible by stimulating direct observation, hypothesis formulation and shared knowledge construction. After an initial introductory phase dedicated to the presentation of the scientific method and its phases, students participated in a series of experiments inspired by simple cooking recipes, through which they explored chemical phenomena such as leavening, pH, and emulsion. Laboratory experiences were designed to be engaging and connected to the children’s everyday lives. To promote a collaborative learning environment, the students were organized into small groups and carried out the activities as scientists. They followed operational instructions, observed the phenomena and completed laboratory worksheets. Each session ended with a group discussion aimed at formulating basic scientific theories. The active and cooperative approach proved to be an effective strategy to stimulate curiosity, scientific thinking, and motivation to learn. The research results show that primary school children are able understand and learn complex scientific concepts when approached through practical, engaging and meaningful activities.
Questa tesi indaga il potenziale del metodo scientifico come strumento didattico per affrontare concetti di chimica nella scuola primaria. L'obiettivo principale è stato quello di rendere comprensibili e accessibili concetti scientifici complessi, legati alle reazioni chimiche, stimolando l’osservazione diretta, la formulazione di ipotesi e la costruzione condivisa del sapere. Dopo una prima fase introduttiva dedicata alla presentazione del metodo scientifico e delle sue fasi, sono stati proposti alcuni esperimenti ispirati a semplici ricette di cucina, attraverso i quali gli alunni hanno potuto scoprire fenomeni come la lievitazione, il pH e l’emulsione. Sono state proposte esperienze laboratoriali coinvolgenti, connesse al vissuto quotidiano dei bambini. Per favorire un ambiente didattico collaborativo gli alunni sono stati organizzati in piccoli gruppi e hanno svolto le attività in veste di scienziati, con lo scopo di sperimentare le reazioni chimiche seguendo indicazioni operative, osservando i fenomeni e redigendo schede di laboratorio. Ogni incontro si è concluso con una rielaborazione delle osservazioni finalizzata alla formulazione di semplici teorie scientifiche. L’approccio attivo e collaborativo si è rivelato uno strumento efficace per stimolare la curiosità, il pensiero scientifico e la motivazione all’apprendimento. I risultati della ricerca dimostrano che i bambini della scuola primaria possono comprendere e imparare concetti scientifici complessi se affrontati mediante attività pratiche, coinvolgenti e significative.

Abstract
This thesis investigates the potential of the scientific method as an educational tool for introducing chemistry concepts in primary school. The main goal was to make complex scientific concepts related to chemical reactions understandable and accessible by stimulating direct observation, hypothesis formulation and shared knowledge construction. After an initial introductory phase dedicated to the presentation of the scientific method and its phases, students participated in a series of experiments inspired by simple cooking recipes, through which they explored chemical phenomena such as leavening, pH, and emulsion. Laboratory experiences were designed to be engaging and connected to the children’s everyday lives. To promote a collaborative learning environment, the students were organized into small groups and carried out the activities as scientists. They followed operational instructions, observed the phenomena and completed laboratory worksheets. Each session ended with a group discussion aimed at formulating basic scientific theories. The active and cooperative approach proved to be an effective strategy to stimulate curiosity, scientific thinking, and motivation to learn. The research results show that primary school children are able understand and learn complex scientific concepts when approached through practical, engaging and meaningful activities.| File | Dimensione | Formato | |
