Core Concepts for Early Childhood Microbiology Education.

This article explores how microbiology can be meaningfully integrated into science education for preschoolers, children under 6 years old. Current research shows that the early years represent a critical period for scientific learning. Microbiology offers a unique opportunity to engage children in curiosity, and reflection by connecting the invisible microbial world with their everyday experiences. Its introduction at a young age supports the development of scientific thinking skills and helps correct prevalent misconceptions about microorganisms that often continue into adulthood. To overcome these misunderstandings, we designed and implemented a programme for early childhood to learn fundamental microbiological concepts within the framework of a science communication initiative called Ciencia Maravilla. This programme, created by teachers and researchers from the National University of Rosario, combines play, storytelling, and experimentation to encourage curiosity, critical thinking, and early scientific literacy. We propose to teach the microscopic nature of microorganisms, their vast diversity, their ubiquitous presence across all environments, and their essential functions as living organisms. Furthermore, we invite the educational community to critically examine anthropocentric perspectives that primarily associate microorganisms with human health, disease, and benefits. Instead, we advocate for a broader ecological approach, anchored in pedagogical practices that promote deep learning, reflection, and authentic inquiry experiences, which is crucial for fostering a balanced and nuanced understanding of the microbial world through science education.
