This paper discusses the importance of making microbes visible and tangible for children through educational field trips and hands-on activities. While microbes are invisible to the naked eye, they have enormous impacts on our daily lives – from the food we eat to our health and the environment. The authors provide comprehensive guidance for organizing class excursions to help children discover and appreciate the microbial world around them. Key impacts on everyday life: – Helps children understand how microbes are essential for producing many common foods like bread, cheese, and yogurt – Demonstrates the role of microbes in maintaining human and environmental health – Shows how microbes are used in important industrial processes and waste treatment – Helps develop informed citizens who can make better decisions about issues like antibiotic use and food safety – Encourages appreciation of beneficial microbes rather than just viewing them as germs that cause disease
