This resource provides an engaging introduction to the concept of microbiomes, particularly focusing on the 'Gut Garden' as a microhabitat within the human digestive system. It explains the role of various tiny organisms, such as bacteria, that inhabit this space. The document encourages learners to define what a microbiome is in their own words and to explore the building blocks of life—cells. By using a microscope, students are prompted to observe and identify cellular organisms in their Gut Garden, fostering a deeper understanding of microscopic life and its significance to human health.
