This series provides an in-depth exploration of the microscopic life that surrounds and inhabits our environment, from weevils in the carpet to moulds that rot our food. The books cover the variety of micro-organisms, their survival, reproduction, and the impact they have on their environments. Key topics include the micro-organisms in our homes and gardens, their role in hygiene and natural processes, and their practical uses in products like washing powder. The series aligns with the KS2 Science Curriculum, offering experiment suggestions for children aged 9-12 to further understand the microscopic world.
