James Redfern, Dariel Burdass, Joanna Verran

• For many in the school science classroom, the term "microbiology" has become synonymous with "bacteriology". By overlooking other microbes, teachers may miss out on powerful practical tools. This article describes the development of an activity that uses algae and yeast to demonstrate gas cycling, and presents full instructions to enable the exercise to be delivered in a classroom.
