In this activity, students observe billions of soil microbes and ‘see’ microbes at work as they soft boil an egg in a compost bin.
By the end of this activity, students should be able to:
- discuss that soil is home to living things, including things we cannot see
- associate the heat generated by microbial activity with the heating of an egg in a compost bin.

Nature of science
Science is part of our daily lives. Scientific investigations can be as simple as placing an egg in a compost bin and observing what happens next.
Soil microbes are essential in the composting process. Find out more about backyard composting on this website.
