Observing soil microbes

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.
