Three students try out hands-on experiments with carbon dioxide in a science lab. With the help of Dr Peter Wothers at the University of Cambridge, they explore the properties of the air around us.

Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.

In this activity, students use bromothymol blue (BTB) to test gas samples for carbon dioxide. They apply the technique in an experiment to investigate sources of carbon dioxide in their immediate ...
