Practising science: Reading the rocks and ecology

Have you ever wondered how scientists analyse the environment? This free course, Practising science: Reading the rocks and ecology, introduces you to the techniques used by science students at residential schools. You will learn how to determine where rocks have come from and how they were made. You will also examine the processes involved in determining the ecology of a particular area.
