1.6 The formation of metamorphic rocks
Have you ever wondered how scientists analyse the environment? This unit 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.

1.1 Note taking in this context

Although the audio file included in this unit was designed to compliment the D218 Social Policy: Welfare, Power and Diversity Open University course its contents are still relevant to anyone wishing to improve their understanding of note taking. The audio file, however, uses specific examples associated with the Social Sciences.

The audio file was recorded in 1998. John Clarke discusses the value and best ways of note taking with OU colleagues Esther Saraga and Gerry Mooney.

Introduction

This unit focuses on the creation of a semiconductor transistor – a versatile tiny transistor that is now at the heart of the electronics industry. In the video clips, the history of the incredible shrinking chip, its Scottish connections and an explanation of the physics that make chips work are accompanied by a reconstruction of making a transistor using the crude techniques of yesteryear.
