This booklet looks at the importance of magnification to scientific study. It explains how a microscope works, how to construct a simple microtome (used to view fibres) and how each of these are used. A set of 15 experiments then leads students to explore fibres, different types of hair and a variety of other materials such as starch, soils and minerals using the microscope.
The resource also covers photomicrographs and gives additional investigations to be used as a source of ideas. These include studying the resistance of a fibre to action by chemicals, looking at the effects of mechanical damage and examining treated fibres.
