Science Ideas and Concepts
Scientific study requires a basic knowledge and understanding of ideas and concepts. This collection explains the ideas that are fundamental to Exploring with Microscopes.
Magnification and resolution – Information Sheet
Microscopes enhance our sense of sight. They make things appear bigger (magnify them) and increase the level of detail we can see (resolution).
How microscopes magnify – Information Sheet
A microscope uses a lens or lenses to make small objects look bigger and to show more detail. Over time, technological innovations have made microscopes easier to use and led to increased image quality.
The microscopic scale – Information Sheet
The microscopic scale is the range of sizes that can be detected using microscopes. It spans seven orders of magnitude (from a millimetre to one ten-millionth of a millimetre).
Animal cells and their shapes – Information Sheet
Animal cells come in all kinds of shapes and sizes. We can learn a lot about what a cell does by looking at its shape.
Cell organelles – Information Sheet
Organelles are structures that have specific functions in the cell. They have only been studied in detail since the invention of the transmission electron microscope.
