Study Notes
Making Scientific Drawings
- Scientific drawings should be as simple as possible.
- Pencil is the preferred medium, and coloured pencils can be used.
- A ruler, eraser, and sharpener are necessary tools.
- Different pencil techniques are used to draw various objects:
Natural Objects
- Smooth-edged specimens are drawn using smooth, unbroken lines.
- Fuzzy-edged specimens (e.g. wool, cotton, or hair) are drawn using underlying structures with broken lines.
- No shading is used in scientific drawings.
Other Techniques
- Stippling (dotting) is used to create an effect.
- Streaking (lines in one direction) is used to create a pattern.
- Cross-hatching (lines crossing each other) is used to create depth and texture.
Symbols in Drawings
- Symbols can be used in scientific drawings if their meaning is clearly explained.
Examples of Drawing Techniques
- FIG 1.12 illustrates various drawing techniques used in science.
