Study Notes
Scientific Drawing Guidelines
- Scientific drawings should be as simple as possible while still being true to life.
- Drawings must be done in pencil, with no colored pens or markers allowed.
- Essential materials needed include sharp pencils, a ruler, and a sharpener.
- Different pencil techniques are used to illustrate various natural objects.
Drawing Techniques
- Smooth-edged specimens (e.g., leaves) should be drawn using smooth, unbroken lines.
- Specimens with fuzzy edges (e.g., wool, cotton, or hair) should be drawn with fuzzy lines.
- Broken lines should be used to indicate the shape of underlying structures.
Shading Alternatives
- No shading is done in scientific drawings.
- Alternative techniques are used instead:
- Stippling (dotting)
- Streaking (lines in one direction)
- Cross-hatching (lines crossing each other)
Using Symbols
- Symbols can be used in scientific drawings if their meaning is clearly explained.
