Lesson 7 - Lab 2 - Observations and Drawings of Human Cells
Student Performance Objectives
1. Draw representative cells of the human body in the scientific format: 3H pencil,
unlined,
white paper, proper heading for each sketch, indication of magnification, use
of ruler to
draw labelling lines, and neat labelling.
Lesson Outline
A. Protocol for drawings: emphasis on neatness and clarity
1. Use of 3H (non-smudging) pencil
2. Unlined (typing) paper utilized for drawings
3. Proper heading: name, class, instructor, and date.
4. Titling of each drawing based on a prepared slide's label
5. Indication of total magnification used to make the drawing
6. Use of ruler to draw lines from labels to item being labeled
7. Use of neatly printed lettering for labels
8. Proper placement of labels on one or both sides of the illustration
B. Students draw representative fields from the following prepared slides, to be handed
in for
grading.
