1. Draw what you see, not what you think should be there. 2. Use pencil for diagrams, labels and titles. 3. Use clean-cut lines for diagrams (do not sketch). All drawings are to be done on unlined paper, with one drawing per sheet of 81/2 X 11 paper. 4. Drawing should be large enough to show all parts without crowding. You have a whole sheet of paper, don’t be afraid to use it. When doing detailed diagrams of cells and their contents, the cells should measure at least 5cm in length. 5. Keep your drawings to the left of the page. Put all the labels to the right of the diagram. All labels should be printed. Use a ruler for label lines and make sure you do not cross your label lines. 6. Do not shade your drawing. If you wish to indicate a darker area, use dots. Indicate the thickness of a plant cell wall by using two lines.
7. When one representative cell of a tissue is to be drawn, make sure you include the cell boundaries of the other cells that border it. 8. Include a printed and underlined title immediately above the drawing in the centre of the page. The scaled/drawing magnification follows the title in parentheses [e.g. BONE CELL (300X)] Following this, include the total magnification – “as viewed under 40X” 9. Following the title, indicate whether the slide is wet mount, dry mount, or a prepared slide. Also indicate whether any stain was used in the preparation of the slide. This will be indicated on the slide if it is prepared. 10. 1 cm = 10,000 μm *Remember this!!!* 11. Include your name and the date in the top right hand corner. 12. Move the slide around to get a good overview of the specimen, don’t just concentrate on one part. Also view the slide under different magnifications and light amounts.
MagnificationField of View (µm) Low (40x)4500 Medium (100x)1800 High (400x) 450 Finding the estimated size of the cell Estimated Size = Field of View Fit number Fit number = how many times that cell/specimen fits across the field of view Finding the scaled magnification Scaled magnification = Diagram Size Estimated size Scaled magnification can also be called drawing magnification. All your units need to be in micrometers, shown as µm You need to show the formulas and your work on the bottom of your drawing. The estimated size goes along the left margin, and the scaled magnification/drawing magnification goes in your title.

Your homework assignment (the characteristics of life) was due by the end of the school day yesterday. The alternate due date is TODAY by the end of the school day. If it is not submitted by then, you will lose points. These marks will go into PowerSchool on Monday. Your group members and virus selection for your project was due yesterday. The alternate due date, as mentioned in class, is TODAY by the end of the school day. If this is not submitted by then, you will begin to lose points. I will have groups and selections for you on Monday – if there is any issues with group numbers, I will discuss that with you on Monday as well. We will be in the LAB (209) on Monday. You will submit one biological drawing by the end of the class for me to mark, as well as your homework assignment, which includes a biological drawing.
