1 Rules of Scientific Diagrams
How to Draw Microscopic Images

2 Rules of Scientific Diagrams
Each diagram MUST include: Title Magnification Date Detail Labels Each diagram MUST: Be drawn on a blank paper Be drawn in pencil Be at least 10 cm in diameter Be professional (e.g. lines drawn with rulers)

3 Why am I SO picky????!

4 What is this??? putting green? donut? cell? key? landscape?
bottle opener? egg?

5 IMPORTANT NOTE Diagrams must be very descriptive and require many components in order to be properly understood

6 Diagram Components Title Magnification Date Labels Detail

7 Diagrams need a….. title The title needs to tell the viewer what the diagram is supposed to be representing

8 Diagrams need a….. magnification
The magnification tells the viewer how many times the object has been “blown up” in size Will be either 40x, 100x, or 400x in this unit

9 Diagrams need a….. date The date tells the viewer what day the diagram was drawn on

10 Diagrams need….. labels The diagram requires labels to tell the viewer what each part of the diagram is

11 Diagrams need.…. detail The diagram needs to be detailed enough to show contours and textures between different parts Do NOT use colour (pencil crayons) when drawing biological drawings

12 Professional Guidelines
Blank paper Drawn in pencil Neat and professional Use Petri Dish or compasses to draw your field of view I WILL NOT ACCEPT ANY DIAGRAM THAT DOES NOT FOLLOW THE PROFESSIONAL GUIDELINES

15 How would you draw the following image?
These are human red blood cells that were viewed at a magnification of one thousand from their actual size. They were observed on November 17, 2014.

16 Assignment Use a microscope to locate a few cells of the Elodea leaf (prepared slide) Using the guidelines for drawing scientific diagrams, make a diagram of what you see in the microscope Label the following: Cell wall (the outer part of the cell) Chloroplasts (the little green things in the cell) Cytoplasm (the blank space in the cell) DUE:
