Why do we draw?

Observe and study

A true-to-nature and schematic drawing

Write down 2 differences between the pictures of the apple

A true-to-nature and schematic drawing

• Emphasis on how something really looks
  
• As realistic as possible
  
• With color or shades of gray
  
• With lots of detail
  

• Emphasis on important features
• Only important lines
• No color
• No details (such as dots or spots)

Biological drawing rules

• Draw with pencil
• Draw large (use the entire drawing surface)
• Do not draw sketchily
• Draw only what you can see (don't make anything up)
• Draw in a drawing frame
• Name the parts to the right of the drawing
• Indicator lines may not cross
• Note at the top of the drawing:

      - What you have drawn
      - What kind of biological drawing it is
      - Your used magnification, if necessary

• Note your name, class and date at the top right

What is it?

How to start a drawing
