A-level Biology: Practical and Experimental Design - Top Tips and Question Pack

Top Tips !

  • Never write "amount" you mean mass, volume or concentration. 
  • Refer to "a control experiment" or "a variable that I will control (and then name the value and method of control)" but never to "a control variable"
  • Independent variable is what you change.
  • Dependent variable is what you actually measure in the experiment (not rate).
  • Organisms vary from each other unless they are clones !
  • When you suggest improvements think about improving the method rather than the equipment (e.g. control a variable that wasn't previously)
