IB Biology SL‎ > ‎

00 Our Units

Each unit of study is connected through one key concept and one or more of the fundamental related concepts of Biology: 
  • Structure & Function
  • Universality & Diversity
  • Evolution
  • Equilibrium within Systems



Each unit is finished with a test, modeled on authentic Paper 1 & 2 examination questions: 
  • 30 points of multiple-choice
  • 30 points of data analysis and structured factual recall
  • 20 points of extended response (selected from a range of choices)
As the course progresses, these unit tests become cumulative, incorporating natural connections with topics previously studied. 

Weekly Extended Response

Each week you will be given an 8-mark question based on content from the previous two weeks. 
This assesses objective 2 and 3 knowledge (most of the lower-order content is practiced through Quia quizzes, in-class tasks, notes). 


Units will typically contain one or more labs requiring a lab report. All are graded, though in the early stages of the course these might not be suitable for inclusion in the final portfolio for IA submission to the IB moderators. Feedback and grading is completed via Turnitin. 


Each month, you will also be graded on the GoogleSites rubric, based on content development and reflection on your progress, as well as completion of Quia Quizzes and class tasks.
