This bundle of 4 lessons covers the content of module 5.1.1 of the OCR A-level Biology A specification, titled communication and homeostasis. As this module tends to be one of the first to be taught in the second year of the course, it’s extremely important that links are made to upcoming topics as well as challenging the students on their prior knowledge of modules 2 - 4. This is achieved through a wide range of tasks, that include exam-style questions, differentiated tasks and guided discussion periods. Quick quiz competitions are also used to introduce key terms and values in a fun and memorable way.

The following specification points are covered by the 4 lesson PowerPoints and accompanying resources included in this bundle:

  • The communication between cells by cell signalling
  • The principles of homeostasis
  • The differences between negative and positive feedback
  • The physiological and behavioural responses involved in temperature control in endotherms and ectotherms

As detailed above, these lessons have been specifically planned to tie in with the other parts of module 5, including neuronal communication, hormonal communication and animal and plant responses.
