This concise lesson has been written to cover specification point 5.1.1 (d) of the OCR A-level Biology A specification which states that students should be able to apply an understanding of the behavioural responses in temperature control in ectotherms. The main aim when designing the lesson was to support students in making sensible and accurate decisions when challenged to explain why these types of organisms have chosen to carry out a particular response. A wide range of animals are used so students are engaged in the content matter and are prepared for the unfamiliar situations that they will encounter in the final exam. Time is also taken to compare ectotherms against endotherms so that students can recognise the advantages and disadvantages of ectothermy.
This lesson has been written for A-level students studying on the OCR A-level Biology A course. Lessons on temperature control in endotherms and the principles of homeostasis and cell signalling, which are also in module 5.1.1, are also available so please download those too as they will allow students to make connections between one lesson, the previous and the next.

Homeostasis, Excretion, Neuronal and Hormonal communication (OCR A-level Biology A)
This bundle of 20 lessons covers the majority of the content that's included in modules 5.1.1 - 5.1.4 of the OCR A-level Biology A specification. All of the lessons are highly detailed and have been planned at length to ensure that they are filled with a wide range of tasks to engage and motivate the students whilst checking on their understanding. The following specification points are covered by the lessons in this bundle: 5.1.1: Communication and homeostasis * The communication between cells by cell signalling * The principle of homeostasis * The physiological and behavioural responses involved in temperature control in endotherms and ectotherms 5.1.2: Excretion as an example of homeostatic control * The functions of the mammalian liver * The gross structure and histology of the kidney * The processes of ultrafiltration and selective reabsorption * The control of the water potential of the blood * The effects of kidney failure and its potential treatments 5.1.3: Neuronal communication * The roles of mammalian sensory receptors in converting stimuli into nerve impulses * The structure and functions of sensory, relay and motor neurones * The generation and transmission of nerve impulses in mammals * The structures and roles of synapses in transmission 5.1.4: Hormonal communication * Endocrine communication by hormones * The structure and functions of the adrenal glands * The structure of the pancreas * The regulation of blood glucose concentration * The difference between diabetes mellitus type I and II * The potential treatments for diabetes mellitus It is estimated that it will take in excess of 2 months of allocated A-level teaching time to cover the detail included in these lessons If you would like to sample the quality of the lessons in this bundle, then download the following lessons as they have been shared for free: * The principles of homeostasis * Temperature control in ectotherms * The functions of the liver * The structure of the kidney * The generation and transmission of nerve impulses * Endocrine communication

Module 5.1.1: Communication and homeostasis (OCR A-level Biology A)
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. If you would like to sample the quality of the lessons in this bundle, then download the principles of homeostasis and temperature control in ectotherms lessons as these have been uploaded for free
