Functions: to detect and react to stimuli; to coordinate behaviour. Structure: the CNS is made up of the brain and spinal cord; receptors, different types of neurones, coordinator as brain or spinal cord, effectors, synapses. Explain the importance of being able to respond to environmental changes and coordinate behaviour. Explain how the nervous system is adapted for its functions. Describe the functions of the main structures in the nervous system. Explain the role of chemicals at synapses. Describe and use different methods to measure reaction time. Required practical Make a plan to investigate a factor on human reaction time. 1 Starter: any short clip that has a ‘surprise’. Explain how detection of stimuli protects the body from danger. Demo: response to different temperatures. Detecting different tastes on the tongue – draw results on diagram of tongue. Investigate sensitivity of different areas of the body. Measure reaction time using different methods, eg Sheep Dash Activity (see resources). Plan for Required practical. Plan and manage a variety of stimuli to illustrate body responses. Present and analyse results, such as: response to temperature. receptors. skin sensitivity. Evaluate different methods for measuring reaction time. Required practical plan a controlled investigation.
