Active learning ideas
This topic introduces the biological foundations of behaviour, focusing on how our evolutionary past and our nervous system shape who we are. Students learn about the neuron, the basic unit of the nervous system, and how it uses electrochemical signals to communicate. This is not just a biology lesson; it is about understanding how physical structures like the synapse and neurotransmitters influence our moods, thoughts, and actions.
Activity 01
Students stand in a line to represent a neural pathway. They must pass a 'signal' (a squeeze or a ball) using specific rules that mimic the 'all-or-none' principle and synaptic gaps, demonstrating how information travels through the body.
How does evolution influence human behaviour?
Activity 02
Pairs are given a list of modern behaviours (e.g., social anxiety, craving fatty foods). They must brainstorm how these behaviours might have helped early humans survive in the wild and then share their best 'evolutionary explanation' with the class.
What is the structure of a neuron?
Activity 03
Groups are assigned a specific neurotransmitter like Dopamine or Serotonin. They create a 'profile card' detailing its function, what happens when there is too much or too little, and a real-life example of its effect on behaviour.
How do neurons communicate with each other?
A few notes on teaching this unit
Watch Out for These Misconceptions
Neurons physically touch each other to send messages.
Neurons are separated by a tiny gap called the synapse. Using a physical model where students have to 'throw' a chemical (ball) across a gap helps them understand that communication is chemical, not just electrical.
Evolution means humans are 'perfectly' designed.
Evolution is about survival in a specific environment, which can lead to 'mismatches' in the modern world (like the obesity crisis). Discussion helps students see evolution as an ongoing process of adaptation.
Methods used in this brief
Structure and Function of the Nervous System
Details the central and peripheral nervous systems, focusing on the brain and spinal cord. It explores how different brain regions control specific functions.
8 methodologies
The Endocrine System and Heredity
Explores the role of hormones secreted by the endocrine glands in regulating behaviour. It also covers the principles of heredity and genetics.
8 methodologies
Socialisation and Acculturation
Analyzes the cultural basis of behaviour, focusing on the processes of socialisation and acculturation. Students learn how society and culture shape individual identity.
