Lesson notes

Learning Objectives

Indicator: 3.4.1.LI.4 - Describe how the nervous and hormonal systems in mammals’ function and work together with other systems to ensure healthy living.

By the end of the lesson, learners can:

State the basic structures of the nervous system (brain, spinal cord, nerves, neurons) and the hormonal system (glands and hormones) in mammals.
Distinguish between nervous and hormonal coordination in terms of speed, duration, and mode of transmission.
Explain how the nervous and hormonal systems coordinate with the respiratory, reproductive, and musculoskeletal systems using specific examples.
Describe the role of the hypothalamus and pituitary gland as the link between the nervous and hormonal systems.
Predict the consequences of failure in coordination between the nervous and hormonal systems on healthy living.

Exemplars (from the NaCCA curriculum)

Individual/Independent -Based Learning: in mixed-ability, all-inclusive group, learners research from textbooks, the internet, documentary films and other relevant sources about coordination in
mammals, noting down major aspects of the nervous and hormonal systems responsible for this process: learners support one another emotionally and psychologically to research on lessons. Talk for Learning: learners in mixed-ability groups discuss the functions and interactions of nerves and hormones in coordination: all learners have the opportunity to contribute to discussions to enrich their talking ability and boost their confidence in crowd.
Differential Task-Based Learning Approach: learners in mixed-ability, all-inclusive groups choose any of the organs of coordination and the sensory organs (e.g. the brain, nerve, ear, eye, etc.) and make diagrams and charts for exhibition and demonstration; learners build confidence in themselves by carrying out complex tasks. Learners support each other emotionally and psychologically and tolerate one another in the group.
