SHS3 General Science · Semester 1 Week 10: Essentials for Survival

Lesson notes

Learning Objectives

Indicator: 3.2.1.LI.3 - Describe autonomic nervous system.

By the end of the lesson, learners can:

Define the autonomic nervous system (ANS) and distinguish it from the somatic (voluntary) nervous system.
Identify the two main divisions of the ANS, the sympathetic and parasympathetic systems, and state the general role of each.
Describe the effect of sympathetic and parasympathetic stimulation on at least four organs (heart, lungs, pupils, digestive system).
Explain how the ANS maintains internal balance (homeostasis) using a daily life example such as rest versus a sudden fright.
Work collaboratively in groups to match ANS functions to their correct division and justify their choices.

Group work/collaborative Learning: In their differentiated learning groups, learners match the structure of neurons to their functions. Support groups to exchange and discuss their matchings and describe the structure and functions of the neuron.
