SHS3 General Science · Semester 1 Week 9: Essentials for Survival

Lesson notes

Learning Objectives

Indicator: 3.2.1.LI.2 - Explain the peripheral nervous system.

By the end of the lesson, learners can:

Define the peripheral nervous system (PNS) and distinguish it from the central nervous system (CNS) studied in Week 8.
Identify the major parts of the PNS, including cranial nerves, spinal nerves, and ganglia, using models, diagrams, and videos.
Explain the functions of the sensory (afferent) and motor (efferent) divisions of the PNS.
Describe how the PNS connects the brain and spinal cord to the rest of the body, using everyday examples such as touching a hot pot or stepping on a sharp object.
Work collaboratively in task groups to examine PNS models and pictures, and present findings on how structure relates to function.

Exemplars (from the NaCCA curriculum)

Project-based Learning: Create different task groups and provide for groups the guidelines to work on the peripheral nervous system, such as examining the structure in relation to the functions using various models, pictures, videos, etc. and write reports. In the task groups, provide support to learners to reflect and present their reports.
Teaching and Learning Resources:
- Models, Videos, books and Pictures of the central nervous system.
- Models, pictures, books, videos and the internet show the peripheral nervous system.
- Computer/internet, diagrams/video/pictures and drawing paper
Assessment (3.2.1.AS.2). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding.
