SHS1 Applied Technology · Semester 1 Week 6: Introduction to Vehicle Technology

Lesson notes

Learning Objectives

Indicator: 1.1.2.LI.3 - Differentiate between mechanical, hydraulic and pneumatic braking systems

By the end of the lesson, learners can:

Describe how each of the three braking systems (mechanical, hydraulic, and pneumatic) transmits force from the driver to the brake shoes or pads.
Compare the three systems in terms of force multiplication, response time, application area, and components used.
Classify given braking system scenarios or diagrams as mechanical, hydraulic, or pneumatic with clear justification.
Evaluate the advantages and limitations of each braking system and recommend the most suitable system for different types of vehicles commonly found in Ghana.
Work collaboratively in mixed-ability groups to demonstrate and explain how a moving vehicle stops, respecting diverse viewpoints and contributions.

This lesson builds directly on Week 4 (transmission system components) and Week 5 (braking system components and functions). Learners already know the parts of a braking system; this week focuses on how those parts are actuated and how the systems differ.

Content standard: 1.1.2.CS.1 - 1.1.2.CS.1 Demonstrate knowledge and understanding of vehicle technology subsystems 1.1.2.LO.1 Detect problems in the vehicle transmission and braking system
Indicator: 1.1.2.LI.3 - Differentiate between mechanical, hydraulic and pneumatic braking systems
Suggested placement: Semester 1, Week 6 (Week 6 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.
Curriculum reference: NaCCA curriculum document, p. 31

Exemplars (from the NaCCA curriculum)

Group work/collaborative learning: Learner's brainstorm and tolerate the with views of others to share ideas on how a moving vehicle stops or slows down and the principles behind it.
Talk for learning approaches: Assist learners to make appropriate references to models for actuating the brakes effectively. Show videos on the three ways (mechanical, hydraulic and pneumatic) of operating the vehicle brakes and learners discuss among the mixed ability groups how it works.

Assessment (1.1.2.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.
