Learning Objectives

Indicator: 1.2.2.LI.2 - Discuss Causes of Physical Safety Risks of computer equipment.

By the end of the lesson, learners can:

identify at least four major causes of physical safety risks to computer equipment, including overheating due to poor heat dissipation.
explain how each cause leads to damage or failure of computer hardware.
analyse the factors that contribute to overheating in a computer system (for example, blocked vents, dust accumulation, fan failure, high ambient temperature, and overclocking).
work in mixed-ability groups to discuss and present the causes of physical safety risks, giving and receiving constructive feedback from peers.
evaluate which causes of physical safety risk are most likely to occur in their own school or home computing environment and justify their reasoning.
