Mechanical energy conversions, steam turbine dynamics, and liquid hydraulic pressure systems form the curriculum for Grade 8 Integrated Science during Term 3, encompassing 29 laboratory lessons across 8 pages. Experimental procedures correspond to Active Integrated Science Grade 8 pages 106 to 131.
Learners investigate physical science concepts and engineering mechanisms through hands-on laboratory setups grouped into four key study topics:
- Energy Transformations in Nature: tracing potential and kinetic energy shifts in swinging pendulums, modelling mechanical work, and identifying environmental energy transfers in week 1.
- Steam-Driven Turbines: assembling small-scale steam turbine models, demonstrating thermal-to-kinetic energy conversion, and examining industrial turbine power generation in weeks 1 and 2.
- Energy Appliance Safety: reviewing operational safety precautions for household electrical and mechanical appliances, preventing thermal shocks, and managing machinery in week 2.
- Liquid Pressure and Hydraulics: investigating Pascal’s principle in liquids, labelling master and slave cylinders in vehicular hydraulic brakes, and solving pressure problems across weeks 6 and 7.
