SHS General Science practice questions
379 questions across 17 topics of the new NaCCA curriculum, each with a written explanation.
General Science draws physics, chemistry and biology into one subject, usually taught through things you can see working. Year 1 covers the characteristics of science, forces, materials, diffusion and osmosis, reproduction, health and safety, and practical ground like solar panels, basic electronics and local industry. Year 2 continues with electricity, buoyancy, gaseous exchange, the human excretory organs, the nature of liquids, pathogenic diseases and indigenous beverages.
