The exam assesses key scientific principles in biology, chemistry, and physics. Topics include cell structures, photosynthesis, the rock cycle, and the human circulatory system. Investigations explore air resistance, displacement reactions, and sound wave properties. Practical skills are tested through activities like balancing moments, interpreting distance-time graphs, and calculating reactivity series. Concepts such as planetary motion, energy transformations, and light intensity in photosynthesis are also covered.
