The exam focuses on scientific principles including forces, energy transfer, state changes, material properties, and environmental conservation. Topics address friction, magnetic attraction, filtration methods, plant reproduction, sound pitch variation, celestial mechanics, and physical characteristics of objects. Emphasis is placed on experimental design, data interpretation, and applying biological, physical, and chemical concepts. Key skills tested involve analyzing sound transmission, understanding gravitational effects, identifying energy sources, and classifying materials by their properties and behavior under different conditions. Keywords: forces, energy transfer, filtration, reproduction, sound variation, celestial mechanics, friction, state changes, material classification, conservation.
