GCE A/L Science for Technology study guide
GCE A/L Science for Technology · Work through your exam, one topic at a time.
Science for Technology is an Advanced Level subject in Sri Lanka's GCE A/L Technology stream, taken alongside Engineering Technology and Bio-systems Technology by students aiming at engineering, technology, and applied-science degree programmes and higher national diploma courses. It is designed as a bridging subject: it assumes Ordinary Level science and mathematics, then builds the physics, chemistry, biology, and instrumentation background that technology-stream students need before university coursework. The GCE A/L Science for Technology study guide has 10 sections and about 2,927 words.
01Measurement, Units and the Scientific Method
Measurement, units and the scientific method is examined through practical-style calculations rather than recall: you must choose an instrument, record a value with its uncertainty, and justify a conclusion from data. Expect SI units, prefixes, dimensional consistency, significant figures and graph work.
357 words, about 2 min02Mechanics and Properties of Matter
Mechanics and properties of matter tests motion, forces, energy and the behaviour of materials under load. Numerical problems dominate, often combining Newton's laws with stress and strain.
331 words, about 2 min03Thermal Physics and Energy Transfer
Thermal physics and energy transfer covers temperature measurement, heat quantities, the gas laws and the first law of thermodynamics. Questions often require careful sign handling and unit conversion.
298 words, about 1 min04Waves, Optics and Sound
Waves, optics and sound tests wave behaviour, ray diagrams and resonance. Expect calculations on the wave equation, refraction, lenses and stationary waves.
298 words, about 1 min05Electricity, Magnetism and Electronics
Electricity, magnetism and electronics tests circuit analysis, electromagnetic induction and the behaviour of semiconductor devices. Expect calculations with internal resistance and simple operational-amplifier or logic circuits.
294 words, about 1 min06Atomic Structure, Bonding and Chemical Reactions
Atomic structure, bonding and chemical reactions brings together electronic configuration, chemical bonding and quantitative reaction chemistry. The exam rewards precise use of the mole concept and correct ion charges.
291 words, about 1 min07Organic Chemistry and Polymer Materials
Organic chemistry and polymer materials tests functional-group chemistry, nomenclature and the link between monomer structure and polymer properties. Expect reaction-type identification and simple polymer calculations.
257 words, about 1 min08Cell Biology, Genetics and Microbiology
Cell biology, genetics and microbiology tests structure–function relationships, inheritance ratios and safe handling of microorganisms. Diagrams and calculations both appear.
265 words, about 1 min09Applied Biology, Agriculture and Biotechnology
Applied biology, agriculture and biotechnology applies biological principles to food production and industry. Questions test nutrient management, propagation, pest control and fermentation.
261 words, about 1 min10Technology, Instrumentation and Engineering Applications
Technology, instrumentation and engineering applications tests how physical principles become measurement and control systems. Expect sensor selection, signal processing and system-level reasoning.
