SPM Additional Science study guide

SPM Additional Science · Work through your exam, one topic at a time.

SPM Additional Science is a Malaysian upper-secondary elective taken alongside core Science, aimed at students who want a stronger grounding in physics, chemistry and biology than the compulsory Science syllabus provides. It suits candidates planning to enter science-based pre-university programmes, matriculation, or technical fields, and those who simply want a wider scientific literacy. The SPM Additional Science study guide has 10 sections and about 2,979 words.

01

Scientific Skills and Investigation

Scientific Skills and Investigation examines how you plan, carry out, record and evaluate an experiment. SPM questions ask you to identify variables, state a hypothesis, tabulate data, plot graphs and draw conclusions supported by evidence, not opinion.

02

Matter and Atomic Structure

Matter and Atomic Structure tests particle theory, states of matter, atomic models, electron arrangement, isotopes and the Periodic Table, plus separation of mixtures. Kinetic particle theory: particles in solids vibrate about fixed positions; liquids slide past each other; gases move randomly and are far apart.

03

Chemical Reactions and Equations

Chemical Reactions and Equations tests balanced equations, mole calculations, acids, bases, salts and common reaction types. Physical changes are reversible and make no new substance; chemical changes make new substances and are usually irreversible.

04

Forces, Motion and Energy

Forces, Motion and Energy tests kinematics, Newton's laws, momentum, work, energy, power, efficiency, pressure and elasticity. v = u + at; s = ut + ½at²; v² = u² + 2as.

05

Electricity and Magnetism

Electricity and Magnetism tests circuits, Ohm's law, electrical energy, electromagnetism, motors, electromagnetic induction and transformers. Current I = Q/t is measured in amperes with an ammeter in series.

06

Waves, Light and Sound

Waves, Light and Sound tests wave properties, reflection, refraction, diffraction, interference, sound, lenses and optical applications. v = fλ; period T = 1/f; amplitude is maximum displacement; wavelength is the distance between successive crests.

07

Cell Biology and Life Processes

Cell Biology and Life Processes tests cell structure, microscopy, transport across membranes, enzymes, photosynthesis, respiration and cell division. Animal cells have a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.

08

Coordination, Homeostasis and Reproduction

Coordination, Homeostasis and Reproduction tests nervous and hormonal control, feedback mechanisms, human reproduction and contraception. The CNS is the brain and spinal cord; the PNS is the peripheral nerves.

09

Ecology and Environmental Science

Ecology and Environmental Science tests ecosystems, energy flow, nutrient cycles, species interactions, pollution and conservation. Organism → population → community → ecosystem.

Technology and Applications of Science

Technology and Applications of Science tests how scientific principles are used in biotechnology, energy, materials, medicine and communication, including benefits and risks. Biotechnology uses living organisms or enzymes.
