Science — MYP 4

International Baccalaureate · Ages 14-15

MYP 4 usually separates biology, chemistry and physics into distinct courses, and the content aligns closely with IGCSE or the first year of a two-year secondary science programme.

Biology covers cells, transport, enzymes, genetics and ecology; chemistry covers atomic structure, bonding, the mole and reaction types; physics covers mechanics, energy, waves and electricity with full quantitative treatment.

Laboratory work is formally assessed against the MYP criteria, with students designing their own investigations and evaluating method and data quality in detail.

Key topics covered

• Cells & TransportCell structure, diffusion, osmosis, active transport and enzymes.
• Genetics & EcologyDNA, inheritance, variation, ecosystems and human impact.
• Atomic Structure & BondingElectron arrangement, ionic and covalent bonding and structure.
• Quantitative ChemistryThe mole, reacting masses, concentration and balanced equations.
• Mechanics & EnergyNewton's laws, momentum, work, power, energy transfer and efficiency.
• Waves & ElectricityWave properties, the EM spectrum, circuits, resistance and power.
• Experimental DesignIndependent investigation, uncertainty, data processing and evaluation.
