Science — MYP 3

International Baccalaureate · Ages 13-14

MYP 3 Sciences is often the last year of integrated science before biology, chemistry and physics separate in MYP 4 and 5. Content is correspondingly broad and more demanding.

Biology covers cells, genetics and ecosystems; chemistry covers atomic structure, the periodic table and chemical reactions with equations; physics covers forces, energy, waves and electricity with quantitative work.

The processing and evaluating criterion now expects proper graph work, identification of anomalies and a reasoned evaluation of method: the skills the Diploma sciences assume from day one.

Key topics covered

• Cells, Genetics & EcosystemsCell division, inheritance, variation, energy flow and interdependence.
• Atomic Structure & the Periodic TableAtoms, ions, groups, periods and periodic trends.
• Chemical ReactionsWord and symbol equations, reaction types and conservation of mass.
• Forces & EnergyNewton's laws, momentum, work, power and efficiency with calculation.
• Waves & ElectricityWave properties, sound, light, circuits, current and voltage.
• Investigation & EvaluationGraph work, anomalies, uncertainty and reasoned evaluation.
