Topic 5: MYP eAssessment structure and on-screen examination topics (examples)
- What is the structure of the MYP Sciences eAssessment?
- An on-screen examination in biology, chemistry, physics or integrated sciences, with three tasks: knowing and understanding (criterion A, 25 marks); investigation skills (criteria B and C, 50 marks); applying science (criterion D, 25 marks).
- Which eAssessment task carries the most marks?
- Investigation skills (criteria B and C), worth 50 marks — half the total. Practise designing, processing and evaluating investigations, not just recalling content.
- Which topics can the sciences on-screen examination draw on?
- Examples include atomic structure and bonding, cells, cycles, electromagnetism, evolution, interactions between organisms, forces, states and properties of matter, metabolism, organisms and waves. Which apply depends on the option you are entered for.
- Discrete, modular and integrated science courses
- Discrete: biology, chemistry and physics taught as separate subjects. Modular: two or more sciences taught in rotation. Integrated: disciplines blended together. The same four criteria apply to all three.
- Isotopes
- Atoms of the same element with the same number of protons but different numbers of neutrons.
- Mass number versus relative atomic mass
- Mass number: protons + neutrons, a whole number for one isotope. Relative atomic mass (Aᵣ): the weighted mean mass of an element's atoms relative to 1/12 of a carbon-12 atom, often not a whole number.
- Ionic versus metallic conduction
- Ionic compounds conduct by moving ions, only when molten or dissolved. Metals conduct by moving delocalised electrons, as a solid or liquid.
- Intrusive versus extrusive igneous rock
- Intrusive: cools slowly underground, giving large crystals (granite). Extrusive: cools fast at the surface, giving small crystals (basalt).
- How do MYP Sciences criteria B and C prepare you for the DP?
- Formulating a research question, designing a fair method and processing and evaluating data map onto the internal assessment of the DP sciences.
