Cambridge Progression Test Stage 7 Science 2018 Paper 2

1. Biology: bat adaptations (flight, insect capture), mouth specialization, vertebrate classification (ostrich traits), food chain construction (phytoplankton → crustacean → fish → dolphin → killer whale), seed length variation and histogram, species variation and measurement.
2. Chemistry: material properties for scooter parts (steel, rubber), boiling to sterilize broth (Pasteur’s experiment), change of state (ice melting, temperature pattern), Universal Indicator usage and pH meaning, metal vs non-metal properties (conductivity, malleability).
3. Physics: Sun’s apparent movement (Earth’s rotation, tilted axis), Earth layers (core, mantle, magma, igneous rock), forces on a moving truck (driving force, weight, gravity), friction and lubrication (ice skates), energy forms (chemical, thermal, kinetic, elastic, gravitational).
4. Earth science: seed histogram plotting, planet orbit and revolution time (Jupiter vs Mercury), planetary gravity comparison (weight vs mass), use of materials (aluminium for lightness, corrosion resistance), volcano rock formation from magma.
5. Scientific skills: data interpretation (anomalous result, mean time), energy transformation sequences, tally chart completion, histogram labeling, drawing force arrows, experimental method explanation (e.g. using indicator, measuring seed length).
