Cambridge Progression Test Stage 4 Science 2023 Paper 2 With Mark Scheme

1. Human body and movement: labeling bones, muscle pairs (contract/relax), exercise benefits (e.g. stronger lungs or bones)
2. Volcanoes and Earth structure: magma chamber, lava flow, secondary cone, earthquake as sudden crust movement
3. Particle model and matter: properties of solids and liquids, sugar grains as solid that flows, energy and state changes (melting, freezing)
4. Electricity and circuits: incomplete circuit explanation, increasing lamp brightness, reflection of light from non-light source, correct ray path
5. Food chains and habitats: producer = leaf, herbivore = caterpillar, snake eats chameleon, mongoose = predator and carnivore, bird beak adaptations
6. Energy transfer: sound from speaker, heat from cooling object, energy conservation (not created or destroyed) through various forms of transfer
