Cambridge Progression Test Stage 3 Science 2022 Paper 1 With Mark Scheme

1. Human organs and digestion: identifying stomach, lungs, brain, intestines; intestines absorb nutrients from food in the abdomen
2. Forces and motion: friction is a force between surfaces that makes movement harder; gravity pulls objects toward Earth’s center
3. Transparency of materials: predicting light behavior through transparent materials; classifying bubble wrap, cloth, plastic, glass, foil, black paper
4. Moon and space knowledge: identifying a full moon, knowing the Moon takes 28 days to orbit Earth, recognizing Earth as spherical
5. Food chains and producers/consumers: maize and carrot as producers, fox and owl as animal consumers, food chain B longer due to more organisms
6. Magnetism and magnetic behavior: correctly identifying south pole, attraction and repulsion between magnets based on pole positions
