Cambridge Progression Test Stage 3 Science 2022 Paper 2 With Mark Scheme

1. Plant parts and function: labeling roots, understanding stems transport water, observing flower color change with colored liquid
2. Forces and movement: push/pull classification, skateboard speed increase downhill, friction slows motion, water resistance in puddles
3. Materials and their uses: identifying strong, hard, heat-conducting materials for bridges and saucepans, choosing soft or dissolvable materials for clothing
4. Scientific investigations and fair testing: plant height growth based on distance from light, balloon rocket powered by air, towel absorbency experiment with bar chart
5. Energy and changes: pulse rate prediction after exercise, conditions for a fair test (same exercise, same time), importance of daily physical activity
6. Classification and grouping: animal classification by wings and habitat, living vs. once alive vs. never lived, sense organ for smell, plant wilting from dehydration
