1. Digestive system function, zebra adaptations (eyes at side, stripes), oesophagus identification
2. Types of forces: gravity, friction, air resistance, normal, applied; floating boat force balance
3. Dissolving: solute, solvent, reversibility, water freezing below 0 °C forming ice
4. Atmosphere and space: air layer = atmosphere, gases = nitrogen, oxygen, orbit shape = ellipse
5. Classification: seed vs. non-seed plants, algae vs. mosses difference, tulips as flowering plants
6. Reindeer cold-climate adaptations: double fur insulation, flat feet support, anti-slip feet fur, nasal heat exchange
