Last week our headteacher, Mrs. Ames, made Class N do a presentation on 2006 science SAT paper A page 16 question 7. Every table did their own thing, including low-budget productions, PowerPoint prresentations, TV shows and demonstrations. The question sees Josh and Safia put a cold plate with ice cubes on top on a bowl of hot water. Soon water drips from the plate. If the ice cubes melt the water cannot seep through the plate. Why did the droplets appear? Quite simple if you understand evaporation and condensation.
