One-Word Answer Questions
12. What is a natural magnet called?
Lodestone
13. Which pole points north when a magnet is suspended?
North
14. What is the process of settling solids called?
Sedimentation
Diagram-Based Questions
15. Draw the magnetic field lines around a bar magnet. 
Field lines emerge from the north pole and enter the south pole.
16. Draw a filtration setup to separate sand from water. 
Sand is trapped by filter paper, and water passes through.
Case Study Questions
17. Riya observed that iron nails stick to a bar magnet but not to a wooden stick. She also noticed that when she mixed sand and iron filings, a magnet could separate them. What can she infer about magnets?
Magnets attract iron and can be used to separate iron from mixtures.
18. Amit found that pouring water into a mixture of mud and water caused the mud to settle at the bottom. He then poured the clear water into another container. What separation methods did he use?
Sedimentation and decantation.
19. During a science fair, Priya used a sieve to separate pebbles from flour. Later, she used winnowing to remove husk from grains. What did she learn about separation methods?
Different methods are used based on the size and weight of materials.
20. Karan noticed that salt dissolved in water did not separate with a filter. He heated the mixture, and salt remained. What method did he use?
Evaporation
