OR - He wanted to find out if the size of population of organisms living in a pond is affected by the amount of carbon dioxide in the water.

34b - Organism C. Its population size increased when the amount of carbon dioxide increased (1m), showing that they were reproducing due to an increase in rate of photosynthesis / they photosynthesise more (1m).

39b - When the temperature of the water in the basin increases, the time taken for the two drops of ink to reach P and Q decreases.
OR - When the temperature of the water in the basin decreases, the time taken for the two drops of ink to reach P and Q increases.

40b - Point E. It cooled faster along EF than DE.

41a - 0% -X, Z, 100% - Y
41b - Good conductors of heat / Conductors of electricity: iron grille, aluminium can
Poor conductors of heat / Insulators of electricity: mirror, clear plastic, glass bulb, spectacle lenses, frosted glass, handkerchief, rice paper
OR - Magnetic: iron grille
Non-magnetic: aluminium can, mirror, clear plastic, glass bulb, spectacle lenses, frosted glass, handkerchief, rice paper
OR - Flexible: handkerchief, rice paper
Non-flexible: iron grille, aluminium can, mirror, clear plastic, glass bulb, spectacle lenses, frosted glass
OR - Metals: iron grille, aluminium can

44a - Any number between 6 and 9 i.e. 7 or 8
44b - Fewer fish was needed to be thrown into the sea as during high tide, the water level is higher and so the boat can float more easily.

45a - Iron / Steel / Nickel / Cobalt / Lodestone
45b - Bar P is made of a magnetic material (1/2m) and is attracted to the magnet. Magnetism is able to pass through glass (1/2m) which is not a magnetic material.
OR -Bar P is attracted to the magnet (1/2m). Magnetism is able to pass through glass (1/2m) which is not a magnetic material.
(if answer to (a) is lodestone)

46a - It tilted downwards to Container P. There are two holes in Container Q. Hence, the water in Q flows out at a faster rate (1m) than P, making Container Q lighter than P (1m).

46b- Move Container P nearer to the centre of the balance.
OR- Move Container Q further away from the centre of the balance.
OR - Move the string nearer to P.
