Section B
Question 1
(a) Because animals in cage Z is more active than animals in cage Y //
Cage Z puts under sunlight than cage Y puts indoor
(b) Decrease, increase, decrease, increase, decrease
(c) 1. Time
2. Air temperature of animals cage
3. Type/size/number of animals
(d) The air temperature in cage Z higher than air temparature in cage Y / (vice versa)
Question 2
(a) To study/investigate/find out the relationship between the time/position of the sun and/with direction of the shadow.
(b) Time // Position of the sun // direction of the shadow // height of pupils /Kelvin / place of the investigation.
(c) Position of the sun is at the west, direction of the shadow is at the east / (vice versa)
(d) Because the rotation of the Earth on its own axis from west to east.
Question 3
(a) To study/investigate/find out the relationship between the size of container/surface area and/with volume of water after one hour.
(b) Volume of water in each container decreasing because the water evaporate to the surrounding.
(c) Air humidity // Air movement // Surrounding temperature
(d) The sorrounding temperature increase / more, the volume of water left decrease / less // (vice versa)
Question 4
(a) Because Q is having total eclipse // umbra.
(b) Surrounding temperature decreasing // the Sun suddenly disappear.
(c) Light travels in straight line / cannot pass through opaque object.
(d) To study/investigate/find out the relationship between the time and/with stages of the eclipse.
Question 5
(a) To study/investigate/find out the relationship between the type of harvesting methods and/with amount of harvested crops.
(b) Methods K take shorter time.
(c) It use more time / energy.
(d) Technology / machines makes works easier / faster.
