2 AJC 2018 JC2 H2 Geography Preliminary Examinations – Paper 2 Section A Theme 4: Geographical Investigations 1 A class of 25 18-year old students were task ed to investigate the influence of land use on infiltration rates in Singapore. After spli tting into groups of 5, one of the groups selected Labrador Nature Reserve as their st udy area, and decided to carry out their primary fieldwork at two sites – Sites A and B – in the nature reserve. The group crafted the following hypothesis for their investigation: “The higher the level of urbanisation of th e site, the lower the infiltration rate in the site.” The following equipment were provided to measure infiltrati on rate at the two different land use sites: • A tin can, about 30cm in height and a di ameter of 10cm, with both ends removed • A 1.5-litre bottle of water • A ruler • Hammer • Wooden plank • Stopwatch The investigation was conducted on a weekday afternoon in June. They were given 3 hours to complete their investigat ion, from 2 pm to 5 pm. At the respective sites, the tin can was driven into the soil to about 10cm deep by using a hammer onto a wooden plank placed on the rim of the can. A ruler was placed vertically inside the tin can to record the fall in water level. Water wa s poured to a depth of 20 cm. Measurements of the remaining depth of water was taken every 1 minute to compute the infiltration rate. At the same time, constant top-ups of wate r were carried out to maintain a regular head of water above soil. Resource 1 shows a map of Lab
