QUESTION 1 1.1. Scientist designed an experiment to investigate the water holding capacity of sand, loam and clay soil. Soil samples from these soil types were placed in funnels lined with filter paper. 100m of water was added to ALL three soil samples at exactly the same time. The filtrates were collected in measuring cylinders. The results are shown in the following table. Volume of filtrate (in cm”) Time (in minutes) Loam Clay 0 2 4 6 8 10 20 40 60 Sand 10 20 35 50 65 75 10 20 35 45 55 60 65 0 5 10 12 14 16 75 75 (3) 1.1.1. State a possible hypothesis for this experiment. 1.1.2. Identify: (a) the dependent factor (b) any TWO fixed variables 1.1.3. Which type of soil will be most suitable for gardening?
