What: To observe and measure core samples of soil to see how soil properties change with depth
Where: Forest behind SST
When: morning, afternoon and night times of everyday
(a) Independent variables: time
(b) Dependent variables: soil quality
(c) Constant variables: Soil characterisation field guide, the place where experiment will be conducted
Hypothesis:
If I use the soil characterisation field guide to identify the soil structure, then I will be able to find out the soil quality at different times of the day.
