Methods of data collection
The field work was carried out in Upper Canada College on Wednesday, Jan, 5th, 2011. The equipments we used in the field work are electric scale, 2 measuring cups, 1 tablespoon, soil, water, 1 laptop, 2 vernier thermometers and 1 USB cable.
The following are the procedures for the field work.
1. Prepare two tables for recording the weight and the change of temperature.
2. Get two plastic cups, and use the electric scale to measure the weight of both cups, and fill in the table.
3. Add a full cup of soil and water into the cup, and measure the weight again, fill in the table.
4. Calculate the weight of the water and soil by subtracting the weights gained second time by that of the first time, fill in the table.
5. Place both of the soil cup and water cup outside in order to match the temperatures of soil and water.
6. Bring in the soil and water sample, use logger pro to record the change of temperature. Record temperature every single 30 second in the table.
7. Use Microsoft Excel, and copy the data and then create the diagram.
