pH TEST: - SOIL TEST 1
Today during lunch time I conducted a test on soil pH.
  1. To begin with, I gathered the required equipment needed; data logger, pH probe, 5 small beakers, 1 dropper bottle of dimineralised water and a dish spoon.
  2. Firstly, I dished out a small amount of soil from each of the 5 samples into each of the 5 small beakers.
  3. Then I added some dimineralised water to each of the soil samples in order for it to become a liquid - easy to test.
  4. After this, I tested each of them by using the pH data logger. I made sure that the end of the data logger (pH probe) did not touch the bottom of the beaker, I also made sure that it was just partially touching the surface, not all the way down hitting the bottom of the beaker. This determines the pH level of the soil being sampled.
  5. Lastly, record results into table form

results shown below;

Soil beaker: 1
pH: 5.75

Soil beaker: 2
pH: 6.39

Soil beaker: 3
pH: 6.18

Soil beaker: 4
pH: 6.08

Soil beaker: 5
pH: 6.30
