(b) List three materials that could be used in carrying out the experiment in the set-up F.
(c) Outline three steps invo?ved in carrying out the experiment.
(d) Name four soil components observed in the experimental set-up.
(e) Draw and label the experimental set-up.
(a)
Aim of the experiment set-up F:
- Determination of Soil texture by sedimentation/sedimentation experiment
(b)
Materials that could be used in carrying out the experiment in the set-up F:
- Soil sample
-Measuring cylinder
- Beaker
- Glass jar
- Water
- Glass rod/ stirrer
- Hydrogen peroxide/Calgon
(c)
Steps involved in carrying out the experiment:
- Put a quantity of soil sample in the measuring cylinder,
- Water is added to the soil sample in the measuring cylinder
- Hydrogen peroxide could be added to break soil lumps
- The content in the measuring cylinder is n stirred with a glass rod/shake vigorously
- The content is allowed to settle for some hours.
(d)
Soil components observed in the experimental set-up:
- Coarse sand
- Silt, Water
- Fine sand
- Clay
- Organic matter
