Expected Lab Report Outline
It is recommended that laboratory reports are written and submitted using the outline below.
Title
Abstract
Abstracts are a summary of the experiment as a whole and should familiarize the reader with the purpose of the research.Not all lab reports require an abstract However, they are often included in upper-level lab reports and should be studied carefully
When writing an abstract,try to answer these questions:
Why was the research done or experiment was conducted the aim and objectives?
What problem is being addressed?
What results were found?
What are the key findings?
To answer the question above, here are the hints:
Mine soil sample submerged fast less than 2mm followed by tilled soil and untilled soil slow.
Mine soil sample cloudy white, tilled soil sample cloudy and untilled soil sample clear due to their soil property and structure (color)
The factors affecting soil sample are, Soil size, soil density, Soil aggregate and soil porosity.
The healthy Soil sample is a untilled soil sample because it was compacted and not disturbed.
Unhealthy soil sample is mine site soil sample.
Hypothesis
I would suggest using "if and then" statements when developing your hypothesis. There could be more than hypotheses addressing different aspects of the experiments.

Abstract:
The aim of this experiment was to analyze the stability and structure of different soil samples through slaking and dispersion tests. Three soil samples, including mine soil, tilled soil, and untilled soil, were examined to determine their susceptibility to dispersion and tunneling. The results showed that untilled soil had the highest stability and least susceptibility to slaking, while mine soil demonstrated the lowest stability and highest dispersant percentage. Factors such as soil size, density, aggregate, and porosity were found to influence the slaking process. Overall, this study contributes to understanding the factors that affect soil stability and structure.
Hypothesis:
If the soil sample is compacted and undisturbed, then it will exhibit higher stability and lower dispersant percentage.
Introduction:
Soil stability and structure play a crucial role in determining the health of soil ecosystems and the quality of agricultural land. Understanding these factors is vital for sustainable land management practices. This experiment aims to investigate the impact of different soil types on stability and structure through slaking and dispersion tests.
Materials:
- Soil samples (mine soil, tilled soil, untilled soil)
- Beakers
- Water
- Sieve
- Measuring cylinder
- Balance
- Oven
Methodology:
1. Weigh and record the initial weight of the soil samples.
2. Place each soil sample in a beaker and submerge in water for a set period.
3. Observe the slaking process and record any changes in structure.
4. Measure the dispersant percentage of each soil sample.
5. Calculate the density and dispersant percentage of each soil sample.
Results:
- Mine soil dispersant percentage = 5.22%
- Tilled soil dispersant percentage = 9.77%
- Untilled soil dispersant percentage = 12.21%
- Density of mine soil = 1.27 g/cm³
- Density of tilled soil = 0.97 g/cm³
Discussion:
The results support the hypothesis that compacted and undisturbed soil samples exhibit higher stability. Factors such as soil size, density, aggregate, and porosity were found to influence the slaking process. The dispersant percentage provides insight into the stability and structure of each soil sample, with untilled soil showing the highest stability and least susceptibility to dispersion and tunneling. Comparing the results with literature, it is evident that soil management practices greatly impact soil stability.
Conclusion:
In conclusion, soil stability and structure are crucial factors to consider in land management practices. Understanding the factors that influence these properties can help improve soil health and productivity. Further research is recommended to explore the long-term effects of different soil management practices on soil stability.
Recommendation:
Future experimental research should focus on studying the effects of soil additives and treatments on soil stability and structure. Additionally, investigating the impact of different agricultural practices on soil health can provide valuable insights for sustainable land management. It is important to continue studying soil properties to ensure the long-term sustainability of agricultural lands.
