Assessment 2 & 3 make up the steps of your research project.

In Assessment 2, you identified the soil forming factors at your sites in part 2. Now, for part 3, you need to develop predictions for the soil features you will be testing at your sites. The soil features you will be testing are soil colour, pH, texture, bulk density, dispersion, slaking, infiltration and organic matter (soil organic carbon).

You need to identify 20 predictions to receive full marks. To pass this assessment you must include at least one prediction for each soil feature.   

Your predictions may be referenced with information from the modules but will receive more marks if supported by scientific literature.

You should also ensure that you explore the role of all five soil forming factors.

Assessment 3 will require you to discuss the role of soil forming factors on the features of your soil, based on your predictions and results. When you discuss your results use peer-reviewed references to support your statements.

For the full version of instructions around this assessment, please refer to your subject outline.

A topic analysis will help you to clarify and understand what your assessment question is asking you to do.

You will generally be given three key pieces of information:

1. The key topic or concept words direct you in what to research.
2. The limits or qualifiers tell you the specific focus of the topic or concept.
3. The task or instruction terms tell how you are to deal with the content. Charles Sturt University has a list of explanations for common instruction words.

Let's start thinking about what terms you will use when searching for information. To do this:

• Identify the key concepts of your topic (watch the topic analysis video for assistance); and then
• Brainstorm as many synonyms and similar terms/phrases as you can.

This is a useful exercise because the language used to describe your topic may vary from source to source, and you don't want to miss out on a good source because it uses a different term to the one you are searching on.

Let's use this topic as an example:

Effects of organisms (vegetation/organic matter) on soil colour

Write down the key concepts from your topic and have a go at brainstorming as many alternative keywords and phrases as possible.

Tip: Online dictionaries and thesauri can help you identify synonyms.
