Soil was our focus of the week. We looked at a range of things such as the different variations of soil, how soil can be formed and where exactly it is used on our planet.
So did you know that the list below are actually Victoria’s main ecosystems?
✤ the alps ✤ grasslands ✤ heathlands ✤ the mallee ✤ dry forests and woodlands ✤ inland waters and wetlands ✤ the coast ✤ marine environments ✤ urban ✤ agricultural
In the lecture this week Jenny showed us this picture below. It shows us the different types of soils in Australia and where exactly they are found. I’m just guessing from the picture here, but I am from Bendigo in Victoria and I think the type of soil found there is Sodosol.

So how exactly is soil created? Well there are a few steps in the process of soil formation. These are;
1. Lava cools and forms igneous rock
2. Weathering (occurs physically and chemically)
3. Particles then transported by wind or water
4. Particles are deposited
5. Plants take hold
6. Organic matter and soil organisms contribute nutrients
I found this quick clip on YouTube explaining the formation of soil. The video is for children and I would hope to use it in my classroom one day!

As a reading we looked at the ‘Working with Soil’ booklet complied by Landcare Queensland. This would be a useful tool for students of all ages when researching further into soil. One thing I learnt from the booklet was about the composition of soil and what actually makes up soil, as I’ve never really thought too much about it. There are 5 main components;
'The dynamic problem of pollution' was the topic this weeks group presented on. Pollution was defined as the introduction of contaminants into the natural environment that cause change. Pollution is not just one thing though, it can come in many different forms, some of those being air, water, soil and radioactive pollution. A central issue that has been cause by pollution is the health of humans, especially through air pollution. When the air is polluted with chemicals and all the smoke you see coming from industrial areas, this can sometimes cause severe respiratory problems.
- Mineral particle (mainly sand, slit and clay)
- Organic matter (dead and decaying plants and animals)
- Water
- Air
- Organisms (living things)
