Land analysisOne of the goals of the

Virtual Eden project is trying to make the real world a little Eden. If we want our world to be an Eden, we will have to understand that it needs our help, we will have to see what will happen if nobody takes care of the world.

How to understand this?

Let's take a small piece

of land from

somewhere and put it

in a jar. Then, let's go

with it in the chemistry

laboratory and see...

We need to find out what is

the pH of the land.

To do this, first we must

mix it with water,

because we can't do

anything with the litmus

paper on dry dirt.

After mixing the dirt with water, students

started the next step of the analysis.

They filtered the mixure to obtain a clear liquid that could be analysed.

By simply inserting the litmus paper in that water with the soil extract,

we found out the pH for each of

the land samples.

This sounds simple, but don't forget we had to go and collect ground samples before doing the analysis!...
