Guiding Question

How much water do we use in Germany/Greece and what for ?

Aims

- Develop a chart so as to proceed into comparing the amount of water used in Germany and Greece respectively.

- Produce a data table to compare the use of water in the two countries.

- Develop an article and describe in it the similarities and differences resulting from the graphs.

Process

- Search for the relevant information concerning your country (ask your teacher to help you) and create the chart.

- Write the article while you keep on communicating with your e-twinning partners either via e-mail within Twinspace or via chat when you both seem to be online.

Shared thoughts and comments by the teams in Germany and Greece :

Is your household water table for 4 persons per day?               Viola Germany

 

The chart that we created along with the German e-twinning team, present similarities as well as differences.

One of the latter shows that in Greece there is a gradual rising cost when a household tends to consume large quantities of water. The Greek state attempts to discourage water-waste and make people realize how valuable it is and vital for the survival of mankind.
