1. W ater analysis A very interesting activity in the Virtual Eden project… Everything was to collect some water samples from any river or lake and then to make some simple analysis of that water. So, after we had collected three samples, some of the students in our school came into the chemistry laboratory to analyze them…

2. You will see now some photos of the students working…

3. Here we were waiting for all the students to come. You can see a jar and two bottles with the water samples.

4. You can see the filter before and after the water has been poured through it. There really are lots of residues in the water, aren’t there? This isn’t good at all…

5. A new filter is prepaired for another sample.

6. The cilinder is very useful for many types of analysis. You can see how the students used it to determine the density of the water. The density−meter is also a very interesting tool…

7. It has been taken from the Danube, which comes in Romania after passing through other ten countries… This water doesn’t look too clean, does it?

8. This has been only a very small part of the Water Analysis activity. But even from theese pictures I’m sure you could see how interesting it has been. The entire Virtual Eden project is very interesting so we are all happy to join it. Click here to exit presentation
