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

Here we were waiting for all the students to come.

You can see a jar and two bottles with the water

This isn’t good at all…

A new filter is prepaired for another sample.

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…

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?
