Ecology I:
Experiments with water
93 pages, A4 size
33 experiments on the chemistry of water. The
experiments are designed so that they can be
carried out by the students themselves. Clean
and polluted water from natural sources is
compared. The effects of pollutants on plants
and animals are evaluated using comparison
tables.

Ecology II:
Experiments with air and soil
67 pages, A4 size
10 experiments on soil analysis and 14 experiments
on air investigations. The experiments
are aimed at comparing unpolluted samples
with polluted samples so that in addition to the
actual analysis of the material it will be possible
to estimate the extent of the impact a particular
pollutant has on the natural environment.
