PAPER II - PRACTICAL/PROJECT WORK
(Classes XI and XII)
The practical/project work carrying 30 marks needs to
be undertaken under the guidance of the teacher. The
project will be evaluated by a Visiting Examiner
(who has specific expertise in the content of the
project work) appointed locally and approved by the
Council.
The project work could take one of the five forms:
1. Address a current environmental problem
(preferably at local or regional scale) and should
include problem identification and analysis, use of
secondary data as well as some collection of
primary data, design of solution, documentation of
the entire process in the form of a solution
proposal.
2. Design and conduct an environment impact
assessment. The candidates may use secondary
data, demonstrate their capacity to collect and
analyse primary data by incorporating some
primary data collected and use it in a few sectors
of their work.
3. Systematic monitoring of an aspect of the local
environment over a period of at least six months.
The candidate must use quantitative techniques of
monitoring, sampling scientifically. The data
collected must be interpreted and presented in the
report.
4. Field work and training in an environmental
organisation (NGOs, Industrial Pollution Control
Firms, Testing Laboratories, etc.) for a period of
not less than one month. This work should be
focused on one area in the syllabus. The candidate
will produce a paper on the area of his/her work
and training which will include his/her experience
and the special expertise that she/he has acquired.
5. Conduct a study on the density and population of
plants growing in a particular area using the
quadral method.
OTE: o question paper for Practical work will
be set by the Council.
