Topic/ Themes for project Work on disaster Management-
Do any one of the following-
Project 1-Role of Govt./Non-Govt. functions in your locality in Disaster management
Interview any two of the Govt. non- government functionaries in your locality on their role in Disaster
management.

shopkeepers, housewives, senior citizens, college students, etc.) in your locality on the hazards
prevalent and preventive measures they have taken or would like to take to reduce the impact.
Prepare a survey report highlighting the areas where awareness is needed and the local resources
available in the locality to create awareness.
The student can select any two of the functionaries based on their availability
In that city/town.
Project -2 Preparation of Models of Disaster resilient Structures
Make layouts of models based on structural improvement in buildings in a rural/urban community in coastal
areas prone to floods/cyclones or in areas prone to earthquakes/landslides. Show the special features of the
buildings and indicate the early warning system that could be best used in that community.
Note: To carry out the project there is need to have a good understanding about the subject . The class X
textbook on Disaster Management will help the teachers and the students to have fair understanding about the
topic. However the student also need to seek support from qualified engineers, and architects who have
knowledge on safe construction practices from either the Government or private sector and also from
academic institutions.
Discuss- *Factors causing Earthquake, cyclones, floods landslides.(Any one)
Houses vulnerable to Earthquake, cyclones, floods landslides.
Signs and Warnings
Protection measures to be taken.
Project -3 Pocket Guide on First Aid-
Prepare a pocket guide on First Aid for your school. The First Aid pocket guide should contain aids that need to
be given for Fractures, Poisoning, Cuts and Burns, Heat and cold Wave and other threats that are prevalent in
that area. The content shared in the guide should be supported with adequate pictures so as to give a clear
and elaborate understanding about the topic. Choose awareness campaign strategy for either senior citizens
or illiterate people and prepare a brief write up.
Note ; Doctors, Local health practitioners, trained volunteers of Red Cross and professional from other
agencies/bodies/institutions. Proficient in this field can be consulted to prepare the first aid pocket guide.
Discuss: *What are search and rescue skills and objectives of search and rescue teams.
Who should be the members of the team?
The precautions to be taken while rescuing a person.
What is First Aid?
What should be first aid for Fainting, Burns, Bleeding, Frost bite, Electrocution, Fractures and sprains, poising, heat stroke, dog bite and snake bite.
Teachers report in the given Performa will be attached at the end of the report.
