creative use of materials.

3. The project report will be presented in a neatly- bounded folder OR spiral binding.

Preparation and Submission of the project work:

The project report will be developed and presented in this order:

1. Cover Page showing Project Title, Student information, School and Year. 2. List of Content with Page numbers 3. Acknowledgement ( acknowledging the institution, Offices and libraries visited and persons who have helped)

4. Chapters with relevant headings 5. Bibliography should have the title, Page referred, author, publisher, year of publication and if a web

site, the name of the website with specific website link which has been used. 6. All the photographs and sketches should be labeled and acknowledged. 7. Teacher’s evaluation report- 8. Last date of submission is 30th June 2015

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.

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.
