Main Theme : Science , Society and Environment

Sub-themes: The six sub-themes are:

Given below are number of ideas for designing the exhibits on different sub-themes in the context of the main theme. However, these ideas are only suggestive in nature. Participants are free to design exhibits based on other related ideas on the given sub-theme.

Sub Theme-1                   Agriculture and Food Security

Agriculture, directly or indirectly, has been the main source of livelihood for majority of Indian population. One of the greatest assets in rural areas could be an intelligent and effective use of emerging technologies such as biotechnology, microbiology, genetic engineering, etc. The agricultural activities that lead to food production are no longer a subject of classical farming only. The modern agriculture cannot sustain itself without the support of research work done by scientists. With the help of science and technology, we can enhance our agricultural knowledge to achieve food security to reduce hunger, malnutrition and poverty, and facilitate equitable, environmentally, socially and economically sustainable development.

The exhibits/models in this sub-theme may pertain to:

Sub Theme-2                  Energy- Resources and Conservation

After food and water; energy is our most basic need. All activities require energy to perform. Energy is an important concern that differentiates the global rich and the global poor. All conventional sources of energy are exhaustible. At the current rate of consumption, known reserves of petroleum will be exhausted in about 35 years, natural gases in about 50 years and coal sometime within 200 years. The great concern about energy is not about diminishing supplies. It is rather than our current models of harnessing energy that are unsustainable because of environmental, economic, geographical and equity issues. One of the important and obvious way of redesigning system for harnessing energy is to develop and shift to clean and nonconventional energy resources which are either non exhaustible or renewable as solar energy, wind energy, hydroelectric power, geo-thermal energy, energy from biomass and biogas, ocean thermal energy, wave energy and energy from other emerging technologies.

This sub-theme is expected to make the children think of various ways and means for making efficient use of available energy resources and also new techniques/methods of using and conserving energy from both conventional and nonconventional sources.

Sub theme-3                                      Health

Our health is continuously under the influence of both endogenous (within) and exogenous (around) environment and therefore a matter of great concern especially in the rapidly growing society to cope up with newer scientific and technological inventions. Our health is adversely affected due to many environmental hazards that lead to several kinds of infections in the body. With increasing population, demand for food, water, home, transport, energy etc are increasing causing tremendous pressure on our natural resources and thereby contributing to pollution of air, water and soil. The lifestyle including food and water we take, tendency for junk/ fast food, rest and exercise, habits and drugs and alcohol abuse is another challenge to our health.

The present sub-theme is proposed with the objectives: to bring awareness among the youth about health and factors affecting our health, to explore new scientific, technological and biomedical interventions in prevention and cure, to analyze the role of self and society in keeping our environment healthy in order to maintain good health and promote innovative ideas for better management.

The exhibits and models in this sub-theme may pertain to:

 

The spectacular industrial and economical development over the past few decades has led to the replacement of the communities of nature by man-made communities. Deforestation, overgrazing, indiscriminate mining, and tree-felling, faulty tillage practices etc. have led to severe soil erosion. Over irrigation and river-harvesting of agricultural lands has resulted into salinity of water, water logging and degradation. Over-use of tube wells has substantially lowered down the underground water table. Major current environmental issues include climate change, species extinction, pollution, environmental degradation, and resource depletion etc.

For humans to live sustainably, the Earth's resources must be used at a rate at which they can be replenished. The main objective of this sub-theme is to make general public and children in particular aware with the current environmental issues and concerns for achieving sustainability to prevent the effect of environmental issues.

The models and exhibits in this sub-theme may pertain to:

Mathematics and Everyday life

The important segment of mathematics-- the ability to reason and think clearly, is extremely useful in our everyday life. Proofs and deductions are hallmarks of mathematics. The subject also deals with data, measurements and observations from science, mathematical models of natural phenomenon including human behaviour and social systems. Its domain is not molecules or cells but numbers, chance, forms, pattern and order, algorithms and change. As a science of abstract objects, mathematics relies on logic rather than on observation.

Mathematics gives an exactness in thinking and provides a quantitative approach. The special role of mathematics in education is a consequence of its universal applicability. In general, to solve practical problems we follow a set procedure involving steps related with defining variables; writing equations or inequalities; collecting data and organize into tables; making graphs and illustrations; and calculating probabilities.

To encourage and stimulate students' interest in Mathematics, some of the mathematical principles being transacted at school stages with their applications have been indicated below.

Subtheme-6                                       Disaster Management

Disasters have significant relationship with natural resource management, poverty allevaiation and sustainable development. Various disasters can cause damage to human life, environment, infrastructure, lowering the quality of life, loss of different bio organisms, political instability and conflicts, demographic imbalance, unemployment etc.

Sub-theme-5

7

There is chaos and disorganisation in the event of any natural or manmade disaster. The objective of this sub-theme is to increase awareness of the dangers posed by disasters and to help children find measures for effective mitigation of those dangers.
