The Central Board of Secondary Education has been taking many initiatives to provide interactive, participatory, hands-on, innovative and creative learning experiences to students studying in its affiliated schools. One such initiative refers to the organisation of Science Exhibitions at Regional and National levels every year. The activity aims at providing a common platform to schools, teachers and students to give shape to their innovate ideas and learn from each other’s experiences. These exhibitions also intend to provide a medium for popularising Science and increase awareness among the stakeholders about close relationship between Science, Technology and Society. The main objectives of organising Science exhibitions can be summarised as:

• promoting interest in Science and Technology among younger generation.
• encouraging scientific and technological creativity among students and inculcating a sense of pride in their talent.
• providing exploratory experiences, encouraging creative thinking and promoting psychomotor skills among school students through self designed models or simple apparatus.
• encouraging problem solving approach and developing appropriate technologies, especially for rural areas and integrating scientific ideas with daily life situations.
• popularising Science and technology among masses and creating an awareness regarding its impact on socio-economic and sustainable development of the country.

Guidelines for preparation of Exhibits and Models

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:

• Studies of climatic change on agriculture
• Managing crop yield due to climatic change arising from global warming
• Preservation and conservation of soil and judicious use of water
• Conventional biotechnology practices e.g., application of biotechnology, microbiology, genetic engineering and genomics to agriculture for improved and high yielding varieties
• Organic farming/organic fertilisers versus chemical fertilisers; biodynamic liquid manure/green manure
• Use of biotechnology for economically and ecologically sustainable biofuels
• Environmental friendly measures of pest control
• Application of biotechnology and genetic engineering in improving animal breeds and production of animal products that are used as food
• Innovative/inexpensive/improved/indigenous technologies/methods of storage/ preservation /conservation/transport of agricultural products and food materials
• Organic fertilizers versus chemical fertilizers
• Food production and demand of quality food and food security
• Nutrition education/healthy eating habits and food utilisation by body

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.

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

• Models of green building/environment building which harvest energy, water and materials
• Green roof technologies/roof mounted solar technologies such as solar water heater, solar lighting system
• Models/innovative designs of domestic hydroelectric generator
• Solar cooker/solar distiller/solar dryer for food processing/solar heated houses
• Studies of variation in sunshine intensity at a given place for developing indigenous method of its usage etc
• Projects for measuring availability of solar/wind energy in a given area
• Use of tidal waves/ocean currents/salinity gradient for generating electricity
• Energy from biomass such as seaweeds, human/animal wastes, keeping in view environmental concerns
• Improvised technologies for effective usage of bio-fuels
• Innovative designs of bio gas/bio mass plant
• Bio diesel from plant oils (obtained from canola, palm oil, micro algae oil, waste, vegetable oil etc)
• Low cost liquid fuel (bio-ethanol, bio methanol from cellulose biomass by improvising conversion techniques)
• Innovative designs of internal combustion engine which can function on various bio fuels
• Production of electrical energy from mechanical energy/nuclear resources

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:

• Demonstration of health and differentiation from the state of ill health
• Sensitising people to be careful in health matters, explore the possibilities and make use of the facilities available
• Development of knowledge-base and understand new scientific, technological aids in bio­medical area
• Demonstration of known facts and research findings in different medical systems like Indian, Modern, Homeopath etc.
• Demonstration of lifestyle and relationship with good and bad health based on known facts and researches
• Need for appropriate measures for family welfare
• Need for developing low-cost nutritious food
• General awareness about occupational hazards and innovative techniques to overcome them
• General awareness about community medicine
• Simple technologies for developing diagnostics and environmental monitoring. Sub theme-4          Environmental Issues and Concerns

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:

• Environmental issues related with human activities such as agriculture, energy, fishing, forests, mining, shipping, paper, war, ocean deoxygenation, dead zone, paint etc.;
• Environmental issues with energy conservation, renewable energy, efficient energy use, renewable energy commercialization etc;
• Environmental controversies such as dam controversies, genetically modified organisms/food controversy, sealing, dioxin controversy, water fluoridation controversy etc.;
• Environmental disasters such as Bhopal disaster, oil spills, nuclear accidents etc.
• Climate change — global warming, greenhouse gases, fossil fuels, sea level rise, ocean acidification etc.;
• Issues related with environmental health such as air quality, asthma, electromagnetic radiations and fields, lead poisoning, indoor air quality, sick building syndrome etc;
• Water pollution — acid rain, marine pollution, Ocean dumping, eutrophication, marine debris, thermal pollution, algal boom, micro-plastics, etc;
• Air pollution — smog, ozone, particulate matter, sulphur oxide etc;
• Soil erosion, soil contamination and salination and Waste;
