National Children’s Science Congress (NCSC) 2026–27

Theme: Science and Innovation for Sustainability

Introduction

In the modern era, science and technology have transformed human life in extraordinary ways. From space exploration to artificial intelligence, humanity has achieved remarkable progress. However, this rapid development has also led to serious global challenges such as environmental degradation, climate change, water scarcity, pollution, and loss of biodiversity.

To address these challenges and nurture scientific thinking among young minds, the Government of India, through the Department of Science and Technology, organizes the National Children’s Science Congress (NCSC). This program serves as a powerful platform for students to explore real-life problems and develop scientific solutions.

What is the National Children’s Science Congress (NCSC)?

The National Children’s Science Congress (NCSC) is a nationwide program designed for students from classes 6 to 12. It encourages children to move beyond textbook learning and engage in practical, research-based problem-solving.

Key Objectives:

• To develop scientific temperament among children
• To promote research-based learning
• To encourage innovation and creativity
• To identify and solve local problems using scientific methods

The program is conducted at three levels:

1. District Level
2. State Level
3. National Level

Theme of NCSC 2026–27

“Science and Innovation for Sustainability”

This theme reflects one of the most urgent needs of our time. It focuses on:

• Balanced use of natural resources
• Environmental protection
• Ensuring a sustainable future for upcoming generations

Sustainability means meeting present needs without compromising the ability of future generations to meet their own needs.

Importance of Mission LiFE

The theme aligns with India’s Mission LiFE (Lifestyle for Environment) initiative.

Objectives of Mission LiFE:

• Promote environmentally responsible behavior
• Encourage sustainable lifestyle choices
• Build harmony between humans and nature

Examples of Sustainable Practices:

• Reducing plastic usage
• Saving electricity
• Conserving water
• Using public transport or bicycles

Mission LiFE emphasizes that small individual actions can collectively create a large global impact.

Current Environmental Challenges

According to the guidebook, Earth is facing several critical issues:

• Deforestation
• Pollution
• Climate change
• Melting glaciers
• Rising sea levels

These warning signs highlight the urgent need for immediate action.

Sub-Themes of NCSC 2026–27

1. R5 for Waste Management

(Reduce, Reuse, Retrieve, Redesign, Recycle)

Waste management has become a major global concern. A large portion of waste generated is not properly processed.

The R5 Principles:

1. Reduce

Minimize consumption and avoid unnecessary use of materials.

2. Reuse

Use items multiple times instead of discarding them.

3. Retrieve

Recover useful materials or energy from waste.

4. Redesign

Develop products that generate less waste and last longer.

5. Recycle

Convert waste materials into new usable products.

Example Project: E-Waste Management

Electronic waste contains valuable metals such as:

• Gold
• Copper
• Lithium

Benefits:

• Reduces environmental pollution
• Saves natural resources
• Supports economic growth

2. E4 for Energy

(Explore, Experiment, Enhance, Evolve)

Energy is essential for modern life, but traditional sources like fossil fuels harm the environment.

E4 Model:

1. Explore

Understand different forms of energy.

2. Experiment

Conduct practical experiments like solar cookers or windmills.

3. Enhance

Improve energy efficiency.

4. Evolve

Adopt sustainable and green technologies.

Examples:

• Solar panels
• LED vs traditional bulbs
• Biogas systems

3. Water Management

(Harvesting, Harnessing, Recycling, Conservation)

Water is essential for life, yet water scarcity is increasing globally.

Key Approaches:

1. Harvesting

Collect and store rainwater.

2. Harnessing

Use water efficiently.

3. Recycling

Reuse wastewater.

4. Conservation

Reduce water wastage.

Example Project: Water Audit

Steps:

• Measure daily water usage
• Identify wastage points
• Suggest conservation methods

Outcome:

• Awareness and reduction in water usage

4. Food, Agriculture & Health

Food is directly linked to human health.

Key Concepts:

• Organic farming

2. Wetland Filtration System

Process:

• Use aquatic plants to purify wastewater

Benefits:

• Natural purification
• Cost-effective
• Eco-friendly

How to Conduct a Research Project

Steps:

1. Identify a problem
2. Form a hypothesis
3. Collect data
4. Analyze results
5. Draw conclusions

How to Present a Project

• Speak clearly and confidently
• Use charts, graphs, and models
• Present data logically
• Answer questions effectively

Role of Students
