In this year 2020 will be 17th IJSO organized. India has been also taking a part in these Olympiads and we have several rounds in India as well. This is the most prestigious exam in science.

IJSO exam is eligible for students those who came under the Age category for 15 years. Main to conduct this examination to promote interest in science among school students exposing them to problem-solving critical thinking and experimentation.

The overall motive is to encourage the students for science and mathematics education at the school level. This exam will motivate students for critical thinking and increase their interest in Science subjects. IJSO exam held in the first week of December of every year in different countries.

An important part of this Olympiad most experience peoples from different countries will interact with the students. IJSO exam has conducted in a very organized way every year.

There are 5 stages in IJSO 2020 details as bellow.

Stage 1: National Standard Examination in Junior Science (NSEJS)

NSEJS examination is organized by the Indian Association of Physics Teachers (IAPT). This examination has conducted for the student selection purpose for the Junior Science Olympiad Program (next level). The top 300 qualify for the next round.

Stage 2: Indian National Junior Science Olympiad (INJSO)

This exam will be organized by HBCSE at about 15 centers in the country.  The syllabus is similar to NSEJS and the top 35 will qualify for the next level (OCSC).

Stage 3: Orientation cum Selection Camp (OCSC) in Junior Science

This examination will be organized by HBCSE for 2-3 weeks. In this level, those students are eligible only who are in the merit list in the 2nd (Stage 2) level. There will be no other criteria or provisions. The camps include several theoretical and experimental tests.

Stage 4: Pre-departure Training Camp (PDT)

In this stage, 6 students will be selected for the final round. Which is conducted by HBCSE in theory and experiment?

Stage 5: Participation in International Junior Science Olympiad (IJSO)

International Junior Science Olympiad (IJSO) examination is the final round of the all over the program. Selected all the students will constitute the delegation to represent India at the International Junior Science Olympiad (IJSO).

Note: Stage 1 will be conducted by IAPT and the rest of the stages will be organized by HBCSE (Homi Bhabha Centre for Science Education).

Syllabus for the IJSO 2020

1. Particles, waves, and matter

The matter is structured from the smallest particle to the size of the universe. The microscopic structure of matter is responsible for the features we observe macroscopically. The students should be aware of this structure and be familiar with the following concepts:

What things are made of

Periodic table - concept, organization, and structure

States of matter and its properties


  • Frequency, wavelength, speed of propagation and its relation
  • Difference between transversal and longitudinal waves
  • Superposition of waves
  • Classical Doppler effect



2. Energy

  • Nature of energy and energy conservation
  • Various forms of energy

(bonding energy, kinetic energy, potential energy, heat, activation energy, energy stored in the spring)

  • Transfer of energy

(e.g. mechanisms of heat transfer, transfer of energy via waves)

  • Energy conversion/transformation and its efficiency

(e.g. conversion between potential and kinetic energy, bonding energy and temperature or the loss of energy to the environment by radiation)

  • Sources of energy

(e.g. for animals, plants, societies, and engines. Fossil and renewable energy sources)

  • Power

(e.g. muscular power, power output of engines or stars, power dissipation in resistors)

3. Interactions

  • Forces
  • Electric, magnetic and gravitational fields
  • Type of chemical bonding - nature, structure and strength
  • (covalent and ionic bonds, hydrogen bonding and van-der-Waals interaction)
  • Chemical Reactions
  • Diffusion, osmosis and surface tension
  • Principle of thin layer and paper chromatography
  • Effects of radiation on organisms
  • Forms of communication

4. Structure, properties and functions

  • Cells
  • Parts of the body
  • Homogeneous and heterogeneous catalysts
  • Acids and bases

5. Systems

  • Continuity principles in closed systems/cycles
  • Equilibriums
  • Scales of nature
  • Basic concepts about cycles in nature
  • Ecology
  • Pollution effects of different modes of power generation
  • Organisms as systems
  • Plant physiology
  • Electric Circuits
  • Thermodynamical systems
  • Astrophysical systems

6. Development and Evolution

  • Strategies of environmental adaptation
  • Theory of evolution
  • Cell cycle and cell division
  • Reproduction in humans, animals and plants
  • Genes, chromosomes and genetics
  • Diseases

7. Mathematics skills

  • equations involving
