National Science Olympiad – NSO 2017

NSO 2017

The Science Olympiad Foundation, a non profit educational organisation conducts the National Science Olympiad or NSO annually to promote young minds in the discipline of science. The NSO identifies the talents and assesses the students on the basis of their understanding of scientific fundamentals and concepts. This Olympiad is considered as one of the most prestigious examinations held in Asia.

National Science Olympiad Eligibility:

Students from class 1st to 12th  are eligible to participate in the Olympiad. The prospectus, registration forms, posters and other details relevant to the event are sent by the Science Olympiad Foundation to the schools registered with the NSO.

National Science Olympiad Selection Procedure:

The selection process for NSO comprises of examinations held at two levels:

A. Level 1 is organized at the school level. Participants take the test at their respective schools during the school hours.

B. Level 2 is organized for the participants who qualify the first level of examination.

The eligibility criteria for the same is either of the following:

A. Classwise top 5% of students, who appeared for the 1st level of the examination.

B. Zone wise or State wise top 25 rank holders from each class.

C. Class topper, where at least 10 students from a class appear in the examination and scores at least 50% marks.

National Science Olympiad Examination Pattern:

Exam Duration: 60 Minutes and Paper Pattern: MCQ patterned test.

The question paper is different for each class. The syllabus of the Olympiad is same as prescribed by the CBSE, ICSE and various state boards.

National Science Olympiad Results & Ranking:

The performance of a participant is gauged on the basis of his individual score compiled in a Student Performance Report (SPR). The SPR provides a detailed analysis of strengths and weaknesses of a student as the Science Quotient (SQ) evaluation along with a performance comparison at the school, state, and national level. On the basis of ranks secured in Level 1, the students would be eligible to appear for the 2nd level NSO Exam.

Scholarships:

Students are generously awarded on the basis of their ranking. Prizes are announced annually including medals, cash prizes, awards, gifts, certificates and more. Medals and Merit Certificates are awarded to the highest ranked participants. The participation Certificates are provided to every student.

Important Dates:

NSO examinations are generally conducted in the month of November and the registration for the same closes by the August end.

A. 1st level of NSO exam will be conducted on 9th & 23rd November 2017.

B. 2nd level of NSO exam would be conducted in February 2018 (either 2nd or 3rd Sunday).

NSO not only looks for intellectual students but it also ensures, through its testing methods, that the students qualifying the NSO are the best brain on the planet- it looks for the prodigies.


Practise This Question

Fractional distillation is the separation of a mixture into its component parts or fractions. This is the process of separation of chemical compounds due to difference in their boiling point. The mixture is heated to a temperature at which one or more fractions (component parts) will vaporize. It is a special type of distillation.

Air is a homogeneous mixture of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases such as helium, krypton, nitrogen dioxide etc.

Consider three gases oxygen, nitrogen and argon whose boiling points are -183, -196, -186 degree celsius, they are to be separated from air using fractional distillation.

Air is compressed by increasing the pressure and then cooled by decreasing the temperature in order to get liquid air. This liquid air is allowed to warm-up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points. As the height of tower increases the temperature increases.

Statement: The temperature is ____ at the base of the fractional distillation column.
