Science
Kids

Kids are always enthusiastic and ask questions and doubts in a never ending mode. But many questions remain unanswered and they forget even the questions they asked as they grow up.

The satisfactorily answered questions add to their knowledge. So, giving answers to the questions and doubts of young kids is the main concern here.

On Dance: A Physics Lesson

2010-06-05T14:32:00.001+05:30

Erotic is not a word usually associated with physics, but that is one of the ways Karole Armitage describes the complicated subject she explores in her new work “Three Theories.” The choreographer has created the piece, which takes on relativity, quantum mechanics and string theory as part of the 2010 World Science Festival this week in New York. We asked Ms. Armitage about science, its relationship to dance, and the influence of her father, a biologist, on her work. “Three Theories” will have its New York premiere on Thursday night at Cedar Lake Theater in Chelsea; it runs through Sunday.

CBSE issues guidelines for standard 11 admissions

2010-06-05T14:29:00.000+05:30

Against the backdrop of the newly introduced nine-point grading system in its class 10 examinations, the Central Board of Secondary Education (CBSE) has issued a set of guidelines to schools affiliated to it to be followed for admissions to standard 11.

In a circular issued on Friday, the CBSE suggested the determination of inter-se merit of candidates, based on the calculation of indicative percentage of marks, for the preparation of the admission list. The circular is available on the web site www.cbse.nic.in. Detailed circulars on the grading system and on continuous and comprehensive evaluation can also be obtained from the web site.

The indicative percentage of marks obtained by a candidate can be determined by multiplying the cumulative grade point average (CGPA) by 9.5. Similarly, subject-wise indicative percentage of marks can be determined by multiplying the grade point (GP) for that subject by 9.5.

The circular says that in case of a tie in the CGPA between two or more candidates, the average subject-wise indicative percentage of marks obtained by the candidates in one compulsory language and the subjects they opt for studies in the higher secondary class should be taken into consideration. However, the circular also says that schools can adopt other methods that they find suitable in their own context.

The CBSE had directed schools to introduce a nine-point grading system in classes IX and X from the second half of the academic year 2009-10, along with the introduction of continuous and comprehensive evaluation.

In the nine-point grading system, the student's performance is first assessed using conventional numerical marking mode and then converted into grades on the basis of pre-determined mark ranges as stipulated by the CBSE.

Although the examination reforms and the evaluation methods introduced by the CBSE have been generally welcomed by teachers, parents and students, the new system did give rise to doubts and confusion in its first year of implementation. Misconceptions such as equating the CGPA to total percentage of marks achieved by a student and determination of school toppers based on these figures continue to prevail in some quarters.

“There is a general perception that a CGPA of 9.8 is equivalent to 98 per cent mark or likewise a CGPA of 10 is equal to 100 per cent marks. This is wrong and you cannot determine a school topper based on this calculation,” said K.O. Ratnakaran, Principal, Jawahar Navodaya Vidyalala, Chettachal. The main objective of the system is to discourage unhealthy competition and practices such as determining school toppers, number of distinctions and first classes, he pointed out.

NCERT clash with CBSE on new syllabus

2010-06-05T14:14:00.000+05:30

The National Council of Education Research and Training (NCERT) has taken strong exception to the Council of Boards of School Education in India (COBSE) and the Central Board of Secondary Education (CBSE) developing a common curriculum in science and mathematics.

Describing the task as its responsibility, the NCERT has asked COBSE, which comprises representatives of all state boards, and the CBSE to keep off its turf.

In its last meeting, COBSE had claimed that all state boards had agreed on having a common syllabusin science and maths and they would be working together to develop it. The NCERT's acting director, G. Ravindra, said he had written to the CBSE. "According to the National Policy on Education, framing a national curriculum is the NCERT's responsibility. It is not the job of COBSE or the CBSE," he said.

Ravindra said the NCERT had already framed the National Curriculum Framework (NCF) in 2005. "This has taken care of a common curriculum in science and maths. The NCERT has to review the curriculum every five years.

But the CBSE's job is restricted to conducting exams and implementing examination reforms, not framing curricula," he said. The CBSE and COBSE had written to the NCERT, asking it to "participate" in the process of framing a common curriculum. This led to the NCERT's objection.

The NCERT is also sceptical about COBSE's claims of a " consensus" among all the state boards on the issue.

According to the NCERT, only 18 states have accepted the common syllabus. West Bengal and Uttar Pradesh, among others, are opposed to it.

After the COBSE meeting in February, Union human resource development minister Kapil Sibal had announced that from the academic year 2011- 12, the science and mathematics curricula for classes XI and XII would be uniform across the country, claiming that a " consensus" had been reached on the issue.

Sibal had even said after science and maths, COBSE would start framing a common commerce curriculum.

This makes the development interesting because as the HRD minister, Sibal is also the NCERT president. Now on loggerheads with COBSE and the CBSE, the NCERT has chosen to take a stand contrary to the minister's.

The NCERT says the NCF curriculum it had framed in 2005 has been accepted and implemented by 14 states.

COBSE general secretary professor D. V. Sharma has said the school boards have every right to update their syllabus. The boards had asked COBSE to take up the revision and then it was carried out. " The NCERT's opposition is unnecessary.

The NCERT had sent a representative to the consultation programme on the common curriculum," he said.

CBSE Chennai region scales a 20-year high

2010-06-02T09:17:00.003+05:30

CHENNAI: On Friday, when the Central Board of Secondary Education (CBSE) declared the results of the All-India Secondary School Examination (class X), awarding grades to students instead of marks, it was time for a triple celebration for schools in the Chennai region.

First, the students were relieved of the tensions usually associated with the mark-based valuation system where a single mark can make or mar one’s future . Second, students of the Chennai region, comprising the southern states, Maharashtra, Goa and the four union territories , scaled a 20-year high in overall success rate. Of the 1,16,927 candidates from the region who appeared in the AISSE, 96.18% were successful, enveloping last year’s record of 95.6%. Add to this the fact that just a week ago, class XII students of the Chennai region set a 16-year record in overall pass percentage.

Incidentally, both the class X and class XII students of the region had set new records in pass percentage just last year, which has been erased now.

The CBSE has not classified students as “passed” , “failed” or “compartmental candidates ” this year. “We are declaring a unique result where candidates who have secured grades D to A1 are declared as ‘qualified’ for higher studies and those with grades E1 and E2 are classified as ‘EIOP’ meaning they are eligible for improvement of performance,” N Nagaraju, joint secretary, CBSE (Chennai region), said.

No failures in CBSE exams this year
CHENNAI: The CBSE has not classified students as “passed” , “failed” or “compartmental candidates” this year. Candidates who have secured grades D to A1 are declared as ‘qualified ’ for higher studies and those with grades E1 and E2 are classified as ‘EIOP’ meaning they are eligible for improvement of performance.

The EIOP candidates would be required to obtain a grade of D and above, utilising chances in July 2010, March 2011, July 2011, March 2012 and July 2012 to qualify for admission into class XI or for higher studies.

Nagaraju, joint secretary, CBSE (Chennai region), said students securing marks between 91 and 100 would be awarded ‘A1’, which entitles them to a grade point of 10. A student scoring between 33 and 40 marks will be awarded ‘D’ , with a grade point of 4.

While such grades and grade points are awarded for each subject, a cumulative grade point average (CGPA) will be calculated for each student by adding the grades of all five subjects and dividing it by 5. Once this figure is arrived at, an overall indicative percentage of marks will be calculated by multiplying the CGPA with 9.5 through a standard deviation method to enable preparing the merit list for admission in Class 11.

“We have already instructed all school principals on calculating the overall indicative CGPA,” Nagaraju said.

Kapil Sibal launches CBSE- intrnational curriculum in Dubai

2010-05-28T13:37:00.000+05:30

The Central Board of Secondary Education (CBSE) on Tuesday launched its self-designed international curriculum that aims to compete with its western counterparts to produce the global citizen of tomorrow.

Human Resource Development Minister Kapil Sibal presided over the worldwide launch of the CBSE-international (CBSE-i) curriculum at Dubai's Indian High School (IHS). The IHS will also become a global centre for training teachers in the new curriculum under the guidelines of the CBSE.

The Minister said that CBSE's initiative was futuristic, and was a reflection of India's ambitious drive to establish a vast pool of skilled manpower that could become a significant driver of the global economy.

“It is important to realise that the global community is going to need quality human resources. That will be provided only by countries where human resources are available,” Mr. Sibal said in a conversation with The Hindu. Because of its ample pool of young people, India has the advantage of having a “demographic dividend” in comparison to A “demographic deficit” that was being felt in the rest of the world, he said.

Elaborating on the new initiative, CBSE Chairman Vineet Joshi said learning skills apart, the CBSE-i would also impart to its students social skills, and at the same time highlight the importance of a positive attitude. “Having the right attitude, willingness to learn and an ability to work in teams will be given prime importance, as demanded by the globalised world.”

Visual and performing arts

The new curriculum, which is being introduced in nine countries and 39 schools, would also give substantial importance to visual and performing arts. Social science, math, and the sciences would be taught in a “globally sensitive manner,” Mr. Joshi said.

Mr. Sibal later explained at a press conference that the CBSE-i has been geared to compete well with Switzerland’s International Baccalaureate (IB) system and the International General Certificate of secondary Education (IGCSE) offered by Britain’s Cambridge University.

He pointed out that his ministry had brainstormed some possible solutions to meet the heavy expenditure that would have to be incurred to fulfill his plan of establishing 700 new universities and 35,000 colleges by 2020. “We decided to investigate the possibility of setting up an Education Finance Corporation (EFC), which at present is at a conceptual stage. We had a discussion with the planning commission and they are in agreement with the idea.”

The visiting minister said the EFC would serve two purposes. First, it would make it easier for investors to avail low interest credit, provided education in the near future is officially designated as a “priority sector”. Second, students seeking expensive professional degrees in fields such as medicine, engineering or management, would be entitled to government-guaranteed concessional loans. By implementing some of its new plans, the ministry hopes to raise the intake of high school graduates into the higher education stream by 30 per cent from the present 12.4 per cent.

For many of those who are left behind, a revamped vocational educational system, where foreign investors are likely to play a prominent part is in the pipeline. Mr. Sibal later participated in a ground-breaking ceremony of Manipal University’s new campus at Dubai’s International Academic City.

CBSE class 10 results out

2010-05-28T13:32:00.000+05:30

The Central Board of Secondary Education (CBSE) on Friday declared the results of the Class 10 exam, held under the grading system for the first time.
"The result was declared at 10 a.m.," a CBSE spokesperson said.
Under the new grading system, the internal assessment marks of the students are added to the board examination scores and students get grades instead of percentages. The grades have been given on a nine point scale ranging from A1 (excellent) to E2 (dissatisfactory) with D being the minimum pass grade.
A1 represents above 91 score. Similarly, B1 is 81 to 90, while D is for marks from 33 to 40, and E1 and E2 are below 33. The grades also have equivalent points which start from 10 for A1 to 4 for D.
As the exact marks will not be revealed, these points can be multiplied with 9.5 to get the average marks represented by the grades. Thus, A1 will be equal to 95, A2 - 85.5, B1 - 76, B2 - 66.5, C1 - 57, C2 - 47.5 and D will be equal to 38 average marks.

The Diamond Ring Solar Eclipse

2010-01-15T10:35:00.000+05:30

Eye Safety During Solar Eclipses

2010-01-15T10:28:00.000+05:30

Visit the Nasa Site (http://eclipse.gsfc.nasa.gov) for more details

The Sun can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse. Partial eclipses, annular eclipses, and the partial phases of total eclipses are never safe to watch without taking special precautions. Even when 99% of the Sun's surface is obscured during the partial phases of a total eclipse, the remaining photospheric crescent is intensely bright and cannot be viewed safely without eye protection [Chou, 1981; Marsh, 1982]. Do not attempt to observe the partial or annular phases of any eclipse with the naked eye. Failure to use appropriate filtration may result in permanent eye damage or blindness!

Generally, the same equipment, techniques and precautions used to observe the Sun outside of eclipse are required for annular eclipses and the partial phases of total eclipses [Reynolds & Sweetsir, 1995; Pasachoff & Covington, 1993; Pasachoff & Menzel, 1992; Sherrod, 1981]. The safest and most inexpensive of these methods is by projection, in which a pinhole or small opening is used to cast the image of the Sun on a screen placed a half-meter or more beyond the opening. Projected images of the Sun may even be seen on the ground in the small openings created by interlacing fingers, or in the dappled sunlight beneath a leafy tree. Binoculars can also be used to project a magnified image of the Sun on a white card, but you must avoid the temptation of using these instruments for direct viewing.

The Sun can be viewed directly only when using filters specifically designed for this purpose. Such filters usually have a thin layer of aluminum, chromium or silver deposited on their surfaces that attenuates ultraviolet, visible, and infrared energy. One of the most widely available filters for safe solar viewing is a number 14 welder's glass, available through welding supply outlets. More recently, aluminized mylar has become a popular, inexpensive alternative. Mylar can easily be cut with scissors and adapted to any kind of box or viewing device. A number of sources for solar filters are listed below. No filter is safe to use with any optical device (i.e. - telescope, binoculars, etc.) unless it has been specifically designed for that purpose. Experienced amateur and professional astronomers may also use one or two layers of completely exposed and fully developed black-and-white film, provided the film contains a silver emulsion. Since all developed color films lack silver, they are always unsafe for use in solar viewing.

Unsafe filters include color film, some non-silver black and white film, medical x-ray films with images on them, smoked glass, photographic neutral density filters and polarizing filters. Solar filters designed to thread into eyepieces which are often sold with inexpensive telescopes are also dangerous. They should not be used for viewing the Sun at any time since they often crack from overheating. Do not experiment with other filters unless you are certain that they are safe. Damage to the eyes comes predominantly from invisible infrared wavelengths. The fact that the Sun appears dark in a filter or that you feel no discomfort does not guarantee that your eyes are safe. Avoid all unnecessary risks. Your local planetarium or amateur astronomy club is a good source for additional information.

In spite of these precautions, the total phase of an eclipse can and should be viewed without any filters whatsoever. The naked eye view of totality is completely safe and is overwhelmingly awe-inspiring!

Watching Solar Eclipse Safely

2010-01-15T10:23:00.000+05:30

The Pinhole Projection Method

One safe way of enjoying the Sun during a partial eclipse--or anytime--is a "pinhole camera," which allows you to view a projected image of the Sun. There are fancy pinhole cameras you can make out of cardboard boxes, but a perfectly adequate (and portable) version can be made out of two thin but stiff pieces of white cardboard. Punch a small clean pinhole in one piece of cardboard and let the sunlight fall through that hole onto the second piece of cardboard, which serves as a screen, held below it. An inverted image of the Sun is formed. To make the image larger, move the screen farther from the pinhole. To make the image brighter, move the screen closer to the pinhole. Do not make the pinhole wide or you will only have a shaft of sunlight rather than an image of the crescent Sun. Remember, this instrument is used with your back to the Sun. The sunlight passes over your shoulder, through the pinhole, and forms an image on the cardboard screen beneath it. Do not look through the pinhole at the Sun.
