  • 11. PARTNER IN EXCELLENCE BAL BHARTI PUBLIC SCHOOL DWARKA 11 "Let noble thoughts come to us from all sides" "Astronomy is useful because it raises us above ourselves; it is useful because it is grand; …. It shows us how small is man's body, how great his mind, since his intelligence can embrace the whole of this dazzling immensity, where his body is only an obscure point, and enjoy its silent harmony“ Henri Poincaré, Physicist At Bal Bharati Public School, it is our constant endeavor to ensure that the students are enriched with the innovative methods of scientific learning and achieve the sense of accomplishment as epitomised in the space programme. The school joined hands with SPACE Club to take the students through a challenging week long explorations and joys of learning through participation in a plethora of events under the ambit of Astronomy Day held on 17th August,2013 to celebrate the significance and relevance of innovations in the field of astronomy. The occasion which witnessed enthused participation of students and teachers was the culmination and testimony of the year long coherent learning at Astronomy Club, conducted by SPACE.
  • 12. 12 The event featured challenging and interesting activities as ‘Rocket Launching”, ”Kit Display”, “Stellarium” and “Comet Kitchen”, a novel way of designing models of comets using items of daily use. Themed ‘tattoo making’ was yet another activity which the students enjoyed. It was exhilarating to witness the teachers too, participate in events as “The Solar Walk” and “Astronomy Quiz”. Ms. Suruchi Gandhi The Space Coordinator Ms. P. Gayatri, reiterated the pioneering initiative of the Astronomy Club and felt a sense of immense achievement as the students got an unparalleled opportunity to exhibit the scientific prowess acquired through the yearlong Space Learning. It was enlivening to observe the students intrigued and fascinated by astronomy. STUDENT SPEAK ‘It was a pleasant experience to practically showcase the knowledge acquired at SPACE Club Learning. It was particularly fun to participate in events as “Rocket Launching” and “Comet Kitchen”, where we could perceive models designed by us functioning in real life. On the behalf of the students, I would like to sincerely thank Ms. Sakshi Sharma and Mr. Rishabh Jain for imparting hands on expertise and training.’ Contribution by: BBPS Dwarka Team In the words of our school Principal, Ms Suruchi Gandhi ‘The event comprising an array of enrichment sessions served to unleash scientific creativity and visit untouched vistas of experience’.

  • 15. COVER STORY - 30 Years Ago: First African-American Launches into Space 15 Thirty years ago on August 30, Guion "Guy" Bluford became the first African American in space, launching into low-Earth orbit aboard the Space Shuttle Challenger on the mission STS-8. But he never set out to be a pioneer. Dr. Guion Stewart “Guy” Bluford, born on November 22, 1942, a NASA astronaut was a Colonel in the U.S. Air Force. He participated in four Space Shuttle flights between 1983 and 1992. "My desire," says Bluford, "was to make a contribution to the program.“ Years later, Bluford still recalls the rain-soaked, early Florida morning of Aug. 30, 1983, when a crowd of VIPs and other soggy well-wishers at the Kennedy Space Center awaited Space Shuttle Challenger's soar into history on STS-8. "People came from all over to watch this launch because I was flying," said Bluford, recalling his thoughts while strapped in and awaiting Challenger's dramatic liftoff. "I imagined them, all standing out there at one o'clock in the morning with their umbrellas, all asking the same question, 'Why am I standing here?'“ Dr. Guion Bluford
  • 16. 16 Bluford, one of three African- Americans in that 1978 barrier- breaking class of astronauts (former NASA Deputy Administrator Fred Gregory and Challenger astronaut, the late Ron McNair, the others), believes he was selected for the history- making mission because of his complement of pilot and engineering experience. "All of us knew that one of us would eventually step into that role...I probably told people that I would probably prefer not being in that role...because I figured being the No. 2 guy would probably be a lot more fun." Regardless, Bluford says he had plenty of fun as he and his four crew members successfully completed their mission. Astronaut candidates – Ronald McNair, Guion Bluford and Frederick Gregory
  • 17. 17 "The crew taped the intercom conversation," says Bluford of Challenger's liftoff, an experience they replayed upon their safe return to Earth. "There's somebody giggling and laughing all the way up. And we listened to it for quite a while to try and figure out who that was, only to come to the conclusion that it was me. I mean, I laughed and giggled all the way up. It was such a fun ride." Bluford says it took him awhile to recognize the historical significance of his selection to be the first African-American in space. But when his pioneering role became apparent, Bluford says he embraced it. "I wanted to set the standard, do the best job possible so that other people would be comfortable with African- Americans flying in space and African-Americans would be proud of being participants in the space program and… encourage others to do the same.“ Guy Bluford on STS-8.
  • 18. 18 Answer: While walking down the street on a sunny day, you must have observed something black following you every moment. The black thing is known as a “SHADOW” which is formed when direct light from a light source cannot reach on the surface due to obstruction by an object as shown in fig1. Shadow can be classified in two categories i.e. Umbra (Dark shadow) and Penumbra (Light shadow) which depends on the source of light. Let’s see how umbra and penumbra form. When all the light from the light source is blocked by an object, it results in the formation of a dark shadow known as Umbra. When light from one source is blocked with light from another source filling in some of the shadow OR when a large light source is only partially blocked, it results in the formation of lighter shadow known as penumbra. Fig. 1 Q. WHY SHADOW HAS TWO PARTS – UMBRA AND PENUMBRA?

  • 20. ARTICLE - Eratosthenes: Beta (Second best) of the Ancient World 20 There was once a time when our little planet seemed immense, it was the only world that could be explored. Its true size was first worked out in a simple and ingenious way by a man who lived in Alexandria in the 3rd Century B.C.: Eratosthenes. Eratosthenes was a man with many talents! An astronomer, a historian, a geographer, a philosopher, a poet, a theatre critic, a mathematician and The Chief librarian of Great Library of Alexandria. One day while reading a papyrus book in the Great Library, he came across a curious account: Far to the south in a place called Syene something notable could be seen on the longest day of the year. On June 21st, the shadow of temple column or a vertical stick would grow shorter as noon approached. And then precisely at noon, columns would cast no shadow and at that moment the sun was exactly overhead. It was an observation which someone might have easily ignored- sticks, shadows, position of sun. Simple everyday matters what possible importance might there be?! But Eratosthenes was a scientist and his perception on this matter changed the whole world in a way lead the world because Eratosthenes had the presence of mind to experiment and to actually ask that whether a stick in Alexandria would cast a shadow in noon of June 21st and as it turns out it did!
  • 21. 21 Eratosthenes asked himself that how in the same moment a stick in Syene would cast no shadow while a stick in Alexandria 800 meters away north would cast a shadow. Eratosthenes probed further to find out that two sticks in a flat surface would cast a shadow of same length but if a flat surface was curved than the shadow length of the two sticks on that curved surface would change. This minor but very important observation led to the conclusion that the earth is infact curved and not a flat surface which resulted in the change in shadow length of two sticks in two different places on Earth, bigger the curvature bigger the difference in the length of the shadow. Artistic impression of Great Library of Alexandria Temple Columns at Syene
  • 22. 22 The sun is so far away, the rays are parallel when they reach the earth, sticks at different angles would cast a shadow of different length. The observed difference in the shadow length, the distance between Alexandria and Syene had to be about 7 degrees along the surface of the earth (if we extended the sticks in Alexandria and Syene towards the centre of the earth, they will intersect at an angle of 7 degrees). Eratosthenes hired out a man to walk from Alexandria to Syene to measure the distance in steps between the two places which was found out to be 5000 stades (approx 800 metres). He then put the values in the simple formula: Ɵ/d = 360/ C Ɵ = 7 degree (the angle formed when the two sticks were extended towards the centre of the Earth) D = 800 metres (Distance between Syene and Alexandria) C = Circumference Of the Earth Eratosthenes calculated the circumference of the Earth as 40000 kms. Eratosthenes only tool was sticks, eyes, brains and feet plus a zest for experiment. With these tools he correctly deduced the circumference of Earth to high precision with error of only few percent. That is pretty good figure for 2300 years ago!!!! Besides calculating the circumference of Earth, Eratosthenes invented a system of latitude and longitude, calculated the tilt of the earth's axis, may also have accurately calculated the distance from the earth to the sun and invented the leap day, created a map of the world based on the available geographical knowledge of the era, coined the term ‘geography’
  • 23. 23 Eratosthenes was also the founder of scientific chronology; he wanted to fix the dates of the chief literary and political events from the conquest of Troy. Every year SPACE tries to find out modern day Eratosthenes by taking the PROJECT PARIDHI to school students and normal masses four times a year. The four times are the four special days of the year which are called as the Spring Equinox (22nd March), Summer Solstice (21st June), Autumnal Equinox (22nd September), and Winter Solstice (21st December). On these days, our students conducts the same experiment that Eratosthenes did 2300 years ago to calculate the circumference of the Earth, helping the students to understand the concept and how a scientific temperament of observation and questioning can lead to a whole world of discoveries! Since the introduction of Project Paridhi in the summer of 2011, thousand of students have done the experiment in various well known locations of Delhi such as Jantar Mantar, Qutub Minar, Barapullah and various school locations. For the upcoming September Equinox we will be adding India Gate as one more location where the experiment will be conducted.

  • 24. ASTRONOMY AT HOME – Spinning Balloon 24 Through this activity, we are going to learn the Newton’s third law of motion i.e. Action and Reaction. 1. Bendable Straw 2. Old ball pen refill 3. Rubber band 4. Balloon 5. Paper pin
  • 25. 25 Stepwise Procedure: 1. Take a bendable straw, bend it 90◦ from the bendable part and poke a paper pin at its center 2. Now tie the balloon on the right end of the straw with the help of a rubber band properly so that air cannot escape through the opening.
  • 26. 26 3. After that place the paper pin in the old ball pen refill which will act as a bearing and help in holding the straw. 4. After preparing the spinning balloon blow air in the balloon from straw and hold the opening of the straw so that air cannot come out.
  • 27. 27 5. Now, do a countdown and leave the open end of the straw. You will see that straw will start spinning. The straw will spin because the air from the balloon will come out with a great pressure, pushing the open end of the straw to the opposite side. Here, the action is air coming out of the balloon and the reaction is motion of straw in opposite direction.
