Long Answer Type Question, (100-120 words):, Question 1. “Richard Ebright was, , a successful scientist who gave a, new theory of cells to the scientific, world”. Elucidate., , Answer: Richard Ebright conducted, an experiment on a flock of, butterflies and raised the eggs of, female monarchs. In addition to, , this, he also studied the cause of a, viral disease that killed all Monarch, caterpillars. He also tried to find, , out similarities between viceroy, butterflies and monarch. The study of, insect hormones helped him in giving, a new theory on the life of cells., Eventually, he was able to find the, hormone behind the full development, of a butterfly wings. All these, experiments led him to conclude that, cells grew from a monarch's wings., He found that cells would divide and, grow into a normal butterfly if they, were fed a hormone that was found, in the gold spots of the monarch., Hence, he proved a new theory which, formed the blue print of DNA. The, experiments conducted by Ebright, amply show him to be a successful

scientist., , Question 2. How did Ebright’s not, winning anything at the Science fair, motivate him to become a bright, scientist ?, , OR, , How did Ebright’s not winning, anything at the Science Fair motivate, him to become a bright scientist?, OR, , ‘Failure is the stepping stone to, success. Elucidate with reference, to Richard Ebright. [Value Based, Questions], , Answer: When Ebright was in the, seventh grade, he participated in a, country science fair and lost it. His, entry was Slides of frog tissues,, shown under a microscope. He felt, really sad when he just sat there, , and others won ‘many prizes. That, was the time of motivation. A sense, of real Science entered him and he, realised that winners had to try to, do real experiments and not just a, simple neat display. The competitive, spirit started entering him and he, thought of conducting experiments., Next year his experiment on Viceroy’s

copying Monarchs came first in the, zoology division and overall third., Next year he found out an unknown, insect hormone which led him to his, new theory on the life of cells. From, Ebright’s story, it is sufficiently clear, that defeat is the stepping stone of, success. Not winning anything at the, science fair encouraged him greatly, to conduct experiments., , Question 3. ‘Richard Ebright was, , a curious child, observing the, phenomena around him keenly, , and these traits contributed to, , his evolution into a scientist/ Do, you think such qualities should be, encouraged in children ? [Value, Based Questions], , Answer: Richard was an exceptional, child with rare qualities of intelligent, observation and keen interest in, , the nature of things.

These qualities are definitely, desirable in every child and the, curiosity should never be curbed, , or discouraged. Providing logical, answers to the queries goes a long, way to develop a scientific way

Q. 4. What are the values required, to become a successful scientist, like Richard Ebright? Elaborate with, reference to the lesson ‘The Making, of a Scientist’., , Answer: Curiosity to know more, and a motivation to find reasons, for existence of anything or any, phenomena are necessary for, becoming a successful scientist., The urge to know more develops the, scientific aptitude in a person. At, , a very young age, Ebright became, competitive by participating in, various county fairs. He never, , lost hope and kept on trying to do, better. In addition to curiosity and, motivation, Ebright displayed the, qualities of hard work, sincerity,, determination and patience. He also, accepted failure and success in, , the right spirit. Thus, he became a, successful scientist., , Q. 5. Richard’s mother had a great, influence on him. Discuss., , Or, , Discuss the role of Ebright’s mother, in making him a scientist., , Answer: Richard's mother played, , a huge role in making him a great
