About The Poet | Chapter 6 The Making of a Scientist

INTRODUCTION

This lesson is an account of the achievements of the great scientist Richard H Ebright when he was a growing student. He was interested in collecting butterflies, rock fossils and coins. He had a constant support, as his father died when he was in third grade, of his mother who took him on trips and bought various things for him. His interest in science began with a failure and his later understanding of how real science is all about real experiments and not a neat display. Afterwards he experimented on various things. He won various awards and was also able to discover a hormone that monarch pupa produces for its full development. This study helped him find how cells read their DNA. He had all the other qualities also. A good speaker, debater and a photographer were more stars to his personality.

Short Summary Of Chapter 6 The Making of a Scientist In English

SUMMARY

Richard has all qualities that make him a true scientist. He has curiosity and a first-rate mind. He wants to win R for the right reasons. Richard had earned the honour of publishing research work of college student. The article of Richard and his friend was published in the proceedings of the National Academy of science. He was only twenty two years old at that time. Richard grew up at reading in Pennsylvania, USA. Richard’s mother was constantly with him. She encouraged him by taking him on trips and bought him telescopes and other equipment. She found work challenge him and helped him to learn a lot. Soon he started collecting things – rocks fossils and coins. He even gazed at stars. Collecting butterflies became his hobby. He became interested in the world of science after reading a book titled The Travels of Monarch X’. The book asked the readers to study butterfly migrations. Richard came in contact with the scientist Dr. Urquhart through this book, who influenced him greatly.

Richard decided to keep butterflies at home to study their migration pattern. He started catching a female monarch and takes her eggs. He watched all the stages of development of the butterfly. Later he tagged their wings and frees them. He did this for many years and raised thousands of butterflies in the basement of his home. Richard displayed his slides of frogs at the county science fair, and realized that he needed to carry out real experiments to win an award. He took suggestions from Dr. Urquhart. As a result of his many experiments, he won many prizes at the county and international science fairs in the following years.

Ebright tried to find the cause of a viral fever in his eighth grade project that kills thousand of monarch butterflies. He thought that a beetle may carry the virus that causes viral fever, he won a prize for his project. Richard experimented on viceroy butterflies. He tried to prove that viceroys copy monarchs. Viceroys do it to protect themselves from birds as birds don’t eat monarchs. The project won the first prize in the zoology division in the county science fair.

Richard did not stop there. He continued his explorations. He was curious to know the reasons behind twelve gold spots on a monarch pupa. He and his friends built a device to prove that the spots were producing a hormone necessary for its full development. The project got him first prize in the county fair. He got third prize for zoology in the international science and engineering fair.

Richard grew cells from the wings of monarch butterfly. He further proved that cells grow into scales of wings only when they were injected with the hormone from the gold spots. He carried on his work at the Army Laboratory and laboratory of the US Department of Agriculture at Harvard He returned to the laboratory of the Department of Agriculture to identify the chemical structure of hormone and there he got the idea about cell life. He believed that his study could tell how cells read their DNA. He wrote a paper explaining theory on this with his roommate James R. Wong Richard graduated with second position in a class of 1510 students. He started experimenting to prove his new theory to prevent some types of cancer and other diseases. Richard Ebright is not only a scientist but also an all founder. He is a good debater and a public speaker. He is also a photographer and an outdoors person. His social studies teacher, Richard A. Weiherer, praises him for his will to work hard, do his best and win.

TITLE JUSTIFICATION

TITLE JUSTIFICATION

The title of the story is “The Making of a Scientist” which aptly suits it as it is a journey of a student who tries to experiment and moves on to have a discovery. A scientist is not somebody who knows science but one who is curious to experiment and discover something new. Thus it is not something one may achieve in a day but a gradual process which one sees Richard Ebright undergoing.

THEME

THEME

This lesson is the journey of a scientist whose interest and pursuing the same led him to discovery and bring some great changes in the world of science. His constant hard work could fetch him great opportunities and make him win different awards. The story tries to showcase how a failure doesn’t pull one’s motivation down rather motivates the person to move further and go into the intricacies of things by following one’s passions and interests. It also reflects how a person need not be limited to a single quality but may carry different aspects of a personality. It tries to depict how education is not a product of a beautifully wrapped mind but is a picture of a messed brain which struggles to reach goals.

MESSAGE

MESSAGE

The lesson gives the story message that hard work always pays off. If one shows dedication, preservance and determination, success can’t be left behind. Richard was an exceptional child with rare qualities of intelligent observation and keen interest in the nature of things. The traits of his successful career were nurtured and honed during his childhood itself. These qualities are definitely desirable in every child and the curiosity should never be curbed or discouraged. Providing logical answers to the of queries goes a long way to develop a scientific way of thinking and problem solving. Children learn to analyse the things and come to logical conclusions and this is indeed the correct learning procedure.

Ans. Ebright was a bright student with inclination towards research in science. He tried experiments on butterflies for a science fair. In his project, in the second year of high school, he tried to explain the

purpose of twelve tiny gold spots on a Monarch pupa. He found out that those spots produced a hormone necessary for the full development of a butterfly. He continued with his experiments even after graduation using sophisticated instruments of the university. He discovered the chemical structure of the hormone. He came across his new theory of cell life. It gave an answer to one of the questions – “How a cell can read the blue print of DNA”. His success is his continuous and sincere effort. It made a difference in his life.

 

  1. Who was Richard A. Weiherer? How did he help Richard Ebright?

Ans. Richard A. Weiherer was Ebright’s social study teacher. He had a strong influence on Ebright. He was also the adviser of two clubs – debating and Model United Nations Club. He was full of ideas and opened Ebright’s mind to new ones. A. He was pleased by Ebright for putting extra effort to prepare his debate. He said, “Here was a person who put in three or four hours at night doing debate research besides doing all his research with butterflies and other interests”. Weiherer also appreciated Ebrights’ competitive spirit. He knew the caliber and enthusiasm of Ebright to excel in whatever he does.

 

  1. How did the golden spots of Monarch butterflies lead to Ebright’s great theory?

Ans. Ebright had a sharp intellect. He had keen observation and thus won prizes in county science fair on butterflies. He tried experiments on butterflies for science fairs. In his project, in the second year of high school, he tried to explain the purpose of twelve tiny gold spots on a monarch pupa. He found out that those spots produced a hormone necessary for the full development of a butterfly. He continued with his experiments even after graduation using sophisticated instruments of the university. While looking at the X-ray photos of the chemical structure of the hormone, he came across his new theory of cell-life.

 

  1. Ebright study of monarch pupas had a far reaching impact. Elaborate.

Ans. Ebright was researching on butterflies for a long time. For a long time the scientific community had regarded the bright spots on a monarch pupa as purely ornamental. He started his experiments on the monarch pupa. He built a device with the help of another excellent students. This led to the discovery of a hormone. Richard proved that the hormone was necessary for the growth of the butterfly. This discovery got him many honours. Also it led to another important study. He began working on how cells read their DNA. DNA is the corner of heredity and is called the blueprint of life. His theory could find answer to many cancer diseases. His inquisitive and never to die faith won him stature of a scientist.

 

  1. Dr. Urquhart played a vital role in helping Ebright to become a scientist. Elaborate.

Ans. Richard was enthusiastic child who was eager to learn yet he became bored of collecting butterflies. His mother got him a book on the migration of butterflies. Richard came in contact with Dr. Urquhart through the book. Dr, Urquhart directed him to study the migration pattern of butterflies.

When he did not win any prize in the science fair in seventh grade, he again wrote to Dr. Urquhart to guide him. The scientist gave him many suggestions for new experiments. Richard performed these experiments throughout his high school and won many prizes. Motivated by Dr. Urquhart, he worked on why bright spots are found on a monarch pupa. It led to the discovery of a new hormone. The discovery of the new hormone further led to discovery of an important theory. The theory was about how cells can read their DNA. In this way, Dr. Urquhart proved to be his true mentor.
