Chapter summary
The story in steps
- Richard Ebright grows up in Pennsylvania, collects butterflies, and develops strong curiosity with his mother's steady support.
- After a contest setback, he begins serious projects and learns that real science needs questions, experiments, and careful results.
- He studies monarch butterflies and discovers that the gold spots on the pupa have an important function.
- His later research on cells and DNA brings him praise and leads to an important scientific theory.
- The writer says Ebright succeeds because of curiosity, hard work, a sharp mind, and help from his mother and teachers.

Extra questions & answers
How did Richard Ebright’s mother encourage his interest in science?
She spent time with him, took him on trips, gave him books, a microscope and other equipment, and supported his curiosity in every way.
What did Richard learn from his early science-fair experience?
He learned that simply displaying things was not real science; genuine science means asking questions and finding answers through experiments.
What was the subject of Ebright’s important research?
He studied the purpose of the gold spots on monarch pupae and how cells work, eventually proposing a new theory about how cells read their DNA.
What qualities made Richard Ebright a successful scientist?
A first-rate mind, intense curiosity, determination to win for the right reasons, and the encouragement of his mother and teachers.
How did Richard Ebright’s hobby of collecting butterflies begin?
His mother encouraged his curiosity and gave him a children’s book that drew him into collecting and studying butterflies as a boy.
What disappointment at a science fair taught Richard a key lesson?
His simple display of slides lost; he learned that real science is not just showing things but asking questions and doing genuine experiments.
What did Richard discover about the gold spots on monarch pupae?
Through careful experiments he found that the spots produced a hormone necessary for the butterfly’s full and proper development.
What important contribution did Richard make about cells?
He proposed a new theory explaining how a cell can read the blueprint of its DNA, an idea of great scientific value.
What part did his teacher Mr Weiherer play in Richard’s growth?
He challenged and guided Richard, encouraging him to think for himself, explore new ideas and look at problems in fresh ways.
What does Richard Ebright’s life teach about becoming a scientist?
That great scientists are made through curiosity, hard work, the right competitive spirit, and the steady encouragement of parents and teachers.
READ AND FIND OUT
• How did a book become a turning point in Richard Ebright’s life?
The book The Travels of Monarch X introduced Ebright to the scientific study of butterfly migration. Its invitation to tag monarch butterflies connected him with Dr Frederick A. Urquhart and changed his hobby of collecting butterflies into serious scientific work.
• How did his mother help him?
Ebright’s mother encouraged his curiosity and learning at every stage. She took him on trips, bought him scientific equipment and collecting materials, found learning activities for him, spent time working with him and contacted Dr Urquhart so that he could join the butterfly-tagging research.
READ AND FIND OUT
• What lesson does Ebright learn when he does not win anything at a science fair?
Ebright learns that a neat display is not enough for a science fair. To succeed in science, he must ask a question, form an idea and conduct a real experiment to discover something.
• What experiments and projects does he then undertake?
He first investigates whether beetles carry a viral disease that kills monarch caterpillars. Next, he tests whether birds eat monarch butterflies while studying the resemblance between monarchs and viceroys. He then investigates the purpose of the twelve gold spots on a monarch pupa and proves that they produce a hormone needed for the butterfly’s full development. Later, he grows monarch wing cells in a culture, studies the hormone’s chemical structure and develops a theory explaining how cells read the instructions in DNA.
• What are the qualities that go into the making of a scientist?
The making of a scientist requires a first-rate mind, strong curiosity, careful observation, willingness to experiment, perseverance after failure and a desire to succeed for the right reasons. Ebright also shows discipline, hard work and the habit of giving every task his best effort.
Think about it
1. How can one become a scientist, an economist, a historian... ? Does it simply involve reading many books on the subject? Does it involve observing, thinking and doing experiments?
Reading books provides essential knowledge, but it is not enough by itself. A person becomes skilled in a field by asking questions, observing closely, thinking critically, testing ideas and learning from evidence. A scientist conducts experiments, an economist studies data and human choices, and a historian examines sources and compares different accounts before reaching conclusions.
2. You must have read about cells and DNA in your science books. Discuss Richard Ebright’s work in the light of what you have studied. If you get an opportunity to work like Richard Ebright on projects and experiments, which field would you like to work on and why?
DNA, found in the nucleus of a cell, carries hereditary instructions that influence the cell’s structure and functions. Ebright’s study of the hormone produced by the gold spots on a monarch pupa showed that a chemical signal could control the division and development of wing cells. His later examination of the hormone’s structure helped him propose a theory about how cells read the instructions contained in DNA. Given such an opportunity, I would like to work in environmental biology because studying insects, plants and changing ecosystems could help protect biodiversity and solve practical environmental problems.
Talk about it
1. Children everywhere wonder about the world around them. The questions they ask are the beginning of scientific inquiry. Given below are some questions that children in India have asked Professor Yash Pal and Dr Rahul Pal as reported in their book, Discovered Questions (NCERT, 2006). (i) What is DNA fingerprinting? What are its uses? (ii) How do honeybees identify their own honeycombs? (iii) Why does rain fall in drops? Can you answer these questions? You will find Professor Yash Pal’s and Dr Rahul Pal’s answers (as given in Discovered Questions) on page 75.
(i) DNA fingerprinting is a method of identifying a person by examining distinctive patterns in the person’s DNA. It is used in criminal investigations, in establishing biological relationships and in identifying unknown bodies. (ii) Honeybees recognise their colony mainly through its particular smell. Bees belonging to the same hive share a colony odour, which guard bees use to distinguish members from outsiders. They also use visual landmarks and the Sun’s position while locating the hive. (iii) Water vapour condenses around tiny particles in clouds and forms small droplets. Surface tension pulls water into a nearly spherical shape, and droplets join together until they become heavy enough to fall as raindrops.
2. You also must have wondered about certain things around you. Share these questions with your class, and try and answer them.
Some questions I would share are: Why do leaves appear greener after rain? They look greener because rain removes dust from their surfaces, allowing them to reflect their natural colour more clearly. Why does a metal spoon feel colder than a wooden spoon in the same room? Metal carries heat away from the hand faster than wood. Why do we see lightning before hearing thunder? Light travels much faster than sound, so the flash reaches us before the sound does.
