Ebright's Experiments and Discoveries: The Making of a Scientist

Updated 17 October 2026 · Draft, not yet fact-checked

Richard Ebright moved from collecting butterflies to tagging monarchs, then to real experiments: a viral disease in beetles, viceroys copying monarchs, the gold spots on a monarch pupa, and finally a theory on how a cell reads its DNA blueprint. Each step added the skills of curiosity, effort and honest ambition that the chapter says make a scientist.

Notice how each step moves from simply collecting things to doing real experiments, building curiosity, effort and ambition along the way.

Understand Richard Ebright's Experiments and Discoveries, Step by Step

Starting with collections. Richard Ebright was an only child who grew up north of Reading, Pennsylvania. With no team to play with, he collected things: butterflies from kindergarten, and also rocks, fossils and coins. By the second grade he had collected all twenty-five species of butterflies around his hometown.

The tagging project. His mother gave him The Travels of Monarch X, a book about monarchs migrating to Central America. It invited readers to tag butterflies for Dr Frederick A. Urquhart of the University of Toronto. His mother wrote to Dr Urquhart, and Richie began tagging monarchs. The local season lasted only six weeks, so he raised thousands of monarchs in his basement. Later, he lost interest because tagging was tedious and gave little feedback; only two of his tagged butterflies were ever recaptured.

The lesson from a lost science fair. In the seventh grade he lost with neat slides of frog tissues, and realised the winners had tried to do real experiments, not simply make a neat display. He wrote to Dr Urquhart, who sent ideas for experiments.

Real experiments. In the eighth grade he tested whether a beetle carried a viral disease that killed monarch caterpillars; he got no real results but won for his effort. The next year, he tested the theory that viceroys copy monarchs because monarchs taste bad to birds. A starling refused ordinary bird food but ate all the monarchs it could get; he later noted that research by others showed viceroys probably do copy the monarch. This project came first in zoology and third overall.

The gold spots. In his second year of high school, he studied the twelve tiny gold spots on a monarch pupa, which everyone assumed to be ornamental. With another student he built a device showing that the spots produced a hormone necessary for full development. As a senior he showed that wing cells grown in a culture developed into normal scales only when given the hormone. After his first year at Harvard, he identified the hormone's chemical structure.

The theory. In his junior year at Harvard, X-ray photos of a hormone gave him an idea about how a cell reads its DNA blueprint. He and his room-mate James R. Wong worked all night and wrote the paper, which was published when he was twenty-two.

The pattern. Collect, then tag, then experiment, then explain. The chapter's recipe: a first-rate mind, curiosity and the will to win for the right reasons.

Why did Richie lose interest in tagging butterflies? Answer in 30-40 words.

Try it first, then show the solutionSolution

Tagging was tedious (1).
He received little feedback; only two tagged butterflies were recaptured (1).

Answer: Richie lost interest in tagging because it was tedious and gave very little feedback. Although he raised thousands of monarchs and tagged them, only two of his tagged butterflies were ever recaptured, so it seemed pointless.

Example 3: The lost science fair · 3 marks · Short answerHarder board level

What did Richie learn from losing in the seventh-grade science fair? Answer in 40-50 words.

Try it first, then show the solutionSolution

He had made a neat display of frog tissue slides (1).
The winners did real experiments (1).
He asked Dr Urquhart for ideas (1).

Answer: Richie lost with neat slides of frog tissues and realised that the winners had tried to do real experiments, not just make a neat display. He wrote to Dr Urquhart, who sent a stack of ideas, and from then on he chose projects that tested a question.

Example 4: The gold spots · 3 marks · Short answerHarder board level

What did Ebright discover about the gold spots on the monarch pupa? Answer in 40-50 words.

Try it first, then show the solutionSolution

Everyone thought they were ornamental (1).
He and another student built a device (1).
The spots produced a hormone needed for development (1).

Answer: Everyone assumed the twelve tiny gold spots on a monarch pupa were just ornamental. Ebright and another student built a device and showed that the spots produced a hormone necessary for the butterfly's full development. This won him prizes and showed his habit of questioning accepted ideas.

Example 5: What makes a scientist · 6 marks · Long answerHOTS / competency

Using Ebright's example, discuss the qualities that make a scientist, with reference to his projects, in 100-120 words.

Try it first, then show the solutionSolution

Curiosity and effort (2).
Learning from failure (2).
Support and the right reasons (1).
Expression (1).

Answer: Ebright's story shows that a scientist needs curiosity, effort and the will to win for the right reasons. He collected butterflies out of curiosity and tagged monarchs for months. When he lost at a science fair, he learnt that real experiments count more than displays, and changed his approach. He questioned what everyone assumed, as with the gold spots, and put in extra effort throughout. His mother's support and Dr Urquhart's guidance also helped. The chapter's recipe of a first-rate mind, curiosity and the will to win sums this up. His example shows that scientists are made through steady effort and honest ambition.

What did Ebright's starling experiment test, and what did it find? Answer in 40-50 words.
Hint
Testing a theory about copying.
Answer
The theory said viceroys copy monarchs because monarchs taste bad to birds. Ebright tested whether birds would eat monarchs: a starling refused ordinary bird food but ate all the monarchs it could get. It was a real experiment and won first place in zoology.
Q4 · 3 marks · Short answerHarder board level
What does the writer mean by saying that he wants to win for the right reasons? Answer in 40-50 words.
Hint
Love of the subject, not prizes alone.
Answer
The writer means that Ebright wants to be the best, but his motive is his interest in discovering something, not prizes or praise alone. His teacher Mr Weiherer says he always gives extra effort. Winning for the right reasons means working honestly and for the subject itself.
Q5 · 6 marks · Long answerHOTS / competency
A friend says that scientists are born with talent and that effort matters little. Reply using Ebright's story in 100-120 words.
Hint
Talent with effort and support.
Answer
I disagree with my friend. Ebright had a sharp mind, but the chapter shows that his success came from effort, curiosity and support. He collected and raised thousands of monarchs, wrote letters to experts and spent evenings learning with his mother. When he lost at the science fair, he did not give up; he learnt that experiments matter and began again. He built devices, repeated tests and worked all night to write his paper at Harvard. The closing recipe of a first-rate mind, curiosity and the will to win shows that talent is only the start. Without hard work, it would not have produced discoveries.
