As you read, pay attention to Thomas Edison’s lines. What do they tell you about his attitude toward succeeding?  

Prologue

N1: In the 1870s, inventor Thomas Edison built a laboratory in Menlo Park, New Jersey.

N2: Edison believed that to invent something, all you needed was a good imagination and a pile of junk.

N3: He hired a team of mechanics, mathematicians, and engineers to help him.

N1: Edison and his men worked on many different ideas. But he became focused on solving one big problem.

N2: Back then, people lit their homes with candles or with lamps that burned oil or gas.

N3: The flames were dangerous. They caused fires and created harmful fumes and black soot.

N1: Edison wanted to find a new and safer way to light up the world.

N2: And he wouldn’t give up until he found it.

Thomas Edison: Nothing is impossible. We just don’t know how to do it yet.

The Wizard
People from around the world flocked to Edison’s lab for a glimpse of his inventions. He became known as “The Wizard of Menlo Park.”

Scene 1

N3: Twelve-year-old Alfred is picking through the trash heap outside Edison’s laboratory.

N1: A man comes out a side door. His hair is uncombed, and he wears a rumpled blue suit.

Edison: Hey there, boy. What have you got?

N2: Alfred slowly opens his hands.

Alfred (shyly): Um, copper wire and glass tubing.

Edison: What do you plan to do with this treasure?

Alfred: I’m going to experiment. I hope to be an inventor like Mr. Edison someday.

Edison: Today may be your lucky day. Come with me.

N3: Edison takes Alfred into the lab.

N1: Machines whir. The smell of burning metal fills the air. Men huddle around worktables heaped with parts and tools.

N2: Edison leads Alfred to a table covered with threads.

Edison: We are working on an incandescent lamp. Do you know what that is?

Alfred: It’s light that glows instead of flickers?

Edison: That’s right. We put a long, thin strand of some material into this glass bulb. That strand is called a filament. It heats and glows when electricity runs through it.

N3: Alfred watches a large, bearded man delicately pluck a fiber from a coconut shell.

Charles Batchelor: Problem is, we can’t find a filament that burns long enough. We’ve tried plants, paper, all kinds of metals. Now we’re trying this coconut fiber.

Edison: When you have exhausted all possibilities, remember this: You haven’t. Right, Batch?

Batch: Right, Boss.

N1: Alfred’s eyes go wide.

Alfred: You . . . you’re the boss?

N2: Edison winks at Alfred and tips an imaginary hat.

Edison: Mr. Edison, at your service.

Scene 2

N3: Alfred starts helping Edison in his lab. He brings supplies, carries water, and runs errands.

N1: One day, Alfred is tidying the worktables when J.P. Morgan, one of Edison’s investors, arrives waving a newspaper.

J.P. Morgan: Have you seen this headline? “Is Edison a Fake?” See that? A fake!

Edison: Nice to see you too, J.P.

Morgan: You said you were close to making incandescent light. You claimed gaslight would soon be a thing of the past. That was a year ago!

Edison: Electric light has turned out to be more complicated than I thought.

Morgan: Other scientists have already made working lamps.

Edison: True, but they don’t burn for more than a few minutes.

Morgan: If you don’t solve this soon, you’ll get no more money from me. Seems like you and your team just keep failing.

Edison: We have not failed. We have successfully found thousands of ways that won’t work. Don’t you see? Every failure is a step forward.

Morgan: Every failure is a failure.

N2: Morgan storms off.

Dangerous Light
Before the use of electric light, fires involving candles and gas lamps were common.

Scene 3

N3: At Alfred’s home, Mama is teaching Lillie to make dinner. A large bandage is wrapped around Mama’s right arm.

Mama: Now we’re going to chop those potatoes in half and drop them into the boiling water.

Lillie: Here Mama, let me do it. The doctor said you need to rest your arm to help the burns heal.

Mama (shaking her head): Your clumsy mama . . . I still don’t know how I managed to knock over that lamp last week. We’re lucky the whole house didn’t burn down.

N1: Papa comes in with an empty milk jug.

Papa: Where’s your brother, Lillie?

Lillie: In the barn.

N2: Papa goes outside just as flames dart from the barn. He grabs a bucket of water and rushes in.

N3: Alfred is swatting at a growing fire. Papa tosses the water on it.

Papa: What on Earth is going on in here?

Alfred (quietly): I was burning pieces of fishing line, and the hay caught fire.

Papa: What’s all this about?

Alfred: Papa, I met Mr. Edison. He’s making an electric lamp, and I’m going to help!

Papa: You will do no such thing. You’ve been neglecting your chores, Alfred, and I have had it with you.

Alfred: But Papa, I have to! Mama could have died in that fire. I saw it, Papa. The way the flames raced up her sleeve . . . It never would have happened if we had electric lights instead of oil.

Papa (softening): It was a terrible accident, son. But judging from this fire you started, electric lights will be just as dangerous.

Alfred: They will be so much safer. No open flames, no dripping oil or leaking gas. Please believe me, Papa. Mr. Edison is going to change the world!

Papa: You will stop these experiments. That is my final word.


Scene 4

 Gas streetlamps had to be lit by hand each evening by people called lamplighters.

N1: In the following months, Edison and his men continue their search for the perfect filament.

N2: Edison often works late into the night, forgetting even to eat.

N3: Finally, in late October 1879, Edison and Batch make a breakthrough.

Batch: I baked these cotton threads in the oven until they charred, just like you asked.

Edison: Excellent. We’ll use them as filaments in the lamps we’re testing tonight.

Batch: OK. We’ve also got filaments made of horsehair, paper dipped with tar, fishing line, and red cedar wood.

N1: Edison and Batch watch the lamps all night.

Edison: Lamp Number 2 has gone out. It’s 11 p.m.

N2: Batch writes down the time in his notebook.

N3: One by one, the other lamps flicker out or grow dim.

N1: Except for the one with cotton thread.

Batch: This one is still going strong.

Edison: Let’s turn up the power.

N2: The lamp glows for another hour before the glass overheats and cracks.

Edison: That’s 13-and-a-half hours.

Batch: The longest ever!

Edison: If we can make a lamp that lasts 13 hours, we can make one that lasts 100 hours.

Scene 5

N3: Two months later, Alfred comes to Edison’s lab.

Edison: Ah, my young scientist friend! Where have you been?

Alfred: My papa told me I’m not supposed to come here anymore. I almost burned down our barn.

Edison (chuckling): What were you doing?

Alfred: Burning stuff, trying to find a filament for you.

N1: Batch walks over, carrying a newspaper.

Batch: Why, hello there, Alfred. Boss, I thought you might want to see this headline.

Edison (reading): “Edison’s Light: The Great Inventor’s Triumph in Electric Illumination.” That’s more like it.

Alfred: I wish my father understood how life-changing this is.

Edison: We’ve got a little something to show the world on New Year’s Eve. Why don’t you bring your family?

How Does a Light Bulb Work?

  1. Electricity travels into the light bulb through the base.
  2. The electricity causes a long strand of material, or filament, to heat up and
    glow.
  3. The glass bulb keeps air out. Without it, the filament would catch on fire.

Scene 6

N2: On the night of December 31, as Alfred and his family are finishing dinner, Alfred clears his throat nervously.

Alfred: There’s something amazing I want to show you all. Will you come for a walk with me?

Papa: Alfred, it’s freezing outside. And you kids have to help your mother with the washing-up. Nobody’s going anywhere.

Alfred: Please, Papa. Trust me. You need to see this.

Lillie (excitedly): What is it?

Alfred: It’s a surprise.

Mama: Alfred, you didn’t even look this excited on Christmas morning!

N3: Alfred, Lillie, and Mama all turn to Papa hopefully.

Alfred (to Papa): I promise you won’t be sorry.

Papa (sighing deeply): Well, all right. But make it quick, before we all catch cold.

N1: Alfred leads his family outside and up the hill to Edison’s lab. Rows of soft, glowing lamps on tall poles illuminate the street.

Lillie: What are those?

Alfred: Electric lights. Aren’t they beautiful?

N2: Mama walks toward the lights in awe.

Mama: I’ve never seen anything like it.

N3: Papa whistles softly and shakes his head.

Papa: I have to say, they are something.

N1: Edison comes to the door to greet them. Warm, lovely light spills out of the lab.

Edison: Welcome, welcome. You must be Alfred’s family.

Papa: Sir, I’m absolutely amazed by these lamps. They don’t flicker or sputter or hiss.

Alfred: I told you, Papa. Edison is a true genius.

Edison: Genius, my young friend, is 1 percent inspiration and 99 percent perspiration.

Papa: Well, your hard work has paid off.

N2: Alfred leads his family to a table where Batch is turning a lamp on and off.

Alfred: See, these wires are attached to that U-shaped filament. When the electricity flows through, the filament gets really hot and starts to glow.

Mama: And that’s what makes the light?

Alfred: Yes, Mama. It can stay lit for more than 100 hours. And it’s so much cleaner and safer than oil or gas.   

Edison (to Mama and Papa): Your son has impressed me. I’d like to make him an official part of my team.

N3: Mama puts her arm around Alfred’s shoulders. Alfred is beaming.

Papa (with pride): Son, I can see you have a bright future.

Edison: We will find out what the world needs, then try hard to invent it. Right, Alfred?

Alfred: Right, Boss.

The play includes words related to lighting, such as filament, incandescent, and illumination.

Knowledge Demands 

Some familiarity with Thomas Edison will aid comprehension but is not required.

Step-by-Step Lesson Plan

1. Preparing to Read

Preview Text Features and Vocabulary (20 minutes, activity sheet online)

  • As a class, look at page 22. Ask: Who is the play about? Based on what you see in the picture or what you already know about Thomas Edison, what is he famous for? Discuss: How might light have “changed the world,” as the subtitle says?
  • Give students a few moments to look at the other text features in the play. Then read the Up Close box on page 23 to the class. Share with students that a number of Edison’s lines are adapted from his actual quotes.
  • Introduce the highlighted words with our vocabulary slideshow or vocabulary activity. Highlighted words: soot, incandescent, filament, investors, neglecting, illumination, official

2. Reading the Play

Read and Unpack the Text (45 minutes, activity sheet online)

  • Assign parts and read the play aloud as a class. After reading, discuss the close-reading and critical-thinking questions.

Close-Reading Questions (20 minutes, activity sheet online)

  • Based on the Prologue, what main problem will Thomas Edison face in the play? Why does he want to solve it? (problem and solution) Edison wants to find a new, safer way to light people’s homes and other places, because the candles and lamps in use at the time cause fires and create dirty, smelly fumes.
  • In Scene 1, Edison and his team are searching for the best filament for a light bulb. Based on this scene and the diagram on page 26, why is the filament important? (key detail, text features) The filament inside a light bulb is what glows and creates light when it is heated up with electricity. The men need to find one that will burn for a long time.
  • In Scene 2, how do J.P. Morgan’s ideas about invention differ from those of Edison? (compare and contrast) J.P. Morgan believes that inventing is successful only when it works. He measures success by the time or number of tries it takes to invent something (and probably also by the money he has to spend versus money earned). Edison sees invention as a process that requires failing and trying again for as long as it takes to succeed.
  • Based on Scene 3, why does Alfred want to help invent electric light? How does this connect to what you read in the Prologue? (character’s motivation) Alfred’s mother was badly burned in a fire started by an oil lamp. Alfred wants to help create electric light so his family will no longer be at risk of such terrible accidents. The Prologue also explains that flames from gas or oil lamps caused dangerous fires.
  • Reread Edison’s last line in Scene 4. What does it tell you about him? (character) The line tells you that Edison has confidence that his team can achieve anything if they just keep trying. Also, he doesn’t want to settle for something that is just OK; he wants to keep working to make it the best.
  • How does Papa change in Scene 6? (character) Before Scene 6, Papa is opposed to Alfred’s working with Edison and thinks electric lights will be just as dangerous as oil or gas ones. At the beginning of the scene, he resists going outside to see what Alfred wants to show the family. But once Papa sees the magnificent electric lights leading to Edison’s lab, he changes his mind and realizes the importance of the invention. He allows Alfred to continue working for Edison.

Critical-Thinking Question (activity sheet online)

  • This play is a work of historical fiction. That means it includes real people, settings, and events in a fictional story. Why do you think the author wanted to tell the true story of Edison and his invention of the lightbulb through the fictional story of Alfred? (genre) The author probably wanted to make Edison’s story relatable by including a character who is young like the readers. Sometimes reading about historical figures in a story can make them seem more alive and understandable than reading about them in a history text. (You might hold a discussion with students about which genre they prefer!)
  • Choose one of Edison’s lines from the play. Explain it in your own words and what big idea it expresses from the play. (theme) Answers will vary. Students might choose the lines “When you have exhausted all possibilities, remember this: You haven’t,” or “Genius is 1 percent inspiration and 99 percent perspiration.”

3. Skill Building

Featured Skill: Theme

  • As a class, read the writing prompt on page 27. Have a quick brainstorm about which ideas from the play students might include in their letters. Then distribute the theme activity and have students complete it in small groups.
