Instructions
Welcome, Chief Engineer! Today, you are going to step back in time to learn about Henry Ford and his game-changing invention: The Assembly Line. Follow these steps to complete your factory training:
- Read the short story about Henry Ford below.
- Solve the "Assembly Line Quick Check" questions.
- Complete the hands-on "Drawing Assembly Line" activity with a partner or family member.
- Fill out the Assembly Line tracker table.
- Answer the "Big Thinker" challenge question at the end!
The Story of Henry Ford and the Model T
Imagine a world with no traffic jams, no highways, and no gas stations. In the early 1900s, most people still traveled by horse and buggy! Cars existed, but they were built one by one. It took a very long time to make just one car, and they were so expensive that only super-rich people could buy them.
Henry Ford wanted to change that. He wanted to make a car that normal families could afford. This car was called the Model T (nicknamed the "Tin Lizzie").
To make it cheap, he had to make it fast. Instead of having one person build an entire car from scratch, Ford created the Assembly Line.
Here is how it worked:
- The car frame moved down a conveyor belt.
- Workers stood in one spot.
- As the car passed them, each worker added just one part over and over again.
- One person put on the left wheel, the next person tightened the bolts, and the next added the steering wheel!
This simple idea changed the world. Before the assembly line, it took 12 hours to build one Model T. After the assembly line was invented, it took only 93 minutes!
Activity 1: Assembly Line Quick Check
Draw a line to match the word on the left to its correct meaning on the right!
- Model T A. A moving track that carries parts past workers.
- Assembly Line B. The affordable car invented by Henry Ford.
- Conveyor Belt C. A system where each worker does one job to build something fast.
Activity 2: Hands-On Challenge - The Drawing Factory!
Now, you are going to run your own assembly line factory. Your goal is to manufacture (draw) 4 identical Speedy Race Cars as fast as possible!
The Setup: Find a partner (a friend, classmate, or parent). You are now Worker A and Worker B.
- Worker A's Job: Draw the wheels and the main body of the car.
- Worker B's Job: Draw the spoiler (the wing on the back), the driver's window, and color it in!
The Process:
- Worker A starts drawing on a blank sheet of paper.
- As soon as Worker A finishes their parts, they "slide" the paper to Worker B.
- Worker B finishes the drawing while Worker A starts the next car on a new piece of paper!
Use the table below to plan and track your assembly line steps.
| Step Number | Task / Part to Add | Who Does It? | Time Taken (Estimate) |
|---|---|---|---|
| Example: Step 1 | Draw 2 round wheels and car body | Worker A | 15 seconds |
| Step 2 | |||
| Step 3 | |||
| Step 4 | |||
| Step 5 | |||
Note: Leave plenty of room in the blank cells to write your jobs and times!
Activity 3: Big Thinker Questions
-
How did it feel to do the same drawing job over and over again? Did you get faster at it as you practiced?
-
The Challenge Question: Henry Ford famously said his customers could have the Model T in "any color they want, as long as it is black." Why do you think he only wanted to paint the cars black? (Hint: Think about how fast paint dries!)
Answer Key
Activity 1: Assembly Line Quick Check
- Model T -> B. The affordable car invented by Henry Ford.
- Assembly Line -> C. A system where each worker does one job to build something fast.
- Conveyor Belt -> A. A moving track that carries parts past workers.
Activity 2: Hands-On Challenge Table
Student responses will vary depending on how they split up tasks, but a correct chart should look similar to this structure:
- Step 2: Draw the back spoiler / Worker B / 10 seconds
- Step 3: Draw the driver's window / Worker B / 5 seconds
- Step 4: Color the car red / Worker B / 20 seconds
- Step 5: Quality Check / Worker A & B / 5 seconds
Activity 3: Big Thinker Questions
- Accept all reasonable student reflections. Example: "It felt a bit boring at first, but I got much faster because I didn't have to switch pencils!"
- Correct Answer: Black paint dried the fastest of all the colors in the early 1900s. Using only black paint meant the cars didn't have to sit around waiting to dry, which kept the assembly line moving fast!
