Instructions
- Read the short biography of Leonardo da Vinci.
- Identify the four forces of flight by matching them to their descriptions.
- Follow the steps to build and test your own paper airplane designs.
- Record your flight data in the Flight Log table.
- Try the Leonardo Challenge at the end for an extra brain boost!
Leonardo: The Man Who Wanted to Fly
Over 500 years ago, a man named Leonardo da Vinci spent hours watching birds. He filled his notebooks with sketches of wings and flying machines called ornithopters. Leonardo didn't have engines or lightweight plastic, but he used his imagination and the study of nature to dream of human flight. Today, we use his ideas to build real airplanes!
Part 1: The Forces of Flight
To stay in the air, every flying object (from a bird to a paper airplane) deals with four forces. Match the force to its definition by drawing a line.
| Force | What it does |
|---|---|
| 1. Lift | The force of the air pushing the plane UP. |
| 2. Gravity | The force pulling the plane down toward the EARTH. |
| 3. Thrust | The forward PUSH you give the plane when you throw it. |
| 4. Drag | The air RESISTANCE that tries to slow the plane down. |
Part 2: The Engineering Lab
Leonardo da Vinci was an engineer. He tested his ideas many times! Now it is your turn. You will build a basic "Dart" paper airplane. Then, you will make small changes (modifications) to see how they affect the flight.
The Goal: Find out which design flies the furthest distance.
Materials Needed: Paper, paperclips, and a measuring tape or ruler.
| Design Type | Change Made | Flight Distance (cm or inches) | Observation (Did it wobble? Dive?) |
|---|---|---|---|
| Example: Basic Dart | No changes made | 120 cm | Flew straight and fast. |
| Heavy Nose | Add 2 paperclips to the front | ||
| Wide Wings | Fold wings to be wider | ||
| The Spoiler | Rip small tabs in the back | ||
| Your Invention | |||

Part 3: Thinking Like Leonardo
-
Which airplane design flew the straightest? Why do you think that happened?
-
Leonardo da Vinci studied birds to learn about flight. If you were designing a new plane today, what animal would you study for inspiration? (Example: a dragonfly, a bat, an eagle)
Part 4: The Mirror Writing Challenge
Leonardo da Vinci was famous for writing his notes in mirror script (backwards!) so others couldn't easily read them.
Challenge: Try to write your name backwards in the box below so that it looks correct when you hold it up to a mirror!

Answer Key
Part 1: Forces of Flight
- Lift: The force of the air pushing the plane UP.
- Gravity: The force pulling the plane down toward the EARTH.
- Thrust: The forward PUSH you give the plane when you throw it.
- Drag: The air RESISTANCE that tries to slow the plane down.
Part 2: Engineering Lab
- Results will vary based on student builds.
- Heavy Nose Hint: Adding weight to the nose usually makes the plane fly straighter but land sooner.
- Wide Wings Hint: Wider wings usually provide more Lift but more Drag.
Part 3: Thinking Like Leonardo
- *Open-ended answers. Encourage students to use words like "balance," "air pressure," or "weight."
- Animal inspiration ideas: Sharks (aerodynamic), Bumblebees (wing speed), Seeds (spinning flight).*
