Leonardo’s Laboratory

Everything you need to know before you begin.

Overview

Leonardo’s Laboratory

Leonardo da Vinci (1452-1519) was one of history’s great observers.  Leonardo looked at the world with endless curiosity.  He studied plants, animals, rivers, clouds, machines, and the human body in great detail.  Wherever he looked, he saw questions waiting to be answered.  Few things fascinated Leonardo more than flight, and he long pondered the question: Could people learn to fly?

In this unit, students join Leonardo on an Italian hillside as he studies the birds soaring overhead.  Together they will watch wings in motion, examine the shapes of feathers, and investigate the patterns hidden within flight.  Like Leonardo, students will discover that nature often provides the clues needed to solve difficult problems. 

As the unit progresses, students move from observation to invention.  They will design and test paper airplanes, compare different wing designs, experiment with rocket-powered flight, and explore how parachutes can slow a falling object.  Throughout the unit, they will follow the same process Leonardo used in his notebooks: observing carefully, asking questions, developing ideas, and testing those ideas through experimentation.

By the end of the unit, students will have explored many of the forces and design challenges involved in flight. More importantly, they will experience the habit of mind that made Leonardo extraordinary.  He believed that careful observation was the beginning of discovery, and that every question was an opportunity to investigate.  This unit invites students to step into that same spirit of curiosity as they explore one of humanity’s greatest dreams: leaving the ground and taking to the sky.

Schedule

There are four lessons in this unit.  Lessons can usually be completed in 90 minutes, depending on how much time you spend testing, redesigning, and extending the projects.

Lesson 1 – Flying with Leonardo

Lesson 2 – Ornithopters and Paper Airplanes

Lesson 3 – Rockets

Lesson 4 – Parachutes

Materials Needed

This curriculum works best with The Laboratory: Apprentice Journal (available on Amazon here).  Each lesson includes instructions to record observations and test results in that journal. 

All lessons involve projects.  Most materials needed for these projects are common household items.  The following are less common items you will need.

    • Binoculars (optional but helpful)
    • Smartphone or camera capable of slow-motion video
    • Timer or stopwatch (a smartphone is fine)
    • Duct tape
    • String
    • Balloons
    • Drinking straws
    • Plastic water bottle
    • Vinegar
    • Baking soda
    • Paper towels
    • Measuring tape
    • One or more eggs (or water balloons as substitutes)

The Lessons

1. Flying with Leonardo

Students meet Leonardo on a hillside and join him as he watches birds in flight.  With Leonardo, students make careful observations of birds in motion, recording their observations about wing shapes, flight patterns, and movement.  Through direct observation and video analysis, students begin to recognize that different birds are designed for different types of flight.  They will compare their observations with sketches from Leonardo’s notebooks and discover how careful observation can lead to new questions and new ideas.

2. Ornithopters and Paper Airplanes

After years of observing birds, Leonardo filled notebooks with ideas for flying machines.  In this lesson, students explore some of those designs and investigate one of the central challenges of flight: wing design.  Students build and compare multiple paper airplane designs, measuring their flight distance, hang time, and flight stability and comparing the planes’ performances.  Through repeated testing and redesign, students experience the engineering process and discover how changes in design affect performance.

3. Rockets

Leonardo recognized that wings alone are not enough.  A flying machine also needs a way to move forward through the air.  This lesson introduces students to the concept of thrust through some rocket-inspired challenges.  Students will build and test balloon-powered rockets and chemical-reaction rockets, observing how escaping gases create forward motion.  The lesson encourages students to think creatively, test multiple solutions, and evaluate which designs provide the greatest launching power.

4. Parachutes

The final lesson explores another challenge faced by anyone attempting flight: coming back down safely.  Students examine one of Leonardo’s parachute designs and consider how a simple fabric canopy can dramatically slow a falling object.  Students then take on an engineering challenge of their own by designing and building parachutes capable of safely delivering an egg dropped from a significant height.  After testing their designs, they will analyze what worked, what failed, and how improvements might be made.  The lesson concludes by connecting Leonardo’s ideas to later advances in aviation and highlights how centuries of experimentation eventually led to successful human flight.
