The Paper Bridge Challenge 🌉

Goal: Design and build the strongest paper bridge you can using limited materials. This explores basic engineering principles.

Your Challenge: Can you build a bridge out of paper and tape that can hold the most weight?

Materials:

  • Sheets of standard paper (e.g., 20-30 sheets per group)
  • Roll of tape (e.g., masking tape or clear tape)
  • Two supports (e.g., stacks of books, table edges) set a specific distance apart (e.g., 20 cm or 8 inches)
  • Objects to use as weights (e.g., pennies, washers, small books, phone)
  • A ruler

Let’s Get Building!

  1. Brainstorm & Design (5-10 min):
    • How can you make paper stronger? Think about folding, rolling, or creating shapes.
    • Sketch a few ideas for your bridge design. Consider how real bridges are built. What shapes do you see? (Triangles are super strong!)
  2. Construct (15-20 min):
    • Use only the paper and tape provided to build your bridge.
    • Your bridge must span the gap between your two supports.
  3. Test & Improve (10-15 min):
    • Carefully place your bridge across the gap.
    • Slowly add weight to the center of your bridge, one item at a time.
    • Record how much weight your bridge holds before it collapses or bends significantly.
    • What part failed? Why? How can you make it stronger? Try a new design or modify your existing one!

Think About It:

  • What design features made some bridges stronger than others?
  • How did different folding techniques affect the strength?
  • Connections: Civil engineers design bridges, roads, and buildings. They use principles of physics and material science. University paths could include Civil Engineering, Mechanical Engineering, or Materials Science.

Paper Airplane Flight School ✈️

Goal: Explore the principles of flight and aerodynamics by designing and testing paper airplanes.

Your Challenge: Design a paper airplane that can fly the farthest distance.

Materials:

  • Various types of paper (e.g., copy paper, construction paper, cardstock – optional, but good for experimentation)
  • Tape (optional, for securing folds or adding small weights like paperclips)
  • Measuring tape
  • An open area for test flights (hallway, outdoor space)

Let’s Take Flight!

  1. Design & Fold (10-15 min):
    • Start with a basic paper airplane design, or look up some different folding techniques.
    • Think about what makes an airplane fly:
      • Lift: How do the wings create upward force?
      • Drag: How does air resistance slow it down?
      • Weight: How does the plane’s weight affect its flight?
      • Thrust: How will you launch it for best results?
  2. Test Flights & Modifications (15-20 min):
    • Find a starting line. Throw your airplane and measure the distance it travels.
    • Observe its flight: Does it fly straight? Does it nosedive or stall?
    • Make small changes to your design:
      • Adjust the wing flaps (elevators and ailerons).
      • Change the nose weight (e.g., add a paperclip or fold it differently).
      • Try different throwing styles.
    • Test it again after each modification. Keep track of what works best!
  3. Distance Competition (5-10 min):
    • Everyone gets a few official throws with their best design.
    • Measure the distance for each throw.
    • Whose plane flew the farthest?

Think About It:

  • What design features helped planes fly farther or straighter?
  • How did changing the wing shape or adding weight affect the flight?
  • Connections: Aerospace engineers design airplanes, spacecraft, and missiles. They study aerodynamics, propulsion, and materials. University paths could include Aerospace Engineering, Mechanical Engineering, or Physics.

Have fun exploring and discovering!

🍝 The Marshmallow Tower Challenge

🎯 Build the tallest freestanding structure—with a marshmallow on top!


🧠 What Is This Challenge All About?

You and your team will have 18 minutes to build the tallest freestanding structure possible using spaghetti, tape, and string…
But here’s the twist: The marshmallow must go on top—and stay there! 🏗️


🧰 What You Get (per team):

  • 20 sticks of uncooked spaghetti 🍝

  • 1 yard of masking tape 🎗️

  • 1 yard of string 🧵

  • 1 standard marshmallow 🍡

  • 1 pair of scissors ✂️ (optional)

That’s it. Use your materials wisely!


🔧 The Rules:

  1. You have 18 minutes to build. ⏱️

  2. Your structure must be freestanding (no leaning on walls, books, or people). 🏛️

  3. The entire marshmallow must sit on top—don’t squish it!

  4. You can break or cut the spaghetti, tape, or string any way you like.

  5. At the buzzer, the tallest structure that can stand on its own wins! 🏆


💡 Tips Before You Build:

  • Test your ideas early! Don’t wait until the last second to add the marshmallow.

  • Think about triangles and strong bases for support.

  • Communicate with your team—divide roles and sketch a quick plan.

  • Keep it simple. Fancy isn’t always stable! 😉


🧠 Challenge Time: Ready, Set… GO!


 

🗣️ Debrief & Reflect:

  • What was your strategy?

  • What worked—and what didn’t?

  • How did your team communicate under pressure?

  • What would you change if you had 5 more minutes?


🚀 What You’re Practicing:

  • Design thinking & prototyping

  • Creativity under constraints

  • Teamwork & communication

  • STEM problem-solving in real time
