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!
- 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!)
- 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.
- 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!
- 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?
- 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!
- 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:
-
You have 18 minutes to build. ⏱️
-
Your structure must be freestanding (no leaning on walls, books, or people). 🏛️
-
The entire marshmallow must sit on top—don’t squish it!
-
You can break or cut the spaghetti, tape, or string any way you like.
-
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
