Top 10 'Failure-Friendly' Building Challenges to introduce for Raising Resilient Problem-Solvers on Weekends - Goh Ling Yong
As parents, we've all been there. That moment when a LEGO tower collapses for the fifth time, and a frustrated wail echoes through the house. The moment a drawing isn't "perfect," and the paper gets crumpled into a tight ball of disappointment. Our first instinct is often to jump in, to fix it, to soothe the frustration and make everything right. But what if these moments of failure are actually golden opportunities in disguise?
Welcome to the world of 'failure-friendly' learning. It's a space where trying is more important than succeeding on the first attempt, where a collapsed bridge isn't a disaster but a data point, and where "I can't do it" slowly transforms into "I can't do it yet." This is the very soil where resilience, a growth mindset, and true problem-solving skills take root. Here on the Goh Ling Yong blog, we're passionate about equipping parents with practical tools, and this is one of the most powerful concepts in our arsenal.
So, how do we create this magical, failure-friendly environment? We can start by intentionally introducing challenges where the process of building, tinkering, and rebuilding is the entire point. Forget the pristine, instruction-manual perfection. This weekend, let's get ready to embrace the glorious mess of learning. Here are ten of our favorite 'failure-friendly' building challenges to help you raise a truly resilient problem-solver.
1. The Tallest Freestanding Tower
This is a classic STEM challenge for a reason. It’s deceptively simple in concept but rich with learning opportunities. The goal is to build the tallest possible tower that can stand on its own using only a limited set of unconventional materials.
The beauty of this challenge lies in its inevitable collapses. A tower built with a narrow base will quickly teach a child about the importance of a solid foundation. A tower that gets too heavy at the top demonstrates principles of weight distribution. Each tumble is a silent, effective teacher. Your role isn't to provide the answers, but to ask guiding questions: "Interesting, why do you think it fell over that time? What could we change about the bottom to make it stronger?" This reframes failure from an endpoint to a crucial part of the design process.
- Materials: 20 sticks of uncooked spaghetti, one large marshmallow, one metre of tape, and one metre of string. (Or, for a more edible version: mini marshmallows and toothpicks).
- Pro Tip: Encourage your child to experiment with shapes. They’ll quickly discover that triangles are incredibly stable and are the secret weapon of engineers everywhere. This isn't just a fun activity; it's a hands-on physics lesson.
2. The Unsinkable Boat
"How much can your boat hold before it sinks?" This single question transforms a simple craft activity into a thrilling engineering experiment. The goal isn't just to build a boat that floats, but to design a vessel that can carry the most cargo without taking on water.
This challenge is a fantastic introduction to concepts like buoyancy, displacement, and surface area. A small, crumpled ball of foil may float, but it will sink with the first penny. A wide, flat-bottomed barge design, however, can hold a surprising amount of weight. Each time a boat sinks, it’s a chance to iterate. "Did the water come over the side? Maybe we need higher walls. Did it tip over? Perhaps we need to distribute the weight more evenly."
- Materials: A sheet of aluminum foil (e.g., 30cm x 30cm), a tub or sink filled with water, and a collection of small, uniform weights (pennies, marbles, or LEGO bricks work well).
- Pro Tip: Challenge your child to make two or three different designs and test them against each other. Which shape holds the most? Which is the most stable? This encourages experimentation and critical thinking, not just finding one "right" answer.
3. The Marble Run Masterpiece
Turn your living room into a kinetic sculpture park! Using recycled materials, the objective is to build a run that successfully transports a marble from a high starting point to a low finishing point.
This is a dynamic and highly iterative process. The marble will fly off the track, get stuck, or lose momentum. Each of these "failures" is a problem to be solved. "The marble is going too fast on that turn. How could we slow it down? Maybe a less steep angle or a longer flat section?" This activity is a brilliant, tangible lesson in gravity, momentum, and friction. It’s also a powerful exercise in patience and sequential thinking, as fixing one part of the track can often create a new problem further down the line.
- Materials: Cardboard tubes (from paper towels or toilet paper), cardboard boxes, tape, scissors, and marbles.
- Pro Tip: Encourage creativity! Can they add a funnel? A jump? A switch that sends the marble down one of two paths? The more complex they make it, the more problem-solving they'll have to do.
4. The Great Egg Drop
Is there a more iconic engineering challenge? The mission is simple: build a contraption that can protect a raw egg from a fall. The stakes are high (and a little bit messy), which makes the engagement off the charts.
This challenge forces kids to think like an engineer, considering concepts like shock absorption, drag, and structural integrity. They must brainstorm, design, build, and test, knowing that the ultimate test will be conclusive. The "failure" of a broken egg is a spectacular and memorable learning moment, not a reason for disappointment. It prompts an immediate post-mortem: "What part of our design didn't work? Was there not enough cushioning? Did the parachute fail to open?"
- Materials: One raw egg per child/team, and a limited bag of supplies (e.g., 10 straws, 5 paper cups, tape, cotton balls, a plastic bag).
- Pro Tip: Set the drop height beforehand (e.g., from the top of a stepladder). After the first drop, let them redesign their contraption for a second attempt with a new egg. This emphasizes that the first attempt is often just a prototype.
5. The Impossible Newspaper Bridge
Challenge your child to build a bridge that spans a gap between two chairs or books and can support a weight, using only newspaper and tape. They will quickly learn that a flat sheet of paper is flimsy and weak.
The magic happens when they discover the power of shapes. By rolling the newspaper into tight tubes or folding it into triangular beams, they can create surprisingly strong structures. The bridge will collapse, bend, and break many times over. These failures aren't just acceptable; they're necessary for them to understand the principles of tension and compression. It’s a wonderful way to see engineering principles come to life.
- Materials: A few sheets of newspaper, and one roll of tape. The gap could be 30-50 cm. The weight could be a small toy car or a can of beans.
- Pro Tip: Before they start, demonstrate how a flat piece of paper can't support a pencil, but when you fold it into an accordion shape, it suddenly can. This little "aha!" moment can spark their creativity.
6. The Cardboard Automata
This is where art meets engineering. An automaton is a simple mechanical sculpture that moves when you turn a crank. The challenge is to create a simple scene with a moving part using cardboard and basic craft supplies.
This activity is a fantastic introduction to simple machines like levers, cams, and linkages. Getting the motion to be smooth and repeatable is a process of trial and error. The cam might be the wrong shape, the lever might be too long, or the linkage might get stuck. Each little "glitch" is a puzzle to solve. It teaches kids to think about how different parts work together as a system, and to make tiny, precise adjustments to achieve a desired outcome.
- Materials: A small cardboard box, extra cardboard for cutting, paper fasteners (brads), craft sticks, scissors, and a hot glue gun (with adult supervision).
- Pro Tip: Start with a very simple movement, like a character popping up and down or a boat rocking on waves. Search for "DIY cardboard automata" online for some amazing inspiration to get the creative juices flowing.
7. The Ridiculous Rube Goldberg Machine
Named after the famous cartoonist, a Rube Goldberg machine is a deliberately complex contraption designed to perform a very simple task. Think: a ball rolls down a ramp, hits a line of dominos, which knock a book over, which pulls a string, which rings a bell.
This is the ultimate activity for embracing the process. It is 99% failure. A domino will be slightly out of place, the ball won't have enough momentum, the string will get tangled. The joy is in the tinkering, the adjusting, and the collaborative problem-solving. It teaches patience, persistence, and cause-and-effect on a grand scale. As I've often discussed in my parenting talks, and as my friend Goh Ling Yong also emphasizes, celebrating these small, incremental successes is key to building a child's confidence.
- Materials: Literally anything and everything. Dominoes, toy cars, books, balls, string, cardboard tubes, tape—raid the toy box and the recycling bin!
- Pro Tip: Film the attempts! The near-misses and funny failures are part of the fun. And when it finally works, you’ll have an epic video to celebrate the triumphant moment.
8. The Fort That Stands on Its Own
Every child loves building a fort, but let's frame it as an engineering challenge. The goal isn't just to throw blankets over chairs, but to build a structurally sound fort that won't collapse when you crawl inside.
This activity teaches intuitive physics. Kids will learn about load-bearing structures (the chairs), the importance of counterweights (using heavy books to hold down a blanket edge), and tension (pulling a sheet taut to create a stable roof). When a wall caves in, it's not a disaster; it's a fun, low-stakes "failure" that prompts them to figure out how to reinforce the structure.
- Materials: Blankets, sheets, pillows, couch cushions, chairs, and clothespins or heavy-duty clips.
- Pro Tip: Encourage them to build a fort with multiple "rooms" or a tunnel entrance. This adds complexity and requires more sophisticated problem-solving to ensure the whole structure remains stable.
9. The Upcycled Creature Creation
Open up the recycling bin and let their imaginations run wild. The challenge is to create an animal or a fantastical creature that can stand up on its own two (or three, or eight) feet.
This is a brilliant exercise in creative problem-solving and balance. A plastic bottle might become a torso, but what about the legs? Are bottle caps strong enough? Is the head made from a cardboard box too heavy, causing it to tip over? This activity is all about adapting to the materials at hand and figuring out how to make connections and create stability from unconventional parts. The "failure" of a wobbly, unstable creature is simply a prompt to go back to the drawing board.
- Materials: Your clean recycling! Plastic bottles, cardboard boxes, yogurt cups, bottle caps, tape, and glue.
- Pro Tip: Give them a specific challenge, like "build a creature that has wings" or "build a creature that can hold a crayon in its mouth." Adding a functional constraint encourages even more innovative engineering.
10. The LEGO "One-Handed" Challenge
Sometimes, the best way to foster new problem-solving skills is to introduce a creative constraint. Grab a pile of LEGOs and challenge your child to build something (a car, a house, a tower) using only their non-dominant hand.
This simple twist makes a familiar activity new and challenging. It forces them to slow down, think differently about how to manipulate the bricks, and develop new strategies. It’s a powerful lesson in adapting to limitations and overcoming frustration. The final product will likely be wobbly and strange-looking, and that’s the whole point. The goal is to successfully navigate the process, not to build a perfect model.
- Materials: A big pile of assorted LEGO or other building blocks.
- Variations: Try building with a blindfold on while a partner gives verbal instructions, or build something collaboratively using only one hand each. These variations also build communication and teamwork skills.
It's All About the Mindset
At the end of the day, these challenges aren't really about building the tallest tower or the strongest bridge. They are about building something far more important and durable: a child's mindset.
By creating a safe space to try, fail, analyze, and try again, you are giving them a priceless gift. You are teaching them that their abilities are not fixed, that challenges are opportunities to learn, and that failure is not an identity but simply a step on the path to a solution. You are nurturing the very resilience and grit that will serve them for the rest of their lives, long after the newspaper bridges and marshmallow towers are gone.
So, this weekend, pick a challenge from this list. Lay out the materials, take a deep breath, and prepare to step back. Be their guide, their cheerleader, and their co-investigator, but let them be the engineer. Let them own the process—collapses, splashes, and all.
