STEAM Event Summary
During the 200-minute STEAM programme, 3rd graders will develop creativity, problem solving, critical thinking, resilience, valuing people, curiosity, a sense of wonder and openness through 7 phases of building spaghetti and marshmallow pyramids. The activity develops these skills while students create models of pyramids and identify points, lines and angles. Teams practice problem solving, as well as evaluating others’ ideas and being open to them by designing stable structures within strict quantitative constraints to avoid wasting resources. Through two tests of construction (prototyping, evaluation and improvement), learners strengthen their resilience and flexibility by adjusting their designs in case of structures faltering or breaking. The project concludes with a reflection where students compare their results and use geometric vocabulary to explain their team’s success.
SPIRIT Skill Focus
- Problem-solving
- Critical thinking
- Flexibility
- Resilience
Complementary/Secondary SPIRIT Skill(s)
- Valuing people and nature (resource stewardship: limited materials, reuse, waste minimization)
Basic Information Sheet
Age group Student number Duration Number of stages Subjects connection and relevance 3rd grade (core activity; extensions for Grades 4–5 in “Difficulty level tailoring notes”) Whole class
(max ~30 students)180–200 minutes (plus optional extension time) 7 stages Mathematics – Geometry (3D shapes + Euclid-style vocabulary: point/line/parallel/angle) The Spaghetti Marshmallow activity is designed to get learners working together to build and test their designs with an emphasis on radical collaboration and bias to action. This STEAM exercise is a great way to push students to build, test, and iterate. This activity also encourages critical thinking by asking students to synthesize what they learned quickly to create new designs. Students must also demonstrate resilience in the face of challenges or frustrations.
National curriculum Link and Objectives
- Recognize and use geometry vocabulary: point, line/straight line, parallel lines, angle
- Identify and compare solids: triangular pyramid, square pyramid, rectangular pyramid
- Understand that pyramids are named by their base shape
- Apply spatial reasoning and geometric language while building a 3D model
- Collaborate to plan, test, improve, and reflect on a design under constraints
-
Real-world STEAM Connection and Problem definition
- Connection (student perspective):
Engineers and architects build strong structures with limited materials. They have to look closely at models, plan carefully, test ideas, fix failures, and avoid wasting resources.
- Problem definition (student perspective):
“How can our team use limited spaghetti and marshmallows to build a stable rectangular pyramid with a 4×3 rectangular base that matches the teacher’s model, while using materials wisely and learning to describe what we see with geometry words?”
-
Materials at a Glance
- Tablets/LMS access (optional in-class replay of videos if needed)
- Exit-ticket printouts (from flipped videos)
- 3 prebuilt rectangular pyramid models (4×3 rectangular base) visible at each table
- Dry spaghetti sticks (limited supply per team)
- Marshmallows (limited supply per team)
- Chart paper and markers (team plan + notes)
- Timer/stopwatch
- Constraint sheet (resource limits + waste minimization prompt)
- Quick observation checklist sheets (points/lines/parallel/angles)
-
Indoor/Outdoor and Classroom layout
Indoor
- Tables arranged in pods (4–6 students per team)
- One model pyramid per pod (or 3 models distributed across the room)
- Whiteboard/chart area for whole-class question + final reflection
- “Materials station” with pre-measured team packs (to support fairness and stewardship)
-
Notes on Research-based approach and integration
Students arrive with baseline concept input from short videos (flipped classroom), freeing class time for hands-on investigation, building, and iteration. They begin by observing a real model and identifying geometric features (research), then create and test a prototype under constraints (design), and finally compare results and reflect on both strategies and resource use (connect). The two-trial structure plus peer “snowball” exchange mirrors real engineering cycles: observe → plan → test → learn → improve.

- “How did you use materials wisely?”
Stage Debriefing Questions (Optional)
- “What would you do first if you built it again tomorrow?”
Tips and Tricks for dealing with stage challenges
- Challenge: Students only say, “ours is better/worse.”
- Tip: Require one “because” sentence with evidence: “It leaned because…”
- Challenge: Some students don’t want to mention mistakes.
- Tip: Normalize: “Mistakes are data.” Ask for “one lesson learned” rather than “one failure.”
-
-
Tips and Tricks for dealing with challenges (for the whole STEAM program)
- Normalize failure: “Engineers expect breaks and rebuilds—that’s normal. ”Use the mantra Break → Breathe → Rebuild.
- Use a visible timer with checkpoints (“Half time—check your base!”).
- Encourage reuse: broken spaghetti pieces can become braces/supports.
- If teams get stuck, ask: “What is the smallest change you can test next?”
- Make stewardship visible: each team keeps a “reuse pile” and “waste corner
- Noise/chaos: Use a quick signal (“Scientist hands!”) for freeze + reset.
- Unequal participation: Role cards + rotate roles between Trial 1 and Trial 2.

Difficulty level tailoring notes
A) Grade-level tailoring (content depth)
- Grade 3 (Core):
- Identify pyramid names by the base shape
- Find points/lines/parallel lines/angles using a guided checklist
- Build for stability and match the model “as close as possible”
- Grade 4 (Extension):
- Count faces/edges/vertices and compare to the model
- Classify angles more explicitly (right/acute/obtuse) using a reference chart
- Add a simple “stability score” (stands 10 seconds = success)
- Grade 5 (Extension):
- Add an “efficiency score” (stable structure + minimal waste)
- Require claim–evidence reasoning: “We changed X because Y happened.”
- Explore the scaling question: “What changes if the base becomes 5×4?”
B) Skill-level tailoring (same task, different scaffolds)

- Flexibility
- Beginner learners: Provide a “Try next” menu (shorten edge / rebuild base / add brace / swap roles).
- Intermediate learners: Adopt one peer suggestion from snowball exchange and explain why it fits.
- Advanced learners: Evaluate two suggestions, reject one with a reason, implement the best.
- Resilience
- Beginner learners: Class mantra: “Break → breathe → rebuild.” Assign a “reset role.”
