Section 1 — Phenomenon / Driving Question / Engineering Problem
Anchor Phenomenon:
[[Describe a real-world, observable phenomenon students will investigate or solve — e.g., "Local buildings and bridges survived a recent minor earthquake with little damage while older structures in videos showed significant shaking and collapse."]]
Driving Question:
[[How can we design and build a structure that remains stable during simulated seismic activity using limited materials?]]
Engineering Design Challenge:
Students will design, build, test, and improve a model building or bridge that can withstand a simulated earthquake (shake table or manual shaking) while meeting height, span, and material constraints. The structure must remain standing after 15 seconds of shaking and support a small load.

"I Can" Statements for Students:
1. I can identify the problem and what makes a successful bridge or building.
1. I can list constraints and criteria for my design.
1. I can draw and label a plan before building.

- Clay or modeling material for base foundations or aesthetic elements
Budget / Constraint Note: [[If applicable, e.g., "All materials must be sourced from the provided kit; no outside purchases. Total estimated cost per team under $3 if sourcing replacements."]]
Safety Materials / PPE (classroom set):

- Closed-toe shoes reminder
- No running; stable work surfaces
---
Section 4 — Safety Notes and Classroom Management
Safety Considerations:
1. Students must wear safety goggles during all testing phases.
1. Shake table or manual shaking must be performed on a stable, cleared surface away from edges.
1. No throwing of materials or horseplay around structures.
1. Report any broken craft sticks with sharp edges immediately for safe disposal.
1. Adult supervision required when using any tools (if scissors or utility knives are introduced for advanced groups).
Management / Grouping:
- Teams of 3-4 students (heterogeneous grouping recommended)
- Roles: Designer (leads sketch), Builder (assembles), Tester (runs trials and records), Communicator (presents and records data)
- Rotate roles between testing rounds
Cleanup Protocol:
Teams return unused materials to bins, disassemble or store successful models as directed, wipe tables, 2-minute warning before end of period.

Section 5 — Instructional Sequence (5E or Engineering Design Process)
Total Time: [[90 minutes]] — adjustable blocks noted.
ENGAGE (10 minutes)
1. Display phenomenon video or photo set (earthquake damage vs. resilient structures).
1. Turn-and-talk: "What do you notice? What do you wonder?"
1. Introduce driving question and challenge criteria: must stand 15+ seconds on shake table, support at least 10 pennies, use only kit materials, height or span minimum.
EXPLORE (15 minutes)
1. Teams receive materials kit and criteria/constraints handout.
1. Students explore materials, discuss what makes structures stable (wide base, triangles, cross bracing).
1. Quick teacher demo of a weak tower vs. braced structure on shake table (pre-built).
EXPLAIN (10 minutes)
1. Mini-lesson or anchor chart: forces (push, pull, shear), stability (center of mass, base width, triangulation).
1. Review engineering design process: Ask → Imagine → Plan → Create → Improve.
1. Students record initial ideas in science notebooks.
ELABORATE / BUILD & TEST (35 minutes total — two rounds)
Round 1 — Build & Initial Test (15 min build + 5 min test):
1. Teams draw labeled plan (5 min).
1. Build prototype (10 min).
1. Test on shake table: record time standing and load held. Note failure points (topple, twist, collapse).
Round 2 — Improve & Retest (10 min redesign + 5 min test):
1. Analyze data from Round 1: "What failed first? Why?"
1. Redesign with at least one targeted improvement (add brace, widen base, change joint, redistribute mass).
1. Rebuild and retest. Record new data.
EVALUATE (10 minutes)
1. Gallery walk or share-out: each team presents one improvement and the data that shows it worked.
1. Class discussion: Which design features appeared most often in successful structures?
1. Individual reflection: "What science idea helped you the most today?"
Extension / STEAM Integration Options (add 15-30 min or homework):
- Art connection: Decorate structure as a local landmark or futuristic building while preserving structural integrity.
- Math connection: Measure and graph height vs. stability time; calculate average load held across class.
- Writing: Write a "design brief" explaining the final prototype to a city engineer, including data table and recommendation.

Section 6 — Assessment and Success Criteria
Formative Checks:
- Plan sketch includes labeled parts and at least two features addressing stability.
- Data table completed for both test rounds with units.
- Evidence of iteration noted (change log or verbal explanation).
Summative / Challenge Criteria (rubric 4-point scale):
| Criteria | 4 — Exemplary | 3 — Proficient | 2 — Developing | 1 — Beginning |
|---|
| Structure stands | Stands 20+ sec + supports 15+ pennies | Stands 15+ sec + supports 10 pennies | Stands 8-14 sec or supports 5-9 | Collapses before 8 sec or <5 pennies |
| Use of design process | Detailed plan, clear data comparison, thoughtful improvement | Plan present, data recorded, at least one improvement | Partial plan or data, minimal change | No plan or no iteration |
| Explanation of science | Uses force/stability terms correctly and connects to results | Uses some science vocabulary | Limited science language | No science explanation |
| Collaboration & safety | All roles used, goggles worn, respectful testing | Most roles, safety followed | Some participation or safety lapses | Off-task or unsafe |
Exit Ticket / Reflection Prompt:
1. Name one feature you added that improved stability and why it worked (use the word "force" or "base").
1. What would you change if you had one more round and different materials?

Section 7 — Differentiation and Accessibility
Supports for Diverse Learners:
- Provide pre-cut templates or partially assembled bases for students needing fine-motor support.
- Visual step cards and sentence starters for plan and reflection.
- Partner reading of criteria sheet; audio description of phenomenon video if needed.
- Reduced material set or simplified challenge (shorter time, lower height goal) for some teams.
Extensions for Advanced / Early Finishers:
- Add variable (wind load via fan, uneven "ground").
- Introduce cost constraint and optimize design for lowest "material cost" while meeting performance.
- Research real-world examples (base isolation, tuned mass dampers) and propose one feature to add.
Technology Options:
- Use free apps or phone slow-motion video to analyze shake test failures.
- Digital design (if available): Tinkercad or paper-based CAD sketch before build.

Section 9 — Background for Teacher & Common Student Misconceptions
Key Science Concepts:
- Stability increases with wider base, lower center of mass, and triangular bracing (triangles do not deform under load like rectangles).
- Earthquakes produce shear forces; structures fail at weak joints or when mass shifts.
Common Misconceptions to Address:
- "Taller is always stronger" (counter with wide-base short towers).
- "More tape/glue = better" (counter with examples of over-constrained joints that become brittle).
- "If it didn't fall, it is perfect" (emphasize data and controlled testing; always room to improve).
Teacher Background Resources (as of 2026-06-29):
- NGSS Hub: www.nextgenscience.org (search ETS1)
- PBS Learning Media or USGS earthquake resources for phenomenon videos
- "The Science of Bridges and Dams" or similar trade books for read-aloud extensions
