Activity 01
Design Challenge: Physics Solution Proposal
Small groups select a real-world problem from a teacher-curated list (or propose their own) and produce a written proposal that identifies the relevant physics principles, sketches a solution, lists key design constraints, and specifies how success would be measured. Groups exchange proposals for peer review before moving to the build or modeling phase.
How can we use physics to design a more sustainable city?
Facilitation TipDuring Design Challenge: Physics Solution Proposal, require each group to include a materials list with cost estimates before they proceed to prototyping, forcing early consideration of real-world limits.
What to look forStudents present their initial problem statement and proposed solution to a small group. Peers use a rubric to assess: Is the problem clearly defined? Is the proposed solution grounded in specific physics principles? Are potential constraints identified? Peers provide one specific suggestion for improvement.

Activity 02
Prototype and Test: Iterative Engineering
Groups build or model their proposed solution using available materials or simulation tools (PhET, Tinkercad, or structural analysis apps). They run at least two test iterations, recording results and identifying what the physics data tells them about necessary design changes. A structured iteration log keeps the process visible and prevents groups from skipping the analysis step.
What engineering solution can best mitigate the effects of natural disasters?
Facilitation TipDuring Prototype and Test: Iterative Engineering, provide a simple failure report template that students must complete after each test, prompting reflection on what went wrong and how to adjust.
What to look forFacilitate a whole-class discussion using the prompt: 'Which real-world problem discussed today would be most challenging to solve using only physics principles, and why? What other scientific disciplines would be essential?'

Activity 03
Peer Critique: Engineering Design Review
Each group presents their project in a structured 'design review' format: 5 minutes presenting the problem, physics analysis, and proposed solution, followed by 5 minutes of structured peer questions. Peer reviewers use a rubric that evaluates accuracy of physics content, quality of evidence, and realistic assessment of tradeoffs. Written peer feedback is submitted before each group's final revision.
How does physics bridge the gap between imagination and reality?
Facilitation TipDuring Peer Critique: Engineering Design Review, use a round-robin format so every student gives and receives feedback, ensuring all voices contribute to improvement.
What to look forAs students begin their project, ask them to submit a brief 'Problem Statement and Physics Connection' form. This form should ask: 1. What is the real-world problem you are addressing? 2. What specific physics concepts will you use to analyze or solve it? 3. What is one potential constraint you anticipate?

Activity 04
Final Presentation: Physics in Action Showcase
Groups present completed projects to an audience that includes at least one outside evaluator (another teacher, a community member, or a local engineer). Presentations include a visual display, a demonstration or simulation, and a 3-minute summary. Each student individually answers one physics content question from the evaluator to confirm individual understanding within the team project.
How can we use physics to design a more sustainable city?
Facilitation TipDuring Final Presentation: Physics in Action Showcase, set a strict time limit for each presentation to mirror real-world constraints and keep the focus on clarity and impact.

Generate Complete Lesson→A few notes on teaching this unit
Experienced teachers treat this capstone like a scientific research group, not a traditional end-of-year test. Model iterative problem-solving by sharing your own design struggles and revisions. Avoid giving answers; instead, ask guiding questions that push students to connect principles to their project. Research shows students benefit most when they experience failure as data, not as a mark of incompetence.
Successful students will present a solution that is physically sound, feasible within stated constraints, and clearly communicated to an audience. They will demonstrate their ability to integrate multiple physics domains and justify design choices with evidence and reasoning.
Watch Out for These Misconceptions
During Design Challenge: Physics Solution Proposal, watch for students who propose solutions that ignore cost, safety, or local availability of materials.
At the proposal stage, require students to complete a constraint matrix worksheet listing at least three real constraints and explain how their design addresses each one before approval to build.
During Prototype and Test: Iterative Engineering, watch for students who blame the prototype itself rather than the physics or design when it fails.
After each test, have students write a short reflection that explicitly links the failure to a specific physics principle or design assumption, not just material weakness.
During Final Presentation: Physics in Action Showcase, watch for audiences assuming a flashy but unphysical solution is superior.
Include a section in the rubric for 'Physics Integrity' that assesses how accurately and thoroughly physics principles are applied, ensuring the solution is evaluated on merit, not just aesthetics.
