Building Showcased Solutions

Overview

Students finalize their STEM projects, practice presenting to an audience, and reflect on what they built and how they worked together. The lesson ends with a short showcase and a structured reflection on planning, testing, and improvement.

Learning intentions

• Students will be able to complete a build/design to meet an agreed-upon goal.
• Students will be able to explain how their solution works using science/engineering ideas.
• Students will be able to present their project clearly and respond respectfully to questions.
• Students will be able to reflect on teamwork, changes made, and lessons learned.

Success criteria

• I can finish my project and ensure it meets the requirements from our planning notes.
• I can describe the parts of my solution and how it solves the problem.
• I can share my presentation with an audience and answer questions.
• I can write or record a reflection using evidence from my testing and revisions.

Curriculum links

• Science and Engineering Practices: building, testing, revising, and communicating explanations.
• CCSS Writing: producing clear, organized informational writing and using facts to support ideas.
• CCSS Speaking and Listening: presenting information and ideas clearly; participating in discussions.
• CCSS Math (if measurement is used): applying measurement skills and interpreting results.

Lesson structure (240 minutes)

1. 0–20 min | Warm start + success checklist

• Review the unit “goal statement,” project requirements, and the final-day showcase plan.
• Students choose one “must-finish” item and one “polish” item for their project.

2. 20–90 min | Final build and test rounds

• Students complete construction and run at least one quick test (e.g., try, observe, record results).
• If the solution doesn’t meet the goal, students make one targeted revision (change one variable/part, then retest).

3. 90–115 min | Presentation preparation

• Students outline a simple presentation plan: Problem → My design → How it works → Test results → Improvements.
• Students create a label set or poster notes (main parts + one diagram or step sequence).

4. 115–155 min | Presentation rehearsal with feedback

• In small turns, each student practices delivering their explanation while the other uses a “kind, specific feedback” prompt:
• What is clear?
• What should be explained more?
• What evidence from testing supports the claim?
• Students revise their script or poster based on feedback.

5. 155–200 min | Showcase presentations

• Students present to peers (or family/another group if available) using their prepared outline.
• After each presentation, students ask and answer at least 1 question using complete sentences and respectful discussion habits.

6. 200–230 min | Reflection: evidence-based journal

• Students complete a short reflection:
• What was my goal?
• What did I test?
• What changed after testing?
• What worked well in our teamwork?
• Students include one “evidence sentence” (a result they observed or measured).

7. 230–240 min | Close-out routine

• Students share one final takeaway and one gratitude statement about teamwork.
• Teacher/parent collects project artifacts (poster, testing notes, reflection).

Resources

• Project planning notes from Lesson 1–9 (goal, constraints, diagram drafts)
• Materials needed to finalize builds (cardboard/foam, tape/glue, fasteners, rulers, markers)
• Simple testing tools (timers, measuring tapes/rulers, funnels/cups, paper meters—match the project type)
• Student “presentation outline” sheet and reflection journal page
• Poster paper or display boards; sticky notes for labels
• Timer for rehearsal and turn-taking
• Peer feedback prompt card (clear/unclear; evidence; suggestion)
• Safety reminders for materials and tools used

Assessment

• Project completion: checklist evidence that requirements were met and revisions were made after testing.
• Communication: teacher listens for a clear sequence (problem → design → explanation → results).
• Reflection quality: students use observed evidence to justify improvements and identify teamwork contributions.

Differentiation

• For early support: provide a sentence starter bank for explanations and reflections (e.g., “My design works because…” “I tested it by…”).
• For hands-on learners: assign a “materials manager” role to keep building active while the other drafts labels and script.
• For advanced learners: require additional reasoning—include why one change improved performance and compare results before/after.
• For EAL/SEN supports: allow responses using drawings plus short oral explanations; provide a reduced checklist (fewer requirements, same goal). Encourage practicing one question-and-answer exchange before the showcase.
