Class: Inventions & Innovations
Project: Invent Something That Solves a Real-World Problem
Your challenge is to identify a real problem, invent a solution, and build a prototype. You will work in teams and follow the Design Process from start to finish. Your final project includes:
A slide deck showing each step of the Design Process
A prototype made from classroom materials, 3D-printed parts, Glowforge-cut pieces, or a combination
A short presentation to the class
Design Process Steps (You Must Complete All 9)
Choose a real problem that affects you, your school, or your community.
Explain who has this problem and why it matters.
Write a clear problem statement.
Slide Requirement: One slide explaining the problem.
Look up how others have tried to solve this problem.
Learn about useful materials, tools, or designs.
Collect notes or screenshots for your slide.
Slide Requirement: One slide summarizing what you learned.
Create at least 10 different ideas—even wild ones!
Discuss your ideas as a team.
Slide Requirement: One slide showing your list of possible solutions.
Think about criteria and constraints:
Is it safe?
Can it be built with the materials we have?
Will it actually solve the problem?
Select the best idea using a decision matrix or team vote.
Slide Requirement: One slide explaining why you chose your final design.
Draw detailed sketches from at least 2 angles.
Label important parts and materials.
Decide what parts (if any) you want to:
3D print
Laser cut with the Glowforge
Build with cardboard, wood, or craft materials
Show measurements if you know them.
Slide Requirement: 1–2 slides with sketches and plans.
Use the materials provided to create your first working model.
Your prototype does not need to look perfect.
Focus on making it function!
Slide Requirement: 1 slide with build photos and notes.
Try out your prototype.
Record what happens:
What worked well?
What didn’t work?
What surprised you?
Slide Requirement: One slide showing test results.
Make at least one improvement to your design.
Build Version 2 (if time allows).
Explain how your changes made the design better.
Slide Requirement: One slide describing improvements.
Create a final slide deck that includes all steps.
Present your invention to the class.
Show your prototype, describe your problem, and explain your design journey.
Slide Requirement: Final presentation with all steps in order.
You will have access to:
Cardboard, tape, glue, rubber bands, straws, craft sticks
Scissors, rulers, markers, hot glue
3D printers
Glowforge laser cutter
Computers for research and slide creation
Teams must have 2–3 students.
Everyone must have a job.
Use tools safely and clean your workspace.
All team members must help with the slide deck and prototype.
✔ Completed slide deck with all 9 design process steps
✔ Working prototype
✔ 3–5 minute team presentation
Think creatively—your invention does NOT need to exist already.
Keep your problem simple and clear.
Build fast and improve often.
Document everything—photos, sketches, notes.
Have fun inventing!
