Welcome to STEM GH Capstone Hub

Your journey from idea to prototype, simplified

01. What is the Capstone Project?

Capstone is a special subject at STEM schools where students work on real challenges instead of just studying from books. Each team follows the Engineering Design Process (EDP) to find a problem, research solutions, design, and build a prototype. At the end of the term, every team submits four main deliverables:

02. EDP Timeline

The Engineering Design Process (EDP) is a series of steps that guide teams in developing their projects. Here's a typical timeline for a Capstone project:

  1. Identify the Problem Pinpoint what needs solving and why it matters
    Example: "We must design a low-cost system that produces at least 40 joules of renewable energy using a solar chimney and vertical wind turbine"
  2. Research and Gather Information Collect scientific principles, prior solutions, and available resources
    Example: study chimney airflow mechanics, turbine efficiency, energy conversion, Arduino-based measurement, and material prices in Egypt
  3. Define Requirements and Constraints Set measurable goals and list all limits
    Example: output ≥40 joules, budget ≤1500 EGP, 6-week timeline, portable size, safe to use in school, includes Arduino monitoring system
  4. Brainstorm and Ideate Generate multiple possible designs without judgment
    Example: test different turbine blade shapes, vary chimney height, add black paint for heat absorption, consider using an external fan to increase airflow
  5. Select the Best Solution Compare ideas against criteria, then justify choice
    Example: select Savonius turbine with DC motor (easy to build, reliable torque), PEV pipe chimney (cheap and light), concrete absorber base for heat storage, Arduino sensors for display
  6. Develop and Design the Prototype Turn idea into detailed sketches, diagrams, and plans
    Example: draw base dimensions (70x70 cm), chimney radius (35 cm), turbine placement, wiring diagram (motor → diode bridge → battery → Arduino + LCD)
  7. Build the Prototype Assemble the first working model using available materials
    Example: cut wood base, cast concrete absorber, mount chimney pipe, build curved plastic turbine blades, connect motor and Arduino system
  8. Test and Evaluate Measure actual performance and compare with targets
    Example: place prototype under sun, record airflow speed, measure motor voltage and current, calculate joules produced (E = V × I × t), check stability of turbine
  9. Improve and Redesign Fix weaknesses and refine design through iterations
    Example: seal chimney gaps to prevent leaks, adjust blade curvature for higher spin, add insulation around absorber, increase chimney height if needed
  10. Finalize Solution Produce the optimized working model with reliable performance
    Example: stabilize frame, tidy wiring, make LCD data readable, ensure prototype consistently meets ≥40 joules requirement
  11. Communicate and Present Share the entire process, results, and impact
    Example: prepare poster with diagrams, energy data, and before/after improvements, demonstrate live Arduino readings, explain renewable energy potential for schools

03. Capstone Deliverables

At the end of the Capstone project, each team must submit four main deliverables that showcase their work and learning throughout the term:
