Technological Design Process

Key Questions to Ponder:

  • What is the need to be fulfilled?
  • Can I improve an existing object?


Suggest an explanation

My Idea: I explain in my own words what I know about the need to be fulfilled or the object to be improved.

My possible solution: I imagine my prototype… I imagine the operation principle… I use words and sketches to illustrate my idea.

Plan and produce a prototype

Materials: I list what materials I will need to build my prototype and find out if the materials, tools, and equipment are readily available?


  • I choose the materials to produce the prototype and then proceed to the following questions:
    • What are the main parts to be made?
    • How will I assemble my prototype?
    • What are the appropriate techniques?
    • What precautions do I need to take?
    • What should I note and when?


  • I create the prototype according to my plan.
  • I adjust the plan as needed and note the adjustments.
  • I preform tests to check the prototype.

Working out explanations and concluding

Working out explanations and concluding

  • I evaluate my prototype based on the characteristics in my plan.
  • I communicate how I have solved the problem using the correct scientific terminology.
  • Did I use the right terms and respect the rules and conventions to express my idea?
  • I describe what I learned from this activity.
