Aim:
To create a simple, low-cost version of your idea and learn from testing it.
Requirements:
-
Cardboard or paper
-
Scissors, glue, tape
-
Sketch of your design idea
-
Friend or classmate to test it
Steps:
-
Look at your sketch from Lesson 3.
-
Make small improvements or changes based on what you learned.
-
Use materials like cardboard to build a basic version (prototype).
-
Ask someone to test or try using it.
-
Observe carefully—what works? What doesn’t?
-
Write down your findings.
-
Make changes and test again!
Working:
Students gain hands-on experience with creating and testing. They learn that feedback leads to better versions of their design.
