What You'll Learn

Engineers use the design process to solve problems: identify the problem, research, brainstorm solutions, build a prototype, test it, evaluate results, and improve the design.

Key Words

  • data
  • observation
  • experiment

Steps

Step 1 โ€” Read

Study the diagram and label the parts you recognize.
