ExperimentThe Engineering Design Process
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
- experiment
- data
- observation
Materials Needed
- pennies
- plastic wrap
- cardboard
- tape
- scissors
- straws
Safety First
- Keep small objects away from young children.

Steps
Step 1 — Read
Study the diagram and label the parts you recognize.
Step 2 — Do

Step 3 — Observe
Draw a detailed diagram of what you observe.
Step 4 — Record
Write a conclusion: what did your results show? Did they match your prediction?
