ExperimentThe Engineering Design Process (Part 3)
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
Materials Needed
- straws
- paper clips
- rubber bands

Safety First
- Be careful with scissors — ask an adult for help if needed.
- Do not look directly at the sun or bright lights.
- Clean up spills immediately to prevent slipping.
