Lesson 60 of 84 · Waves
ExperimentEngineering Constraints and Criteria (Part 3)
What You'll Learn
Engineers must consider constraints (limitations like cost, time, and materials) and criteria (requirements the solution must meet) when designing solutions to problems.
Key Words
- constraint
- criteria
Materials Needed
- paper clips
- rubber bands
- string
- cups
Safety First
- Clean up spills immediately to prevent slipping.
- Use materials only as directed in the experiment.
Steps
Step 1 — Read
Read about Waves and write down three key facts.
Step 2 — Do
Conduct a design challenge: build a car powered only by a balloon. Measure how far it travels and iterate on your design at least twice.
Step 3 — Observe
Watch carefully for any changes and note the time.
Step 4 — Record
Create a data table to organize your measurements.
