Angles

• Cold-open on the concrete hook from the primary reference — Practical Engineering leads with a scene, not a definition dump
• Make the mechanism explicit with one visual beat: looks today. Nearly every major city across the globe is located on a waterway accessible …
• Contrast or scale-up using the second reference (TED-Ed): Then water from above is allowed to fill the lock. This is usually done through a smaller …
• Close on what the viewer can check themselves; original narration only — do not copy reference wording

Beat-by-beat structure

1. Hook (0:00–0:30): open on the puzzle of 'Panama Canal locks' in one image.
2. Setup (0:30–2:00): define the key terms in plain words; borrow structure from Practical Engineering, not lines.
3. Mechanism (2:00–5:00): walk the cause-and-effect with one diagram; cite the evidence beat (looks today. Nearly every major city across the globe is located on a …).
4. Contrast (5:00–7:00): show the common myth or the second case from TED-Ed.
