🌊 Waves Lesson – Ocean Wave Anatomy, Breakers & Tsunamis

Bring ocean waves to life in your classroom with this engaging, NGSS-aligned lesson on wave anatomy, wave motion, breaker types, rogue waves, and tsunamis.

This complete lesson helps students understand how wave energy moves through water, why waves change shape near shore, and how powerful natural events like tsunamis form and impact coastal communities.

📘 What’s Included:

✅ PowerPoint Lesson (Google Slides Compatible)

Visually engaging slides covering:

• Wave anatomy (crest, trough, wavelength, height, frequency, period)
  
• How water particles move in circular motion
  
• Wave speed formula (Wave Speed = Wavelength × Frequency)
  
• Factors affecting wave size (wind speed, fetch, depth, beach slope)
  
• Types of wind waves (capillary, breakers, swells, rogue waves)
  
• Breaker types (surging, spilling, plunging)
  
• Tsunami formation and real-world case studies (2004 & 2011 events)
  
• Built-in classroom discussion questions
  
• Exit ticket
  

🎥 Embedded Video Clips Included
Each wave type includes short, engaging video clips embedded directly into the presentation. These clips help students visualize energy transfer and wave behavior in real-world conditions.
