Introduction
Have you ever wondered why the ocean seems to “breathe,” rising and falling each day? These movements, called tides, are more than just waves — they are powerful forces shaped by the moon, the sun, and Earth’s rotation. In this WebQuest, you’ll become oceanographers-in-training, uncovering the mysteries of tides and their impact on human life.
Task
Your mission is to create a multimedia presentation (Google Slides, PowerPoint, or Canva) explaining:
-
What causes tides
-
The difference between high tide, low tide, spring tide, and neap tide
-
How tides affect human activities (fishing, shipping, coastal living)
Your final product should include visuals, diagrams, and at least one real-world example of tides influencing daily life.
