Understanding Ocean Tides

Introduction

Have you ever wondered why the water at the beach sometimes rises and sometimes falls? Ocean tides are a fascinating natural phenomenon caused by the gravitational pull of the Moon and the Sun. In this WebQuest, you will explore how tides work and why they are important to our planet and coastal communities.

Task

Your task is to work in small groups to research ocean tides and create a short digital presentation (PowerPoint, Google Slides, or poster) explaining:

  • What ocean tides are
  • The role of the Moon and the Sun in causing tides
  • The difference between high tide and low tide
  • Why tides are important for people and marine life

At the end of the activity, your group will present your findings to the class.

Process
  1. Form a group of 3–4 students.
  2. Read the provided resources about ocean tides.
  3. Discuss with your group how the Moon and Sun affect tides.
  4. Create a simple presentation explaining the key concepts.
  5. Add diagrams or images to make your presentation clear.
  6. Present your work to the class and answer questions.
