Exploring the Ocean Tides

Introduction

Have you ever wondered why the sea level rises and falls throughout the day? Why some beaches have huge waves in the morning but calm waters at night? In this WebQuest, you will become young oceanographers as you explore the mystery behind ocean tides. Using online resources, multimedia, and data charts, you will discover how the moon, sun, and Earth work together to create one of nature’s most fascinating daily events.

Task

Your task is to create a digital mini-presentation (Google Slides, PowerPoint, or Canva) explaining the following:

  1. What causes tides?

  2. What are high tides and low tides?

  3. What are spring tides and neap tides?

  4. How tides affect people, animals, and coastal communities.

Your final output will be presented to the class as if you are “Tide Experts” giving a short scientific report.

Process

Follow these steps:

Step 1: Learn the Basics

Watch the assigned videos and read the web articles to understand how tides work.

Step 2: Take Notes

Write short notes or highlight key ideas about:

  • Gravity

  • Moon–Earth interaction

  • Sun’s influence

  • Tide cycles

Step 3: Analyze Tide Charts

Choose one tide chart from the resources and interpret when high and low tides occur.

Step 4: Create Your Presentation

Your presentation must include:

  • Clear definitions

  • Diagrams or pictures

  • A simple explanation in your own words

  • One real-life example (fishing, boating, beach safety, marine life, etc.)

Step 5: Submit and Present

Upload your presentation to your LMS or present it in class.
