Introduction
Have you ever wondered why the sea level rises and falls every day? Fishermen, surfers, and even animals rely on tides for survival. In this WebQuest, you will become a scientific explorer to discover how the Moon and Sun control the ocean’s movement, and why tides are important to our world.
Task
Your mission is to create a digital presentation (Google Slides/PowerPoint) that explains:
-
What causes ocean tides.
-
The different types of tides (high tide, low tide, spring tide, neap tide).
-
How tides affect human activities (fishing, shipping, coastal communities).
-
A creative illustration (diagram or drawing) showing how the Moon and Sun affect tides.
Process
Follow these steps to complete your task:
-
Read and Watch the resources provided below.
-
Take notes on key concepts about causes, types, and effects of tides.
-
Work with your group (or individually if assigned) to organize your notes into sections.
-
Create a slide presentation with text, images, and diagrams.
-
Present your work to the class, explaining your findings clearly.
