Introduction
Have you ever wondered why the sea rises and falls throughout the day? These fluctuations, known as tides, are a fascinating natural phenomenon caused by the gravitational pull of the Moon and the Sun. In this WebQuest, you will become a "Tide Investigator" as you explore how tides occur and why they are important to both people and the environment.
Task
Your task is to:
- Research how tides work and what causes them.
- Create a group presentation (poster, slide deck, or infographic) explaining the types of tides and their effects on coastal communities.
- Reflect on why understanding tides is important for people who live near the ocean.
The final product will be presented to the class and graded using the rubrics provided.
Process
- Form groups of 3 to 5 members.
- Read and explore the provided resources to gather information about tides.
- Organize your findings:
- Definition of tides
- Causes of tides (Moon, Sun, Earth's rotation)
- Types of tides (high, low, spring, neap)
- Real-life effects of tides (fishing, transportation, coastal living)
- Create your group's final output (poster, infographic, or slides).
- Prepare a short reflection on what you learned about tides.

This WebQuest is designed for Grade 8 Science students under the unit Earth and Space Science. It focuses on the concept of ocean tides and their real-life applications.
Learning Objectives:
- Define and explain tides and their causes.
- Differentiate between the types of tides (high, low, spring, neap)
- Demonstrate the importance of tides in daily life and coastal communities.
- Collaborate in groups to create a visual presentation about tides.
This activity integrates inquiry-based learning and development research, collaboration, and presentation skills.
