Introduction
Have you ever wondered why the level of ocean water rises and falls? These regular changes are called ocean tides. The Moon, the Sun, and the Earth interact through gravity, causing changes in the ocean's water level.
In this WebQuest, you will become a young ocean scientist. You will explore reliable websites and online resources to discover how tides occur, what causes them, and why understanding tides is important to people living near coastal areas.
Task
Your task is to investigate the causes and effects of ocean tides and create a digital infographic or short presentation explaining what you have learned.
Your final output should include:
- Definition of ocean tides
- Causes of tides
- Role of the Moon and Sun
- Difference between high tide and low tide
- Importance of understanding tides
- At least one diagram or illustration
You will present your work to the class.
Process
Follow these steps:
- Form a group of 3–4 students.
- Research what ocean tides are using the provided online resources.
- Identify the roles of the Moon, Sun, and Earth's gravity in producing tides.
- Compare high tide and low tide.
- Discuss why tides are important to fishermen, coastal communities, and marine activities.
- Organize your findings into an infographic or presentation.
- Include diagrams or illustrations to help explain the process.
- Present your final output to the class.
- After the presentation, discuss what your group learned and what questions you still have.

Conclusion
Congratulations, young ocean scientists! Through this WebQuest, you explored the causes of ocean tides and learned how the Moon, Sun, and Earth interact to influence the movement of ocean water.
Reflect on what you learned: How does understanding ocean tides help people who live and work near the ocean?Think about how the knowledge you gained can be applied to real-life situations such as fishing, navigation, coastal activities, and marine safety.
