Introduction
Have you ever wondered why the sea sometimes moves closer to the shore and at other times seems to pull away? Every day, oceans around the world rise and fall in a steady rhythm known as tides. These movements affect marine life, fishing, coastal communities, and even weather patterns. In this WebQuest, you will act as a junior ocean scientist and investigate what causes ocean tides and how the Moon and the Sun influence Earth’s oceans.
By the end of this activity, you will understand that tides are not random—they follow predictable patterns driven by forces beyond our planet.
Task
Your task is to create a digital infographic or short presentation that explains:
-
What ocean tides are
-
The difference between high tide and low tide
-
How the Moon and the Sun affect tides
-
The difference between spring tides and neap tides
Your final product should be clear, visually engaging, and easy for other students to understand.
Process
-
Form a group of 3–4 students.
-
Review the provided online resources about ocean tides.
-
Take notes on key concepts, especially the role of gravity.
-
Discuss your findings with your group and organize the information.
-
Create your infographic or presentation using tools such as PowerPoint, Canva, or Google Slides.
-
Make sure your work includes images, labels, and short explanations.
-
Review your output for accuracy and clarity.
-
Submit your final output and be ready to present it to the class.
Evaluation
Your work will be evaluated using the rubric below:
| Criteria | Excellent (4) | Good (3) | Fair (2) | Needs Improvement (1) |
|---|---|---|---|---|

| Visual Presentation | Very creative and well-organized | Organized | Some organization | Poor organization |
| Teamwork | All members contributed equally | Most contributed | Uneven participation | Minimal participation |
Conclusion
Congratulations! You have completed your journey as a junior ocean scientist. Through this WebQuest, you explored how gravitational forces shape the movement of Earth’s oceans and learned that tides are a result of the dynamic relationship between the Earth, Moon, and Sun. More importantly, you practiced researching, collaborating, and explaining scientific ideas in your own words. Understanding tides helps us better appreciate how interconnected our planet is with the universe.
