Introduction
Have you ever noticed that the sea level changes throughout the day? Sometimes the water comes closer to shore, and other times it moves farther away. These changes are called ocean tides, and they affect fishing, navigation, marine life, and coastal communities.
In this WebQuest, you will become a junior marine scientist tasked with discovering what causes ocean tides and why they follow predictable patterns. By exploring reliable online resources, you will uncover how the Moon, Sun, and Earth work together to create tides.
Task
Your task is to work in a small group to create an informative digital poster or slide presentation that explains:
What ocean tides are:
1. The role of the Moon and the Sun in creating tides
2. The difference between high tide and low tide
3. The difference between spring tides and neap tides
4. Why tides are important to people and marine life
Your final product will be presented to the class.
Process
Follow these steps to complete your WebQuest:
1. Form a group of 3–4 students.
2. Assign roles (researcher, note-taker, designer, presenter).
3. Visit the provided web resources to gather information about ocean tides.
4. Take notes and summarize information in your own words.
5. Organize your findings into a digital poster or slide presentation.
6. Include at least one diagram or image (with proper credit).
7. Review your work using the rubric before submission.
8. Present your project to the class.
