Introduction
Have you ever noticed that the sea level changes throughout the day? Sometimes the water reaches far up the shore, while at other times it moves far back. These changes are called ocean tides, and they affect fishing, shipping, coastal communities, and marine life.
In this WebQuest, you will become a junior ocean scientist tasked with discovering what causes ocean tides and why they change. Using online resources, videos, and simulations, you will investigate how the Moon and the Sun influence Earth’s oceans.
Task
Your task is to create a digital poster or slideshow presentation that explains:
-
What ocean tides are
-
The role of the Moon and the Sun in creating tides
-
The difference between high tide and low tide
-
The difference between spring tides and neap tides
Your final output will be presented to the class and should clearly explain the concepts using diagrams, images, and your own words.
Process
Follow these steps to complete the WebQuest:
-
Form a group of 3-4 members.
-
Watch and read the provided online resources about ocean tides.
-
Take notes on:
-
Definition of ocean tides
-
Gravitational pull of the Moon and Sun
-
Types of tides
-
-
Discuss your findings with your group members.
-
Create your output (digital poster or slideshow) using PowerPoint, Google Slides, or similar tools.
-
Prepare a short explanation (2-3 minutes) to present your work.
-
Submit and present your final output to the class.

Conclusion
Congratulations! You have successfully explored how ocean tides work and why they are important. Through this activity, you learned how scientific concepts can be understood using online resources and teamwork. Reflect on how the Moon and the Sun affect our daily lives more than we often realize.
As future scientists and responsible citizens, understanding natural phenomena like tides helps us appreciate and protect our environment.
