Introduction
In this WebQuest, you will learn about ocean tides and the science behind them. You will explore how the gravitational pull of the moon and sun affect the tides on Earth. You will also discover the different types of tides—spring and neap tides—and how they impact our daily lives. Let’s dive into the science of tides and explore the forces at work!
Task
Your task is to investigate and explain the causes of ocean tides. After conducting research, you will create an informative presentation to share with your classmates. This presentation should include:
- A description of how the moon and sun affect tides.
- A comparison of spring tides and neap tides.
- Real-life examples of where and when these tides occur.
Process
- Step 1: Visit the resources provided to learn about ocean tides and their causes.
- Step 2: Watch a short video on how the moon’s gravity causes tides.
- Step 3: Research the differences between spring and neap tides using the websites provided.
- Step 4: Create a PowerPoint presentation or a simple report summarizing your findings.
- Step 5: Share your presentation with the class or submit it as directed.

Conclusion
Great job exploring the fascinating world of ocean tides! By now, you should have a solid understanding of how the moon, sun, and Earth interact to cause tides. You also explored the impact of spring and neap tides and how they affect coastal areas. Think about how understanding these natural processes might help us predict and manage real-world challenges like flooding or coastal erosion.
