Introduction
Have you ever wondered why the ocean water rises and falls throughout the day? Coastal communities depend on tides for fishing, transportation, and recreation. In this WebQuest, you will become a junior marine scientist and investigate the causes and effects of ocean tides. By exploring online resources, you will discover how the Moon and the Sun influence Earth's oceans and why understanding tides is important in everyday life.
Task
Your mission is to create a digital presentation or infographic explaining:
- What ocean tides are.
- The causes of tides.
- The different types of tides.
- The importance of tides to people and the environment.
Your final product should include:
- Definitions and explanations
- Diagrams or images
- At least three interesting facts about tides
- A real-world example showing the importance of tides
Process
Step 1: Learn About Ocean Tides
Read and watch the resources provided.
Step 2: Answer the Guide Questions
- What are tides?
- What causes tides?
- What are spring tides and neap tides?
- How do tides affect human activities?
Step 3: Organize Information
Create a concept map or outline showing the relationship between the Moon, Sun, Earth, and tides.
Step 4: Create Your Final Product
Develop a PowerPoint presentation, Canva infographic, or Google Slides presentation.
Step 5: Share and Reflect
Present your work to the class and explain one new thing you learned about tides.
Evaluation
Since your assignment requires you to create and submit a WebQuest link, I cannot generate the actual link for you because it must be created under your account on CreateWebQuest. However, I can provide a complete WebQuest that you can copy and paste into the website.
