Introduction
Have you ever visited a beach and noticed that the water level changes throughout the day? Sometimes the water comes closer to shore, while at other times it moves farther away. These changes are called tides. As young scientists, you have been invited to investigate why tides occur and how the Moon and the Sun affect the oceans on Earth.
Your mission is to discover the science behind ocean tides and share your findings with others.
Task
You will work as a marine science researcher. Your task is to create a digital presentation, infographic, or poster that explains:
- What ocean tides are.
- The difference between high tide and low tide.
- How the Moon's and Sun's gravity affect tides.
- Why tides are important to people, marine life, and coastal communities.
Your final product should be informative, visually appealing, and based on information gathered from the provided resources.
Process
Step 1: Learn About Tides
Read and watch the resources provided by your teacher.
Step 2: Take Notes
Answer the following questions:
- What is a tide?
- What causes tides?
- What is the difference between high tide and low tide?
- How does the Moon affect tides?
- How does the Sun affect tides?
Step 3: Research Real-Life Importance
Investigate how tides affect:
- Fishermen
- Marine animals
- Coastal communities
- Shipping and transportation
Step 4: Create Your Project
Create one of the following:
- PowerPoint Presentation
- Canva Infographic
- Educational Poster
Step 5: Present Your Findings
Present your project to the class and explain your conclusions.

Conclusion
Congratulations, Marine Scientists!
You have discovered how the Moon and the Sun work together to create ocean tides. Through your research, you learned that tides play an important role in nature and in the lives of people who depend on the ocean. Think about this question: How would life on Earth be different if ocean tides did not exist?
Reflect on what you learned and how scientific investigation helped you understand a natural phenomenon that affects our planet every day.
