Introduction
Have you ever wondered why the sea rises and falls every day? Or how ocean tides affect marine life, fishing, and coastal communities?
In this WebQuest, you will become a Marine Science Explorer tasked with understanding ocean tides and their importance to ecosystems and humans. You will investigate how tides work and create a simple educational output to help others learn about them.
Task
Your mission is to create an informative poster or short digital presentation that explains:
- What ocean tides are
- How tides are formed (gravity of the moon and sun)
- Types of tides (high tide, low tide, spring tide, neap tide)
- How tides affect marine life and human activities
Your final output will be presented to the class as teaching material for younger students (Grade 5–6 level).
Process
- Watch an introductory video about ocean tides.
- Read the provided online resources about how tides are formed.
- Take notes on key concepts (definition, causes, types, effects).
- Answer guiding questions:
- Why do tides happen twice a day?
- How does the moon affect tides?
- Why are tides important to fishermen and coastal communities?
- Create your output:
- Poster (handmade or digital) OR
- PowerPoint/Canva presentation
- Prepare a short 2–3 minute explanation to present your work.
