Exploring the Mystery of Ocean Tides

Have you ever noticed that the level of seawater changes during the day? Sometimes the water moves closer to the shore, while at other times it moves farther away. This movement is called a tide. In this WebQuest, you will explore how ocean tides happen and how the Moon and the Sun affect them.

Your task is to investigate how and why ocean tides occur. At the end of the activity, you will create a one-page infographic or poster showing what ocean tides are, the difference between high tide and low tide, and how the Moon and Sun affect tides. You will also write a short explanation about why understanding tides is important.

• Read the information about ocean tides from the resources provided.
• Find out what causes ocean tides.
• Identify the difference between high tide and low tide.
• Find out how the Moon and the Sun affect tides.
• Discuss your findings with your group members.
• Organize the important information you gathered.
• Create a one-page infographic or poster using Canva, PowerPoint, or paper.
• Present your output to the class.
• Write 3–5 sentences explaining why it is important to understand ocean tides.

In this WebQuest, you learned how ocean tides occur and how the Moon and the Sun affect the movement of seawater. You also learned the difference between high tide and low tide. Through this activity, you practiced finding information, working with others, and presenting what you learned. Understanding ocean tides is important because tides can affect people, animals, fishing, transportation, and communities living near the sea.

The information and learning resources used in this WebQuest were based on educational resources about ocean tides from NOAA, NASA, and National Geographic. These resources were used to help students understand the causes and effects of ocean tides.

This WebQuest is designed for Grade 8 Science students. The main topic is Ocean Tides. The activity uses an inquiry-based approach where students explore online resources, gather information, discuss their findings, and create an infographic or poster.

Learning Objective:
At the end of the activity, students should be able to explain how the Moon and the Sun affect ocean tides and distinguish between high tide and low tide.

Suggested Time: 1–2 class sessions

Materials/Technology: Internet connection, smartphone or computer, Canva or PowerPoint, and online resources.

Teacher's Role: Guide students in finding reliable information, assist them when needed, monitor their group work, and assess their final output using the rubric provided.
