Introduction
INTRODUCTION
Have you ever stood by Manila Bay and wondered: Why does the water creep up the shore then pull back again, like a giant breathing? Sometimes it rises much higher than usual—what makes that happen? You are about to become a Tide Investigator! You will use online resources to unlock how the Moon, Sun, and Earth work together to create tides, and why understanding them matters for Filipino fishermen, sailors, and coastal communities.
Task
TASK
Working in small groups, you will:
1. Explain what causes daily and monthly tide patterns
2. Compare spring tides and neap tides
3. Show how tides affect life here in the Philippines
4. Create a Tide Guide Poster or Digital Infographic with clear diagrams, facts, and 3 real‑world examples. Your work will be displayed to teach classmates about tides.
Process
PROCESS
Follow these steps:
1. Learn the basics – Visit the resources below to define tides, identify what causes them, and which body has the stronger pull.
2. Spot the patterns – Explore how alignment of Earth‑Moon‑Sun changes tides; note when spring and neap tides happen.
3. Check local tides – Look up Manila Bay or your nearest coast’s tide times for this week.
4. Connect to real life – List 3 ways tides affect people like fishing, boat travel, safety, or energy.
5. Create your output – Organize facts, draw or copy simple diagrams, and design your poster/infographic.
6. Review – Use the rubric before submitting.
Evaluation
EVALUATION
Your work will be graded out of 20 points, based on these standards:
1. Scientific Accuracy (6 points)
• 5–6 points: You clearly and correctly explain what causes tides, how gravity and Earth’s rotation work together, and accurately describe spring and neap tides with no errors.
• 3–4 points: Most facts are correct, but some details or explanations are missing or slightly unclear.
• 1–2 points: Several important facts are incorrect or key ideas are missing.
2. Comparison & Understanding (5 points)
• 4–5 points: You clearly explain the differences between spring and neap tides, including when and why each happens.
• 2–3 points: You mention the differences but do not fully explain why or when they occur.
• 1 point: You cannot tell the difference between the two types of tides.
3. Real‑World Connection (5 points)
• 4–5 points: You give at least 3 specific, relevant examples of how tides affect people and communities in the Philippines.
• 2–3 points: You give 1–2 examples that are somewhat related but not detailed or local.
• 1 point: You give no examples or examples that are not related.
4. Presentation & Clarity (4 points)
• 3–4 points: Your work is neat, easy to understand, well‑organized, and uses simple diagrams or labels that help explain your ideas.
• 1–2 points: It is readable but could be better organized or clearer.
• 0 points: It is messy, hard to read, or confusing.
Conclusion
CONCLUSION
You have discovered that tides are not random—they follow predictable rules of gravity and motion! You now know why tides change, how they shape life along our coasts, and how science helps us prepare for them. Take a moment to reflect: How would my day be different if I lived and worked by the sea? What else would I want to find out about our oceans?
