Introduction
🍎 Welcome, Young Scientists!
Have you ever wondered what happens to food after you eat it? How does your body turn food into energy?
The digestive system is a group of organs that work together to break down food, absorb nutrients, and remove waste.
In this WebQuest, you will become a young scientist and explore the amazing journey of food inside the human body.
Are you ready to discover how your digestive system works? Let the adventure begin!
Task
🎯 Your Mission: Become a Digestive System Explorer!
Work in groups of four to five students to investigate the human digestive system using the provided online resources.
Your task is to create a "5–8-slide digital presentation" that includes:
1. A labeled diagram of the digestive system.
2. The major digestive organs and their functions.
3. The journey of food through the body.
4. The processes of digestion and nutrient absorption.
5. The functions of the liver, pancreas, and gallbladder.
6. Three healthy habits that support digestion.
Use pictures, simple explanations, and creative designs to make your presentation interesting.
Final Output: A group presentation lasting 5–7 minutes.
Process
🧭 Follow These Steps to Complete Your Mission!
Step 1: Form Your Team 👥️
Organize yourselves into groups of four to five members and assign responsibilities.
Step 2: Explore🔍
Visit the provided websites and learn about the digestive organs and their functions.
Step 3: Investigate🕵♀️
Answer these questions:
- Where does digestion begin?
- What happens to food in the stomach?
- Where are nutrients absorbed?
- What happens to undigested food?
- How do the liver and pancreas help digestion?
Step 4: Discover Healthy Habits🏃♀️
Identify three ways to maintain a healthy digestive system, such as eating nutritious food, drinking enough water, and exercising regularly.
Step 5: Create Your Presentation👩🏫
Prepare your 5–8-slide presentation using Canva, PowerPoint, or Google Slides. Include illustrations and reliable information.
Step 6: Share Your Findings💡
Present your work to the class. Make sure every member participates.
Step 7: Reflect📝
Write a short reflection about what you learned and how you can apply it to your daily life.
