Lesson Outline
Introduction (10 minutes)
- Objective: Introduce the digestive system and its purpose.
- Begin by asking, “Why do we need food?” Guide students to the concept that food gives us energy and nutrients.
- Show the Adventure Guide video, ensuring students understand the journey food takes in the digestive system.
- Briefly explain that they will use this knowledge to navigate an exciting Thanksgiving-themed escape room.
Part 1: The Digestive System Overview – The Grand Harvest Table (10 minutes)
- Objective: Identify the purpose of the digestive system.
- Discuss the main purpose of the digestive system, emphasizing how it breaks down food into nutrients.
- Highlight the role of the mouth in starting the digestive process.
- Guide students to recognize that each part of the digestive system has a unique function, like how chewing is different from the stomach’s function.
Part 2: Process of Digestion – The Path of Tastes and Textures (10 minutes)
- Objective: Describe the journey food takes through the digestive system.
- Explain how food moves from the mouth, down the esophagus, and into the stomach.
- Discuss how the stomach breaks down food further, and how this process is essential for nutrient absorption.
- Reinforce how the esophagus acts as a passageway, and the stomach prepares food for the next stages of digestion.
Part 3: Nutrient Absorption and Health – The Circle of Energy (10 minutes)
- Objective: Understand the role of nutrients and the importance of a balanced diet.
- Describe how the small intestine absorbs nutrients that the body uses for growth and energy.
- Emphasize the importance of nutrients like carbohydrates, proteins, and vitamins in keeping the body healthy.
- Conclude by explaining how the large intestine absorbs water and prepares waste for elimination.
Activity: Online Escape Room – Digestive System Discovery (15 minutes)
- Instructions: Students will enter the online escape room Digestive System Discovery: The Great Thanksgiving Feast.

- Celebrate Completion: Congratulate students on completing the Digestive System Discovery escape room. Reinforce that they now know how food fuels their body and why each part of digestion is essential for health!
Teacher Reference Guide
In this lesson, students will explore the digestive system, understanding how food is broken down into nutrients that fuel the body. This guide provides the essential information needed to introduce each part of the digestive process, helping students gain a basic understanding of digestion and the importance of nutrients.
Introduction to the Digestive System
The digestive system’s main purpose is to turn food into energy and nutrients that our bodies need to grow, repair, and stay healthy. We eat food not only for taste and enjoyment but because our bodies require energy, vitamins, and minerals to function. The digestive system works by breaking down the food we eat into smaller parts that the body can absorb and use. Each part of this system has a unique job that contributes to transforming food into usable fuel.
The Grand Harvest Table: Digestive System Overview
The journey of digestion begins in the mouth, where food is chewed into smaller pieces. This process is essential because it helps make the food easier for the body to break down further. Chewing also releases saliva, which starts breaking down certain foods right in the mouth. Once food is chewed, it moves into the esophagus, a muscular tube that connects the mouth to the stomach. The digestive system works in stages, with each stage preparing the food for the next step.
The Path of Tastes and Textures: Process of Digestion
Once food travels down the esophagus, it reaches the stomach, where it is mixed with digestive juices. These juices contain acids and enzymes that break down food even further. The stomach churns food into a thick liquid, making it easier for the body to absorb nutrients later. This process of breaking down food in the stomach is crucial, as it ensures that the nutrients can be accessed and used by the body. After the stomach, food enters the small intestine for the next part of the digestive process.
The Circle of Energy: Nutrient Absorption and Health
In the small intestine, most of the nutrients are absorbed into the bloodstream, allowing them to be transported to various parts of the body. Nutrients from carbohydrates provide energy, proteins help build and repair muscles, and vitamins and minerals keep our bodies functioning well. After the small intestine absorbs these nutrients, the remaining food matter moves into the large intestine. Here, the large intestine absorbs water, which is essential for keeping the body hydrated. The large intestine then prepares any leftover waste to leave the body.
Importance of Nutrients and a Balanced Diet
A balanced diet provides the body with the various nutrients it needs to stay healthy and active. Different food groups offer different types of nutrients: carbohydrates for energy, proteins for muscle repair, and vitamins and minerals for overall health. Water and fiber, which are found in foods like fruits and vegetables, are also important for digestion, helping food move smoothly through the system. Understanding that the body needs a variety of foods helps students see why eating a balanced diet is essential for staying healthy.
