Lesson Plan: The Food Web Mission
Grade Level: Elementary
Time: 1 hour or less
Subject: Science – Food Webs
Learning Objectives
By the end of this lesson, students will:

- Identify examples of organisms in each category (producers, consumers, decomposers) within different ecosystems.
- Explain the flow of energy through an ecosystem and how different organisms are interconnected.
- Demonstrate their knowledge through an interactive escape room challenge.
Materials Needed
- Video: "Adventure Guide" (to explain key food web concepts)
- Online Escape Room: The Food Web Mission: Global Ecosystem Adventure (for engagement and assessment)
Lesson Outline
1. Introduction (10 minutes)
- Begin with a brief explanation of food webs and why they are important in understanding ecosystems.
- Show the "Adventure Guide" video that introduces the concepts of producers, consumers, and decomposers.
- Discuss with students the different ecosystems (rainforest, coral reef, and arctic tundra) and how they will explore these in the escape room.
2. Subtopic 1: Producers (10 minutes)
- Key Concept: Producers create their own energy using sunlight, which is the foundation of the food web.
- Discuss how plants like trees in the Amazon Rainforest capture sunlight through photosynthesis.
- Reinforce this concept by referring back to examples in the video.
3. Subtopic 2: Consumers (10 minutes)
- Key Concept: Consumers eat other organisms for energy.
- Explore the role of herbivores, carnivores, and omnivores in the Coral Reef ecosystem.
- Ask students to think of examples of consumers from the video and how they depend on producers.
4. Subtopic 3: Decomposers (10 minutes)
- Key Concept: Decomposers break down dead material, returning nutrients to the ecosystem.
- Explain how decomposers, such as fungi and bacteria, work in the Arctic Tundra to recycle nutrients.
- Review the importance of decomposers in keeping ecosystems balanced, as shown in the video.
5. Engagement & Assessment (20 minutes)
- Activity: Direct students to the online escape room, The Food Web Mission: Global Ecosystem Adventure.
- Explain that they must answer questions and solve challenges to advance through the rainforest, coral reef, and tundra ecosystems.
- Encourage students to use the information from the Adventure Guide video as they work through the escape room, and remind them they can access the video on each page if they get stuck.
Relevant Vocabulary
- Producer – An organism that makes its own food using sunlight (e.g., plants).
- Consumer – An organism that eats other organisms for energy (e.g., animals).
- Decomposer – An organism that breaks down dead material and recycles nutrients (e.g., fungi, bacteria).
- Trophic Level – A level in the food web that represents the flow of energy.
- Photosynthesis – The process producers use to convert sunlight into energy.
Assessment
- Successful completion of the online escape room will serve as the primary assessment.
- Students must demonstrate understanding of producers, consumers, and decomposers by answering questions correctly and navigating the ecosystems.
Closing (Optional, if time permits)
- Conclude with a brief discussion, asking students what they learned about how energy flows through an ecosystem and why each part of the food web is important.
Teacher Reference Guide
The food web is an essential concept that helps students understand how different organisms in an ecosystem are connected. This lesson focuses on three main components of the food web: producers, consumers, and decomposers, and takes students on an exciting journey through three diverse ecosystems— the Amazon Rainforest, a Coral Reef, and the Arctic Tundra. In this guide, you’ll find the information needed to teach the key concepts and prepare students for the escape room activity.
Producers are organisms that make their own food through a process called photosynthesis, where they use sunlight to convert carbon dioxide and water into energy. In the Amazon Rainforest, the trees, plants, and other vegetation are examples of producers. These plants form the foundation of the food web because they create the energy that all other organisms in the ecosystem depend on. Students should understand that producers are the starting point of every food web.
Consumers are organisms that eat other organisms to obtain energy. Consumers can be classified as herbivores (plant-eaters), carnivores (meat-eaters), and omnivores (those that eat both plants and animals). In the Coral Reef ecosystem, fish, sharks, and other marine creatures serve as consumers. Students need to understand the concept of primary, secondary, and tertiary consumers. Primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers are often top predators. It's essential to convey that consumers rely on the energy initially created by producers to survive.
Decomposers are organisms that break down dead material, returning valuable nutrients to the ecosystem. This process is vital for recycling energy within the food web. In the Arctic Tundra, decomposers like fungi and bacteria break down dead plants and animals, keeping the ecosystem balanced. Decomposers play a crucial role because they ensure that waste and dead matter are broken down into simpler substances that plants (producers) can reuse. Students should grasp that without decomposers, ecosystems would become overrun with dead matter, and nutrients would not be recycled.
Once the concepts of producers, consumers, and decomposers have been covered, guide students to watch the Adventure Guide video, which will reinforce the information you've taught. Remind them that this video will be available to reference throughout the online escape room activity. The escape room is designed to engage students and assess their understanding of food webs as they navigate challenges related to the three ecosystems. Students will answer multiple-choice questions, solve riddles, and complete puzzles to move through each environment and successfully complete the escape room.
During the lesson, emphasize the interconnectedness of the food web, how energy flows from one organism to another, and why each part of the web is essential for ecosystem balance. Encourage students to think about how the removal or addition of one species can affect the entire food web. Understanding this relationship is key to comprehending the importance of biodiversity and balance within ecosystems.
This reference guide is structured to help you lead students through the information necessary to complete the escape room while reinforcing the core science concepts of food webs. The goal is for students to recognize that ecosystems are complex networks of relationships, all driven by the flow of energy through producers, consumers, and decomposers.
