Overview

In this lesson mini, students discover how energy flows from the Sun through living things. Students first explore key energy flow vocabulary through movement and visual displays. They then investigate how the Sun’s energy moves through food to power their daily activities. Finally, students use games and models to demonstrate energy transfer between producers and consumers in nature. Through hands-on activities and investigations, students build understanding of how all living things depend on the Sun’s energy to survive.

Key Vocabulary & Definitions

consumer (noun): a living thing that gets its energy by eating other living things

energy (noun): the power to make things happen or cause changes

energy flow (noun): the movement of energy from one living thing to another

food chain (noun): a model that shows how energy passes from one living thing to another in a line

produce (noun): a living thing (usually a plant) that makes its own food using energy from sunlight

sunlight (noun): light and energy that come from the Sun

Authentic Learning Extensions

Authentic learning opportunities for studying energy from the Sun and food chains involve real-world experiences and practical applications that help students understand energy concepts meaningfully. Here are some examples:

Food Energy Connections: Help students trace energy flow through the foods they encounter daily. Examine school lunches, grocery store items, or foods from home gardens. Have students identify which foods come directly from producers (such as vegetables, fruits, and grains) and which come from consumers (such as dairy products and eggs). Create simple diagrams showing how the Sun’s energy travels through food chains to reach their plates. Discuss how different cultures use various producers and consumers in their traditional foods.

Nature Investigations: Guide students in exploring food chains through local environments including the schoolyard, nearby parks, or school gardens. Give students observation journals to record plants and animals they discover during a 20-minute exploration. Have them sketch producers such as trees or grass and look for evidence of consumers such as nibbled leaves, spider webs, or bird nests. Ask students to use their science vocabulary to explain how energy flows through the living things they observe. Create a class display of local food chains using student sketches and photographs.

Prepare for Activity: Write the following vocabulary words and definitions on the board (see step 8):

consumer (noun): a living thing that gets its energy by eating other living things

energy (noun): the power to make things happen or cause changes

food chain (noun): a model that shows how energy passes from one living thing to another in a line

producer (noun): a living thing (usually a plant) that makes its own food using energy from sunlight

sunlight (noun): light and energy that come from the Sun

Begin the activity by displaying the Energy Flow starter diagram and drawing students’ attention to it. Introduce key vocabulary that students will explore: consumer, energy, food chain, producer, and sunlight.

Point to each part of the diagram while introducing the terms sunlight (energy from the Sun), producer (like the plant), and consumer (like the animal).

Demonstrate the meaning of energy by showing motion or movement with your hands, defining it as “the power to make things happen.”

Ask students to provide their own examples of energy transfer in nature.

Explain that this whole system showing how energy moves is called a food chain.

Tell students that during today’s activity they will see how energy from the Sun moves through living things in nature. Ask: “Where do you think all living things get their energy from?” Allow a few student responses to activate prior knowledge. Encourage students to make connections to their prior science knowledge about photosynthesis and cellular respiration.

As a class, read the Food Chain article, focusing on how living things depend on each other for food and identifying the producers and consumers in both the land example (plant → rabbit → hawk) and the ocean example (diatoms [single-cell life] → shrimplike creatures → small fish → bigger fish).

Begin a movement activity by having students stand in a circle. Tell students they will model energy transfer through an ecosystem. Explain that they will demonstrate how energy flows through living things.

Select one student to be the Sun. Give the student a yellow hat or ribbon to wear and a yellow ball or beanbag to represent energy from the Sun. Ask the class to repeat together: “The [ball or beanbag] represents sunlight, which is energy from the Sun.”

Ask students to name some producers (e.g., plants, trees, grass). Choose a student to be a producer and have the student stand next to the Sun. Consider giving the producer student an index card with a clear label that reads “producer.” Have the class chant: “Producers make their own food using sunlight.”

Have students identify local animals that eat plants. Select a student to be a consumer, and position the consumer next to the producer. Consider giving the consumer student an index card with a clear label that reads “consumer.” Have the class recite: “Consumers get energy by eating other living things.”

Remind students they’re creating a food chain to show how energy moves.

Have students demonstrate energy transfer using these steps (the class can make a whoosh sound during each energy transfer):

When the Sun passes the ball or beanbag to the producer, the student portraying the Sun will say, “I am the Sun. My light gives energy to the producer.” The class will recite: “The sunlight gives energy to the producer.”

When the producer passes the ball or beanbag to the consumer, the student portraying the producer will say, “I am the producer. I give energy to the consumer.” The class will recite: “The producer gives energy to the consumer.”

Repeat this process two or three more times with different students. Do the following in each round:

Have the students who are observing narrate using key vocabulary from the activity: “First the sunlight gives energy to…,” “Then the producer uses the energy to…,” “Finally the consumer gets energy by…”

After each demonstration, have students draw the energy chain they just observed in their science notebooks.

Ask: “How was this similar to other chains or cycles we’ve learned about?”

Tell students that now that they have practiced acting out how energy moves through living things, they will create visual displays to help remember these important vocabulary words.

Review the vocabulary words displayed on the board:

Read each word aloud and have students repeat it.

Share the definition and ask students to make connections to the movement activity they just completed.

For each word ask, “How did we show this word in our energy chain activity?”

Point out that these are all words that help explain how energy moves through living things.

Divide the class into small groups of three or four students and tell them they are going to create a word sketch. Refer to the Word Sketch instructional strategy for additional procedural support. Then assign each group one vocabulary word:

consumer (noun): a living thing that gets its energy by eating other living things

energy (noun): the power to make things happen or cause changes

food chain (noun): a model that shows how energy passes from one living thing to another in a line

producer (noun): a living thing (usually a plant) that makes its own food using energy from sunlight

sunlight (noun): light and energy that come from the Sun

Give each group a large sheet of white paper and coloring supplies. Have them write their word creatively in the center of the paper (for example, sunlight could be written in yellow with rays coming out of it).

Ask the groups to create a visual display around their assigned words. Offer suggestions such as the following:

Draw pictures showing examples (such as a plant for the word producer).

Write a simple definition in your own words.

Draw arrows to show connections (such as Sun → plant for the word producer).

Add real-world examples you know.

Circulate while groups work, helping them make accurate connections and encouraging them to use what they learned in the movement activity.

To wrap up the activity, have each group briefly present its vocabulary display to the class, explaining its drawings and connections. Hang the completed vocabulary displays on the wall where students can reference them during future activities.

Differentiation and Variations

Definition Support: Provide each group with a simple definition card that includes its vocabulary word, a kid-friendly definition, and a simple example drawing. For instance, a producer card would read, “A producer is a living thing that makes its own food using sunlight,” and would show a simple drawing of a plant in sunlight. Starting with a clear definition helps students build from a solid foundation of understanding before they begin creating their own visual representations.

Group Discussion: Support deeper understanding by giving each group one simple discussion question to think about as they create their posters. Ask questions that connect to students’ experiences, such as “How would you explain this word to a younger student?” or “Where do you see examples of this word in nature near our school?” Have students use words and pictures to include their answers to these questions on their posters. Inviting students to connect vocabulary to their own experiences and explain concepts in their own words helps make abstract science concepts more concrete and memorable.

Picture Sort Activity: Provide groups with a set of simple pictures (e.g., plants, animals, Sun) and have them sort the pictures based on whether they relate to their assigned vocabulary words. Students can glue these pictures onto their posters and explain why they chose each picture.

Collaborative Teaching

One Teaching, One Assisting: For collaborative teaching and learning environments, this learning activity is well-suited to a One Teaching, One Assisting strategy. In this model, one teacher leads the activity while the other circulates, assisting individual students as needed. This ensures that when students encounter difficulties, they receive immediate help in the form of personalized support and answers to their questions. By addressing students’ unique needs and keeping them on track, this approach enhances individual learning experiences and fosters a supportive classroom environment. Studies indicate that immediate feedback and individualized attention can significantly enhance student understanding and retention of material.

Activity Introduction: One teacher leads the opening explanation about learning how energy moves through living things while the other distributes materials and helps arrange students in the circle formation.

Movement Activity: One teacher leads the energy transfer demonstration while the other helps position students, manages materials, and ensures all students are engaged in the circle activity.

Visual Vocabulary Work: While one teacher explains the vocabulary poster task and monitors timing, the other circulates among groups to clarify vocabulary definitions, suggest examples, and ensure scientific accuracy in student work.

Group Presentations: One teacher facilitates the group presentations while the other assists with displaying student work, manages transitions between groups, and helps guide student explanations of their vocabulary displays.

Activity Wrap-Up: One teacher leads the final discussion connecting the movement activity to the vocabulary displays while the other helps post student work and ensures all students can articulate how energy flows from the Sun to producers to consumers.

Implementation

Prepare for Activity: Cut out enough sets of Food Image Cards so that each group of four or five students has its own set. Also cut out a set to use as a model.

Begin the activity by asking students, “Where does the energy you need to run and play come from?” Scribe students’ responses on the board.

Tell students that today they’ll discover how energy from the Sun helps them grow and move. Present two scenarios: “Imagine you’re going to play in the park and want to run fast. What does your body need for energy?” and “When you’re very hungry, what can you eat to get energy again?” After gathering responses, explain how food provides the energy for all our activities. Consider sharing that everything we do—from running and jumping to growing and thinking—requires energy and that energy comes from the food we eat. Encourage students to think of food as their body’s fuel, just as a car needs gas to run.

Organize students into groups of four or five. Give each group a large sheet of poster paper, coloring supplies, and a pack of sticky notes. Explain that they’ll use these materials to create energy path diagrams.

Guide groups to draw a large sun circle on their paper. Model each action along with them using the whiteboard or display. Have them draw arrows connecting the Sun to circles to represent plants and then more arrows connecting the Sun to circles representing animals, including humans. Encourage students to draw the human a bit larger so that they have room to label it. Students will use sticky notes to label body parts and activities that require energy.

Give each group a set of Food Image Cards. Direct students to do the following:

Look at their food cards. Sort them into two piles, one for foods that come directly from plants and one for foods that come from animals.

Place their plant food cards on their drawings with arrows going from the Sun to these foods.

Show how animals get their energy by eating plants by placing their animal food cards on their drawings with arrows going from the plants to the animal foods.

Draw arrows from both piles to their drawings of a human to show how we get energy from both plants and animals. Consider modeling this for students by sharing the following example:

Let’s look at how energy moves to us through rice. The Sun gives energy to the rice plant as it grows. When we eat rice, we get that energy directly from the plant. But when we eat eggs, we’re getting energy that moved from the Sun to the wheat that the chicken ate, to the chicken that laid the egg, and finally to us. This shows how the Sun’s energy moves through different living things before reaching us.

Have groups discuss which foods provide more or less energy.

Facilitate group presentations in which students explain their energy chains and reasoning. Guide discussion with questions such as “How does the Sun’s energy reach us through food?” and “Why do we need different types of food for energy?”

To wrap up, gather in a circle for a final reflection. Have students share what they found most interesting about the connections between the Sun and food energy and how this knowledge applies to their daily lives.

Differentiation and Variations

3-Circle Venn Diagram: Provide students with a 3-Circle Venn Diagram graphic organizer with the circles labeled with the words Sun, food, and body along with word banks for energy-using activities (e.g., running, growing, thinking) and body parts that need energy. Students can focus on making connections rather than creating the entire diagram. This supports students’ learning by reducing their cognitive load and allowing them to demonstrate understanding without being hindered by drawing or recalling vocabulary.

Branching Energy Pathways: For students who would benefit from a challenge, ask them to create branching energy pathways showing multiple steps of energy transfer (Sun → grass → cow → milk → human) and calculate how many transfers occur before energy reaches humans in different food examples. These students can also research and add specific nutrients (e.g., carbohydrates, proteins) to their diagrams, explaining which body functions use each type. This deepens students’ learning by encouraging them to analyze more complex energy relationships and connect to broader scientific concepts about nutrition and body systems.

Physical Energy Story: Invite students to become “energy journalists.” Have each group create a news report about its food’s energy journey, with students taking turns being news anchors; field reporters interviewing the Sun, plants, and animals; and camera operators using a cardboard “camera frame.” Groups perform their news stories for the class, explaining how energy moves from the Sun through their assigned food items to humans, bringing the energy transfer concept to life through dramatic play and storytelling. This supports students’ learning by allowing them to verbalize the concept of energy transfer in their own words while engaging multiple learning styles through movement, speaking, and creative expression.

Collaborative Teaching

One Teaching, One Assisting: For collaborative teaching and learning environments, this learning activity is well suited to a One Teaching, One Assisting strategy. In this model, one teacher leads the activity while the other circulates, assisting individual students as needed. This ensures that when students encounter difficulties, they receive immediate help in the form of personalized support and answers to their questions. By addressing students’ unique needs and keeping them on track, this approach enhances individual learning experiences and fosters a supportive classroom environment. Studies indicate that immediate feedback and individualized attention can significantly enhance student understanding and retention of material.

Activity Introduction: The lead teacher facilitates the whole-class discussion about energy sources and maintains the list of student ideas scribed on the board. The assisting teacher circulates to encourage participation from quieter students and helps capture additional ideas that students may be hesitant to share aloud.

Activity Setup and Instructions: The lead teacher explains the drawing activity directions and demonstrates how to create the energy pathway diagram with arrows. The assisting teacher distributes materials to groups and ensures each group has proper supplies and a workspace set up for success.

Drawing Activity: The lead teacher monitors overall progress and provides whole-group guidance about key elements to include in the diagrams. The assisting teacher moves between groups to help with drawing organization, proper arrow placement, and labeling of energy-using activities.

Food Card Activity: The lead teacher introduces the food-sorting concept and facilitates the sharing of examples about energy in different foods. The assisting teacher helps groups sort their cards correctly, prompts deeper thinking about energy pathways, and ensures all students participate in discussions.

Group Presentations: The lead teacher facilitates group sharing time and guides the discussion about energy transfer patterns. The assisting teacher supports groups waiting to present by helping them to prepare their explanations and notes common misconceptions to address.

Activity Wrap-Up:The lead teacher guides the final discussion, connecting the activity to real-world energy use and food choices. The assisting teacher helps students articulate their learning using scientific terms correctly.

Implementation

Begin the lesson with a basic review of energy to activate thinking by asking students questions such as the following:

What is energy?

Where does energy come from?

Present two problem situations to the class, using the Think-Pair-Share instructional strategy to facilitate the review and discussion of the following questions:

Why do birds migrate to warmer places during winter?

Why do some animals hibernate in winter while others do not?

Summarize how animals use energy every day in ways similar to how students use energy every day. Use specific examples such as local wildlife in parks or animals specific to your area. Consider saying the following and personalizing it to your location:

Let’s think about the animals you might see around where you live. Wherever you are in the world, there are animals living near humans—maybe you see them outside your home, in your community, or in nearby natural areas. These animals all need energy to live, just like you do! Think about the small animals you see searching for food—they might be birds looking for seeds, insects buzzing around plants, or other creatures finding what they need to eat. They’re gathering that food because they need energy to survive, just like how you need to eat to have energy to play and do your schoolwork. In fact, right now, there are probably animals near us using energy to fly, crawl, run, or swim. They’re trying to find food, build homes, and take care of themselves, similar to how we use energy for our daily activities. Whether we live in a big city, a small town, or the countryside, we share our world with animals that are looking for and using energy, just like we do!

Introduce the lesson’s main topic by telling students that today they’ll learn how animals use environmental energy to live and grow. Emphasize the three main energy sources: the Sun, plants, and other animals.

Divide the class into small groups and assign an animal to each group or let groups choose an animal to research. Tell students that working as a group, and using a device for the group, they will research their assigned or chosen animals and identify the animals’ primary energy sources. They will use Britannica School or another approved database to help them research.

Give each group a copy of the Animal Energy Sources handout. Tell students that they will record their answers to the questions on the handout so that they can use the information to create an animal illustration to share with the class. Preview the questions as a class:

What does your animal eat to get energy?

How does it find or catch its food?

Where does it find its food?

What does it use energy for every day?

Does it need more energy during certain times of the year?

Give each group a large sheet of poster paper and coloring supplies. Invite the groups to use the information they recorded on their Animal Energy Sources handouts to create an illustration showing the animal with its energy source. Display the Giraffe Illustration Example for students. Model a description of this illustration using information gathered about the giraffe. As you share the following information, point to where this is shown in the displayed illustration.

What does your animal eat to get energy? I learned that the giraffe gets its energy from eating leaves, especially from acacia trees. The giraffe is an herbivore, which means it eats only plants.

How does it find or catch its food? The giraffe finds its food by using its very long neck—up to 6 feet long!—to reach high into tall trees where other animals can’t reach. It wraps its long tongue around branches to pull leaves into its mouth.

Where does it find its food? The giraffe finds its food in the African savanna, where there are lots of scattered trees, especially acacia trees, which are the giraffe’s favorite.

What does it use energy for every day? Every day, the giraffe uses energy to walk long distances between trees—sometimes up to 20 miles! It also needs energy to keep its huge body moving, reach high into trees, and stay alert for predators.

Does it need more energy during certain times of the year? The giraffe needs more energy during the dry season when leaves are harder to find. The giraffe might have to travel farther to find enough food.

Arrange students in a circle for the group discussion. Facilitate short group presentations, allowing each group to share its findings. Lead the discussion by asking probing questions about energy sources and transfer methods, such as the following:

Let’s compare animals! How is the way your animal gets its food different from what we learned about [another group’s animal]?

Think about the Sun—even if your animal doesn’t get energy directly from the Sun, how does the Sun help your animal get energy?

What would happen to your animal if it couldn’t find its favorite food anymore? What might it do?

To wrap up the activity, have students share their most significant learnings from the lesson.

Differentiation and Variations

Modified Research Guide: Provide a modified research guide that includes simplified questions with sentence frames. For example, instead of asking “What does your animal eat to get energy?” the modified guide would include “My animal eats _____________ for energy” and “It finds food by _____________.” This structured approach reduces students’ cognitive load and gives them clear pathways to express their understanding.

Preselected Animals: Create a list of animals with readily available information and clear energy connections, such as rabbits, squirrels, and common local birds. This helps students by allowing them to focus on familiar animals, making the content more accessible and relatable to their daily experiences. Additionally, providing visual research aids with pictures showing the animals’ food sources and behaviors supports visual learners and English language learners by offering multiple ways to access and understand the information.

Challenge Questions: Add challenge questions about energy relationships in ecosystems. Students can explore how their animals compete with other species for energy sources and analyze what would happen to the ecosystem if their animals’ energy sources disappeared. These questions promote systems thinking and deeper ecological understanding.

Energy Research: Encourage research into energy-efficiency adaptations by having students investigate how their animals conserve energy and what special features help them use energy effectively. This enrichment connects to evolutionary biology and advanced science concepts. Furthermore, incorporating quantitative energy analysis allows students to explore how many calories their animals need daily and to compare energy needs across seasons, supporting mathematical thinking and data-analysis skills.

Energy Web Investigation: Invite small groups to explore energy relationships by researching multiple species within a local ecosystem (such as a forest, pond, or park) and create a visual energy web showing how energy flows between organisms. Students then apply their understanding by designing an “energy smart” habitat that would efficiently support their chosen organisms and then share their learning through an interactive museum-walk format. This expanded version of the original activity deepens understanding of ecological relationships while incorporating engineering design and real-world applications, making it especially effective for older students or as an extension activity.

Collaborative Teaching

Activity Introduction and Review: The lead teacher facilitates the Think-Pair-Share discussion about energy concepts and bird migration while the assisting teacher circulates through the classroom to ensure that all students are participating in their pairs and to gather initial insights about student understanding.

Animal Energy Sources: The lead teacher presents the main concepts about energy sources (the Sun, plants, and other animals) and explains the group research task. Meanwhile, the assisting teacher distributes the Animal Energy Sources handouts and supports the formation of groups, ensuring that all students are included and understand the assignment.

Group Research: The lead teacher maintains overall classroom management and provides general guidance about using the Britannica School database and answering the research questions. The assisting teacher moves among groups to troubleshoot technology issues, help students navigate the research resources, and provide additional support to groups that may be struggling to find relevant information about their animals.

Group Illustrations: The lead teacher displays and explains the Giraffe Illustration Example, modeling how to incorporate research findings into the illustration. The assisting teacher circulates to support students as needed, providing support to students who need help connecting their research to their drawings.

Presentation and Discussion: The lead teacher facilitates the group sharing and guides the discussion with probing questions about energy sources and transfer methods. The assisting teacher helps manage the transition into the circle formation, supports groups in preparing their presentations, and ensures student work is displayed properly during sharing time.

Activity Wrap-Up: The lead teacher facilitates the conversation while the assisting teacher notes key takeaways and helps to ensure all students have an opportunity to share their insights about animal energy sources.

Implementation

Prepare for the Activity: Cut out enough sets of cards for the Energy Flow Game so that each group of four or five students has its own set. Also cut out a set to use as a model.

To activate prior knowledge, ask students, “What do you think gives animals the energy to run and play?” Scribe students’ responses on the board.

Tell students that during today’s activity they will show how energy moves from the Sun to animals, and explain how animals use this energy to live. Present two key questions to spark curiosity:

Do you know how plants grow and where they get energy from?

What about animals, how do they get the energy they need to move and live?

After gathering responses, explain to students that just like we need food for energy to move and grow, all living things need energy to survive, and today they’ll discover where this energy comes from.

After students share responses, emphasize why understanding energy flow is essential for life on Earth and share that the Sun acts like a giant battery providing energy to everything around us. Explain that all animals, including humans, are indirectly powered by the Sun through plants.

Divide the class into groups of four or five students for the Energy Flow Game. Give each group a set of cards representing the Sun, plants, herbivorous animals, and carnivorous animals. Each card includes a description of how the pictured component obtains energy.

Instruct students to arrange their cards in sequence to show the energy flow from the Sun to the carnivores. Walk around the room to guide groups and answer questions as they work.

After groups complete their sequences, lead a class discussion in which groups explain the reasoning behind their arrangement of the cards. Use this time to connect students’ insights to lesson concepts and address any misconceptions.

Give each group a large sheet of poster paper and coloring supplies. Invite the groups to create drawings that show energy flow in nature. Tell them they must include the Sun, plants, animals, and arrows to show energy movement between components.

Gather all students in a large circle to share their work. Have each group display and explain their drawing, emphasizing specifically how the arrows represent energy movement between each component.

After all groups have shared, summarize the discussion to highlight energy flow patterns and the Sun’s crucial role.

To wrap up the activity, ask students to pause and think about the following questions (consider writing them on a whiteboard or display):

What did I learn today about energy flow in nature?

Why is the Sun important for the life of plants and animals?

After giving students appropriate thinking time, invite volunteers to share their thoughts with the class, summarizing key points about energy flow and the Sun’s importance.

Differentiation and Variations

Predrawn Arrows: To support learners, predraw arrows on the poster paper with labels such as “gives energy to” or “flows to.” This allows students who might struggle with the abstract concept of energy transfer to focus on placing their components in the correct locations rather than determining both placement and energy flow direction simultaneously.

Energy Example Elaboration: To increase rigor, encourage students to add specific examples of energy use at each level of their diagram, such as how a plant uses energy to grow new leaves, how a rabbit uses energy to hop and stay warm, and how a fox uses energy to chase prey and care for its young. This encourages students to think concretely about energy transformation while connecting to observable behaviors they can understand.

Energy Flow Diagrams: Have students create two different energy flow diagrams: one for a terrestrial ecosystem and one for an aquatic ecosystem. This allows them to compare and contrast how energy flows differently in these environments while reinforcing the universal nature of energy transfer principles. Students could focus in particular on how terrestrial plants function compared to aquatic plants in their respective food chains.

Collaborative Teaching

Activity Introduction and Review: During the opening review, the lead teacher facilitates class discussion while the assisting teacher monitors student engagement and encourages participation from hesitant students.

Activity Setup and Game Activity: As the lead teacher explains the Energy Flow Game rules and distributes materials, the assisting teacher helps organize groups and ensures all students understand the instructions. While groups arrange their energy flow cards, the lead teacher guides whole-class progress while the assisting teacher circulates to provide immediate support, clarify misconceptions, and offer scaffolding where needed.

Creative Activity: During the creative visualization activity, the lead teacher provides drawing prompts and monitors time while the assisting teacher helps individual groups incorporate proper vocabulary and accurately represent energy flow concepts.

Discussion: As groups share their conclusions in the final circle discussion, the lead teacher facilitates the conversation while the assisting teacher helps students articulate their ideas using scientific vocabulary and make connections between group presentations.

Activity Wrap-Up: The lead teacher summarizes key concepts while the assisting teacher displays student work and ensures all students have noted suggested extension materials.
