8 Hands-On Food Chains and Food Web Activities for Upper Elementary (Grades 3-5)

Looking for hands-on food chains and food web activities for your upper elementary science classroom? These 8 activities help students in grades 3–5 understand producers, consumers, decomposers, energy flow, predators, prey, herbivores, carnivores, and omnivores — all through projects they can actually touch, build, and move around in.

Because let’s be honest — reading about food chains from a textbook doesn’t stick. But standing in a circle passing yarn between organisms while watching the web form in front of them? That sticks. Here are eight ways to make it happen.

Science Standards these Food Chain Activities Cover

NGSS (Next Generation Science Standards):

• 5-LS2-1 — Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. (Activities #1, #3, #4, #5)
• 3-LS4-3 — Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all. (Activities #2, #3, #6)
• 3-LS4-4 — Make a claim about the merit of a solution to a problem caused when the environment changes. (Activities #3, #7)
• 5-LS2-2 — Use a model to describe how any group of organisms and the nonliving environment interact as a system. (Activities #1, #3, #5, #8)
• 3-LS2-1 — Construct an argument that some animals form groups that help members survive. (Activity #6)

Texas TEKS (updated 2024–25):

• TEKS 3.12A — Explore and describe how organisms in an ecosystem interact, including producers, consumers, and decomposers within food chains. (All activities)
• TEKS 4.12A — Investigate how organisms in an ecosystem interact in food webs, identifying producers, consumers, and decomposers. (Activities #1, #3, #5, #8)

• TEKS 5.12B — Predict how changes in the ecosystem affect the cycling of matter and flow of energy in a food web. (Activities #3, #7)

These food chain activities work perfectly as part of a larger ecosystem unit. If you’re looking for a complete set of ecosystem project ideas, check out my 10 ecosystem activities and project ideas for upper elementary.

Key Food Chain Vocabulary Your Students Need To Know

Before diving into the activities, make sure your students understand these terms. You can introduce them with a quick anchor chart, a foldable, or a vocabulary sort before starting the hands-on work:

• Producer — An organism that makes its own food, usually through photosynthesis. Examples: grass, trees, algae, phytoplankton.
• Consumer — An organism that eats other organisms for energy.
• Primary Consumer — Eats producers directly. Also called herbivores. Examples: rabbits, deer, caterpillars.
• Secondary Consumer — Eats primary consumers. Examples: frogs, small birds, foxes.
• Tertiary Consumer — Eats secondary consumers. Often top predators. Examples: hawks, wolves, sharks.
• Decomposer — Breaks down dead organisms and returns nutrients to the soil. Examples: mushrooms, earthworms, bacteria.
• Food Chain — A single path showing how energy moves from one organism to another.
• Food Web — Multiple overlapping food chains in an ecosystem, showing how organisms are interconnected.
• Predator — An animal that hunts and eats other animals.
• Prey — An animal that is hunted and eaten by other animals.
• Herbivore — Eats only plants.
• Carnivore — Eats only animals.
• Omnivore — Eats both plants and animals.
• Energy Flow — The transfer of energy from the sun to producers to consumers to decomposers.

Activity 1 – Food Chains Hanging Mobile Craft

To start off, let’s explore a classic favorite: creating a hanging mobile. Start by assigning each student a biome (or letting them choose one from a list) to ensure your classroom has a healthy level of diversity. If you’d like, you can also allow students to work in pairs. Hooray for cooperative learning!

Each student (or pair of students) must then identify a producer, a primary consumer, a secondary consumer, a tertiary consumer, and a decomposer that fit within their assigned biome. Then, they should draw and color their biome-appropriate organisms to the best of their ability. The more color, the better, right?

Since these images will be the hanging pieces of the mobile, I recommend folding a sheet of paper into quarters and keeping each organism’s picture within one quarter of the paper to ensure consistently sized mobiles. Once their drawings are finished, students should then flip the paper over. On the back, they should record their organism’s role in the food chain; whether it is an herbivore, carnivore, or omnivore; and which biome they belong to.

Next, students can cut out their organisms, being careful not to cut through their writing on the back. I recommend simply cutting along the folds of the paper rather than cutting along the outline of the drawings. Afterward, it’s assembly time! Use a hole puncher and yarn to carefully connect the organisms, making sure the mobile follows the order of the food chain.

From there, simply attach the top of the homemade food chain to a hanger or hook, and voila! One hanging mobile is ready for display wherever you’d like. If you have a drop ceiling, you can even hang the mobiles from there!

Materials Needed:

• paper (folded into quarters)
• colored pencils or markers
• scissors
• hole punch
• yarn or string
• hangers or ceiling hooks
• tape

Activity 1 Time Estimate: 45–60 minutes (can be split across two class periods)

Love the mobile idea? I also have a full Ecosystems Hanging Mobile resource that covers all major biomes, with three differentiation options.

Activity 2 – Food Chains Causation Cards (Food Chain Vocabulary Review)

That’s right: more engagement coming your way! Whether you’re looking to introduce the concept of food chains and food webs or you want to reinforce prior learning, causation cards are an excellent choice.

If you’re new to the causation card scene, allow me to give you a brief overview. Every card in the set has an action to perform and an informative phrase to say aloud, along with instructions on when to speak to ensure students pay attention to other performers. These actions are color-coded for accessibility, too. Sometimes an action will have an associated prop, but they’re always common classroom items!

The phrases and actions on the causation cards are often definitions of terms or explanations of processes. With integration of both speaking and listening skills, it’s an excellent opportunity to build fluency, prosody, and reading accuracy while still exploring your science topic. After all, we love an integrated curriculum!

You can find my food chains and food webs causation cards here!

Besides building those necessary skills, causation cards are a great way to interact with food chains. Allowing students the opportunity to move and speak is a surefire way to captivate their attention and ensure engagement. Those tricky vocabulary terms just became a lot more memorable!

Materials Needed:

• causation card set (see link below for my printable set)
• optional props (common classroom items as described on cards)

Activity 2 Time Estimate: 15–20 minutes (great warm-up or review activity)

Activity 3 – Food Chains and Food Web Activities Collage

Full disclosure: this one will require materials that you may have to collect from outside the classroom. To save on these materials, you’ll want to divide students into groups. Provide these groups with magazines, newspapers, and other materials to create collages of food chains! Of course, these materials should be ones that you’re okay with losing, since students will need to cut out images of organisms.

As they find organisms, the group should work together to arrange them into a food chain on a piece of construction paper. Some organisms, like beetles or fungi, may be hard to find if you aren’t using nature magazines or the like. If students absolutely cannot find a creature to fit a role in their food chains, consider allowing them to use technology to print an image or simply draw the organism directly on paper.

Once the food chain is finished, students should decide which biome best fits their menagerie of organisms. They can also add more organisms they encounter to shift their food chains into food webs.

These collages can be displayed, too — they’d make a great hallway display!

Materials Needed:

• old magazines (National Geographic Kids, Ranger Rick, or printed images)
• scissors
• glue sticks
• large construction paper or poster board
• markers for labeling

Activity 3 Time Estimate: 40–50 minutes (allow extra time for magazine searching)

Activity 4 – Yarn Food Web (Whole Class Activity)

In this whole-class activity, start off by assigning each student an organism or letting them choose from a pre-made list. It’s a good idea to use creatures from the same biome to ensure all organisms are related, or else you’ll end up with one wacky food web!

Once they have their organism, students should write it down in large letters on a horizontal sheet of paper and either tape it to their shirt or hold onto it to set on the floor in front of their feet. This is so that other students can see, at a glance, which organism everyone is.

Then, students will form a big circle around the room. The activity will kick off by giving a ball of yarn to one student. This student will then pass it to someone else in the circle who has an organism connected to their own in the food chain. The important part is this: when passing the ball of yarn, the original student should keep some of the string for themselves so everyone can see where the connections have led.

In addition, the student passing the yarn ball should also explain how their organisms are connected using vocabulary terms. For example, the interaction could look like this: “As an earthworm, I am a decomposer who returns nutrients to the soil for you, the grass, to get energy as a producer.”

The yarn passing should continue in this way until there are no more available connections that make sense. When this happens, toss a new ball of yarn in a different color to continue. By using different colors, students can more easily visualize the different food chains that make up a food web.

It’s important to note that the yarn ball can be passed either up or down the food chain so long as there is a direct connection. A producer cannot pass the energy in the form of organic matter to another producer, but they may pass it to either a primary consumer or a decomposer.

Also, to ensure everyone can participate, try to assign an equal number of each organism type. For instance, if you have 25 students, aim for 5 producers, 5 of each consumer type, and 5 decomposers.

Materials Needed:

• Ball of yarn
• organism name cards or half-sheets of paper
• tape (for attaching name cards to shirts)
• scissors
• markers
• Optional: printed organism images instead of handwritten names.

Activity 4 Time Estimate: 20–30 minutes (whole-class, high engagement)

The yarn food web is one of the most memorable ecosystem activities you can do. For more ways to make ecosystem lessons collaborative, check out my post on collaborating with this easy ecosystems activity.

Activity 5 – Food Chains Fishing (Partner Activity)

Fishing for food chains is another partner activity! For this one, you’ll want to do some prep ahead of time. Create a set of construction-paper organisms (I recommend 15 or 20 cards, with an equal number of each type of organism found in food chains) and attach paper clips to each “card.” You can either make the “fishing rods” yourself or have students do it; regardless, the fishing rods are made by tying a string to a dowel or stick and attaching a magnet to the end of the string.

Have students partner up, and give each pair a set of cards and a fishing rod. To get started, kiddos should spread the cards out face down and take turns “fishing” for organisms with the magnet. When they “hook” a card, the student should turn the card over to reveal which organism they fished up. Then, they determine where the organism fits within food chains, such as a producer, decomposer, or one of the three consumer levels.

In addition, the student should provide an example of another organism connected to it, either above or below it on the food chain, and explain how they are related. If the other student agrees with all of their answers, then they get to keep the card. Continue in this manner until all the cards are finished. Whoever has the most cards at the end wins!

Materials Needed:

• construction paper or 15-20 index cards
• paper clips
• string
• dowel or stick-like material
• magnets
• hole puncher
• writing utensils

Activity 5 Time Estimate: 20–25 minutes (plus 15–20 minutes prep time to make the cards, rods, and magnets ahead of time)

Activity 6 – Food Chains Hands-on Activities Game

Similar to the fishing-for-food-chains activity, create a set of construction-paper organisms and provide each student with one set. Students will then find a partner to start the fun! Before beginning, everyone should shuffle their deck of cards and then stack them face down on the table.

As in a traditional game of War, both students will flip the top card of their deck at the same time. Then, they will compare the two organisms. Whoever has the organism that is higher on the food chain wins that round, and they get to take both cards.

It’s important to note that, in order for the game to work properly, you’ll want to decide ahead of time if you want decomposers to be the lowest or highest tier on the food chain. Personally, I recommend the following order: decomposers > tertiary consumers > secondary consumers > primary consumers > producers. Of course, it’s up to you!

Students should continue flipping cards and comparing them until no cards remain. Whoever has the most cards collected at the end of the game wins!

Materials Needed:

• construction paper or index cards
• writing utensils

Activity 6 Time Estimate: 15–20 minutes (fast-paced — great for end of class or review day)

Activity 7 – Food Chains Relay Race Team Game

This is another class-wide activity, though your class will be divided into two teams. Each team should form a line facing the whiteboard. Provide each time with a dry-erase marker to share.

For every round of this activity, you must come up with an organism for each team. The students at the front of the line for their teams should then hurry to the whiteboard and write an organism connected to their organism on the food chain, along with a brief explanation of how they’re connected.

For instance, if you choose “grass” for a team, that team’s student could write “grasshopper: primary consumer” or “earthworm: decomposer,” since both are either directly above or below grass on the food chain.

Once a student has answered with a correct response, they hurry back to their team and pass the marker. Then, the process repeats! Continue until one team has made it through all their students. The first team to do so is the winner!

Since this means the other team may have members who didn’t get to participate, you can go through several games to ensure everyone gets a turn.

Materials Needed:

• dry-erase markers
• whiteboard(s)

Activity 7 Time Estimate: 15–20 minutes per round (plan for 2–3 rounds so everyone participates)

Activity 8 – Food Chains Memory Match Cards

Once again, it’s time to break out the organism cards! Create a set of construction paper cards, each featuring an organism. The caveat is that there should be an even number of cards in the set, since this activity is a matching game. In addition, there should be an even number of each type of organism in food chains. For instance, you could have four producers, four decomposers, and four of each consumer type.

Have students partner up and provide each pair with a deck of cards. Then, they should spread the cards face down and take turns flipping over two cards at a time. If the two flipped cards are the same type of organism, like an earthworm and a fungus, then it’s a match! The student then gets to keep both cards.

If the cards are not the same type of organism, however, the cards should be flipped back over, and the student’s turn is over.

For clarity, it may help to label each card with the organism’s role within food chains, as some animals can fluctuate between secondary and tertiary consumers depending on the ecosystem. There’s no need to make it tricky!

The students should take turns flipping cards until all the cards are collected. Whoever has the most cards at the end wins the game! This activity can be quick, so it’s definitely possible to squeeze in a few rounds.

Materials Needed:

• construction paper or index cards
• writing utensils
• images of organisms (can print out or draw)

Activity 8 Time Estimate: 10–15 minutes per round (quick enough to squeeze in multiple rounds)

Ready to assess understanding? My Food Chains Task Cards cover food chains, food webs, producers, consumers, decomposers, predators, prey, herbivores, carnivores, and omnivores — and they work as science centers, review stations, or a quick formative assessment.

How to Use These Activities in Your Unit

You don’t need to do all eight. Here’s a suggested sequence depending on how many days you have:

If you have 1 day: Do the Yarn Food Web (#4). It’s whole-class, takes one period, and gives students the strongest visual understanding of how food webs work.

If you have 2–3 days: Start with the Causation Cards (#2) to introduce vocabulary, then do the Yarn Food Web (#3) to build understanding, then finish with the Hanging Mobile (#1) or Collage (#4) as a culminating project.

If you have a full week, use all eight activities as stations. Set up 4 stations per day, rotate groups through them, and finish the week with a food chain assessment using task cards.

If you’re integrating with your ecosystem unit, start with my ecosystem overview activity, move into these food chain activities, and finish with the full ecosystem project ideas as a culminating assessment.

In Conclusion

By incorporating these eight hands-on activities into your food chains lesson plans, you’ll significantly boost your kiddos’ engagement and deepen their understanding of food chains and food webs. In addition, when there’s active participation, like speaking and collaborating, students are much more likely to retain what they learn, and maybe, just maybe, you’ll spark a further interest in science!

If you’re ready to check for understanding, check out my food chains task cards! They’re a perfect way to review content and provide you with a covert assessment. You could even use them as science centers if you’re feeling adventurous!

You know your classroom best, so I have every confidence that you’ll choose activities that are a good fit for your upper elementary science students. Although, to be fair, it’s always a win as long as there are real-world connections and teamwork involved! No matter which activity you choose from this list, you can be assured you’re building a comprehensive understanding of food chains.
