Birds Lesson Plan for Elementary Ages

  • Author:
  • Updated date:

I am a Christian. I was an 8th-grade American History teacher. I am currently a freelance writer, public speaker, & homeschooling mom of 9.


This is part 4 of a 5 part hands-on unit on zoology. Create an egg model, make edible nests, test out various types of beaks, compare bird bones with mammal bones, examine various feathers, dissect a gizzard, sing a song about bird traits, and more! My lessons are geared toward 3rd-4th grade level children and their siblings. These are lessons I created to do with a weekly homeschool co-op. We meet each week for 2 1/2 hours and have 11 children between the ages of 0-13. Use these fun lessons with your classroom, family, after school program, or co-op!

Types of Bird Beaks Activity

Introduction, Review, and General Bird Traits

1. Stretch by pretending to fly: arms are straight out and go up, then slightly forward, and then down again. Arms should not ever go behind your body. Mention that some hummingbirds flap their wings up to 90 times in 1 second. See how many they can flap their arms in 1 second.

2. Pray. Discuss orderliness. Review songs.

3. Ask children if they can remember any verses or stories in the Bible that mention birds. In Matthew 6:26 Jesus said, "Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?"

  • Do birds seem to worry quite a bit? (No) Why not? (God takes care of them & provides for them.) Who provides for them? (God) Does God also provide for you? (Yes)
  • When you notice birds, take the time to thank God for providing for you and also remember that He does care for you and is taking care of you.

4. Read a book about birds: "Birds: Winged and Feathered Animals" by Suzanne Slade. While reading, pass around a ping pong type ball to compare with the weight of the lightest bird & a small jellybean to compare with a hummingbird egg, the smallest egg.


  • "Birds: Winged and Feathered Animals" by Suzanne Slade or other book giving an overview of birds
  • a ping pong type ball
  • a jellybean

Monocular vision

5. Discuss the sense of sight for birds. Options to mention:

  • They have the best eyesight of all of God’s creations. Eagles can see a crouching hare a mile away. Some owls can see in dim moonlight as well as you can in the day.
  • Their eyes are huge compared to their heads. God designed their brains to be positioned further back in in their skull & tilted to make more room for their eyes.
  • Have you noticed that birds have to turn their heads to look at an object? That is because their eyes aren’t able to move very much. Keep your head still but move your eyes around in a circle. Birds can't do that. They have limited mobility of their eyes, so God gave them very flexible necks. Owls can move their heads 180 degrees without moving their bodies.
  • Monocular vision: Some birds have eyes on the sides of their heads to detect danger. Do all birds have monocular vision. (No)
  • Which birds have binocular vision, meaning both eyes are in the front? (Birds of prey & other birds that are predatory) They have a narrower field of vision but keener at long range & improved depth perception
  • Have the students stand up at their seats, close their right eye, and try to toss around 1-3 tennis balls. How did only using 1 eye affect your ability to catch the ball? (It affects your depth perception.) Why do you think God gave predatory birds binocular vision?
  • Birds do have amazing eyesight. They can see a greater range of the color spectrum than we can and some can focus on two different objects out of each eye. Each of their eyes has 2 foveae (the part of the retina which “sees” most clearly).


  • at least 1 tennis ball

6. Compare hands and arms to types of feathers by using the illustration from "Birds: Nature's Magnificent Flying Machines" by Caroline Arnold.

7. Examine & compare feathers.

  • What is unique only to birds? (feathers)
  • How do feathers help birds? (allow to fly, insulate, protect, form shape [smooth & streamlined]
  • How many feathers do you think birds have? (up to 3000 feathers)
  • Pass out various feathers. What do you notice about them?
  • Compare contour and down feathers. Point out the rachis, shaft/quill, vane, barb, & barbules. If possible, compare the feathers of a hen and rooster.
  • The contour feathers are strong and found all over the bird. They point toward the tail to aid in streamlining. Some contour feathers are flight feathers which provide the wing shape for flight.
  • Down feathers provide insulation. How do they feel? (soft & fluffy) Are they heavy? (No, they provide insulation without significant weight). Do you know what temperature our bodies maintain? (98.6 degrees Fahrenheit.) The insulation feathers help maintain a body temperature for birds of 110 degrees Fahrenheit -- even when they are in really cold temperatures.
  • The shaft is like the backbone with thousands of bards zipped by tiny hooks called barbules.
  • Look at the feathers with magnifying glasses. What do you notice?
  • Open an umbrella. If you carry an umbrella on a windy day, which catches more wind: the under or top side? Why is this? Does the curved surface of the wing act the same way? Look at a wing feather. Are the barbs as long on one side of the quill as on the other? Do they lie at the same angle from the quill on both sides? If not, why?
  • Which side of the quill lies on the outer side and which is on the inner side of the wing? Is the quill of the feather curved?
  • Press a tip of the quill against your hand. Which way does it bend more easily, toward the convex or concave side? What has this to do with the flight of the bird? If the bird flies by pressing the wings against the air on the down stroke, why does it not push itself downward with its wings on the upstroke?
  • What is the shape and arrangement of the feathers which prevents pushing the bird back to earth when it lifts it wings?
  • Why do you have a rudder on a boat? Do you think a bird could sail through the air without something to steer with? What is the bird's rudder?
  • Does a hen when she flies keep her tail closed or open like a fan?
  • Compare a tail feather with a wing feather and describe the difference. (These questions are from "Handbook of Nature Study.")


  • a variety of feathers: contour feathers, down feathers, tail feathers, wing feathers, hen feathers, rooster feathers
  • an umbrella
  • magnifying glasses
Preening feathers activity

Preening feathers activity


8. Discuss preening.

  • Ask who has seen birds clean themselves. Feathers protect birds' skin and keep them warm, so they have to take care of them. Birds clean their feathers by preening.
  • Who knows how many neck bones we have. (7) To help preen, God gave most birds 13-25 neck vertebrae, more than any other animal.
  • They run each feather through their beak which straightens the feathers kind of like when you have to straighten and clean the Velcro. The barbs and barbules fit together like Velcro. Run your fingers across the feather and try to separate the barbs and barbules. Now rub your finger over it and try to have them fit back together.
  • Another thing they do when they preen is to coat their feathers with a light layer of oil from their oil or uropygial gland (at the base of their rump above their tail). This is especially helpful for water birds. The oil keeps the feathers dry and light. Sometimes you can see birds preening, similar to a cat or dog licking their fur.
  • Pour a little bit of water on a paper towel. What happens? The paper towel gets soaked. What would happen if that happened to a bird when it was flying? (It wouldn't be able to fly.) What do you think will happen when we pour water on contour feathers? [Allow students to work in groups to pour a little water over the feather. Have paper towels under them.] What happened? (It just slid right off and doesn't even feel wet.)
  • That's not all that the oil gland does. The oil also inhibits the growth of bacteria and fungus, contains a Vitamin D precursor that changes into Vitamin D, and preserves the protein (keratin) in the feathers.


  • Velcro (we used the Velcro straps on shoes or backpacks)
  • contour feathers for each group of 3-5 students
  • water
  • paper towels
Chicken bone

Chicken bone


9. Another way that God made birds light enough to fly is by His special design of their bones. Compare a chicken bone to a cow bone (like from a T-bone steak) or other mammal.

  • Look at the bird skeleton picture in the book.
  • How do you think bird bones compare to human or mammal bones?
  • Bird bones are lightweight, usually hollow, & strengthened by cross bracing like steel girders. Why? Reduce weight + Increase strength = Fly
  • Flightless birds, however, have solid bones.
  • Pass around cleaned bones from a bird. If you have a steak bone, pass that around for comparison.
  • What do you notice about them? (They're very light)
  • Break them open. What do you notice? (They're almost completely hollow with a spongy-looking inside. They're also pretty strong for being so light.)


  • cleaned bird bones (such as ones from a Thanksgiving turkey or from a fried chicken meal)
  • steak bone from a T-bone steak or soup bone (optional)
  • magnifying glasses (optional)

Holding a bird

10. (Optional): If you have one, pass around a bird so children can feel how light it is. We had a dead sparrow that we passed around in a clear plastic bag. Another family brought a stuffed pheasant. If you have a friendly pet bird, you can let children hold it.


  • a real bird (in the past people have brought pet chickens, parakeets, & a pigeon)

Crops & Gizzards

11. Discuss the digestive system for birds:

  • Flying requires lots of energy = lots of calories = Might eat body weight in food each day
  • Digest rapidly. They don’t store much solid or liquid waste because would add weight. Who's seen bird poop? It's more liquid than solid, isn't it? That's because it's passing through quickly.
  • 2 important parts we don't have: crop & gizzard
  • CROP - storage sac in esophagus - moistens food & releases it in steam stream to digestive system
  • Do birds have teeth? How do they grind up their food? God gave them a GIZZARD. It's in the stomach & grinds food to make it more easily absorbed in intestine. Yes, they only have 1 intestine (not 2 like us & mammals)
  • Sometimes birds swallow gritty material like sand or gravel to help with grinding.
  • Cut open a chicken gizzard (or a few of them) and let the children feel how tough the inner lining is.

    • Note: In the past I have allowed my children and students to dissect the gizzards themselves. A gizzard isn't too exciting as there is not much to see. The children usually enjoy dissecting them nonetheless. If you're not limited by time, you can pass ones out for every group to dissect themselves.
    • If anyone is wondering, my students who have eaten chicken gizzards said they taste like liver (not at all like chicken) and are very tasty. I sent home the leftovers with a student to use for fishing as they make great bait.
  • Everyone can wash their hands.


  • at least one children gizzard or one for each group of 4-5 children if you'd like for them to dissect them themselves (Turkey or chicken gizzards can be bought from the grocery story alone or in a package inside a whole cooking bird.)
  • Disposable hard plastic plate(s)
  • scissors and/or knife
  • disposable gloves (optional)
Looking at a quail egg

Looking at a quail egg


12. Show pictures of eggs from "An Egg is Quiet" by Dianna Aston.

  • Ask why they might be colored in the various ways. (Camouflage)
  • Ask why some might be more pointy in shape. (So they won't roll off a cliff.)
  • If you have them, pass around wild bird eggs.
  • Show the picture of the development of a baby bird in the egg.


  • "An Egg is Quiet" by Dianna Aston or other book on eggs
  • Wild bird eggs (such as robin egg halves) (optional)

13. Ask the children to name the parts of an egg. They will probably name the shell, white, and yolk. Crack open a hard-boiled egg. Point out the inner shell membrane and the air pocket.


  • a hard-boiled egg and a plate
Egg model

Egg Model

14. Discuss parts of an egg: amnion, yolk sac, allantois, chorion, albumen, shell membranes, & shell. Make a model. As you make each part, discuss the function of it.

  • Paint the inside of a plastic Easter egg with white paint. This is the outer shell membrane.
  • Press a piece of tissue paper inside each piece of the shell. This is the inner shell membrane.
  • Shape a tiny piece of play dough into a bird embryo. (Any shape is fine).
  • Use 2 small different colored water balloons for the allantois and yolk sac.
  • Stick the balloons into 1 side of the play dough embryo. The embryo now has allantoises and a yolk sac.
  • Place the play dough embryo within the bag labeled "amnion" so that the bag covers the embryo and just the necks of the balloons.
  • Lightly press the plastic against the clay so that it doesn't slip.
  • Place the amnion, embryo, allantois, and yolk sac within the "Chorion" bag.
  • Place everything into the bigger half of the shell and close.
  • Use a Sharpie marker or crayon to draw dots (pores) on the outside of the shell.

(You can get the explanations and illustrations from NatureScope's "Birds, Birds, Birds.")


1 plastic Easter eggs, 2 pieces of white tissue paper that have been cut into small circles that would fit inside the plastic eggs, play dough or clay, 2 water balloons (need to be at least 2 different colors), 2 sandwich or snack bags, white paint, 1 paintbrush, 1 crayon, & 1 permanent marker (optional)

Examining a nest

Examining a nest


15. (Optional) Discuss various types of bird nests the students have seen. Pass around one. Have the children note what the bird used to make the nest.


  • a bird nest (Do note that birds sometimes return to the nest every year, so an abandoned nest doesn't mean that it will always be abandoned. The nest I had was one a wren built in our garage. After the birds and chicks left, we removed the nest.)
Edible bird nest

Edible Bird Nests

16. Make Edible Bird Nests.

  • Make your "mud": Combine sweetened condensed milk and chocolate chips in a large bowl and microwave for 1 1/2 minutes or until chocolate is melted. (Stir it first to check before microwaving it longer.)
  • Have children each take a handful of chow mein noodles (twigs) and dump them into the mud. Mix it around until the chow main noodle "twigs" are covered in chocolate "mud".
  • Pass out a sheet of wax paper to each child and spray their hands with non-stick cooking spray.
  • Dump a large spoonful of the nest mixture onto each child's wax paper sheet and have them shape it into a bowl and then press down the middle to make a cup shape.
  • Then let them place 5 jelly bean "eggs" into their next. Set these aside to dry.


  • 1 (14 ounce can) sweetened condensed milk
  • 1 (12 ounce) bag chocolate chips
  • 1 bag (10-12 ounces) chow mein noodles
  • small sheets of wax paper
  • non-stick cooking spray
  • 5 jelly beans per child (If you're doing this around Easter, you can find Speckled Bird Egg jelly beans, which look like bird eggs. As of me writing this, they cost $1.22 at Walmart for a 10 ounce bag.)
  • mixing spoon

Feet & Beaks

17. Quickly introduce different types of birds (birds of prey/raptors, songbirds, water birds, etc.). Show a picture of various bird's feet and ask children what type of bird would go with each type of foot.

18. Discuss various types of beaks:

  • God didn't create hummingbirds to gobble up mice nor did He design hawks to slurp nectar from a flower. God gave each type of bird a special beak and tongue perfect for eating a certain type of food. A bird's beak is frequently a good indication of its diet.
  • You're going to find out which beaks are best for scooping, cracking, and picking by going to different stations and trying to find out which tools go with which types of "food".
  • Give each student a Fit the Bill worksheet.
  • At the front set out a set of beak options (straw, chopsticks, nutcracker or pliers, large scoop or slotted spoon, envelope, tweezers, strainer, & tongs) and bird foods:
  1. Water in a tall, thin vase or bottle (hummingbird and nectar = straw)
  2. Bowl filled with dry oatmeal or chocolate pudding with gummy worms on the bottom to represent worms buried in the mud (curlews and snipes = chopsticks)
  3. Whole walnuts or other nuts with shells to represent seeds with hard coverings (sparrows, grosbeaks and other finch-like birds = nutcracker or pliers)
  4. Styrofoam chunks or soap floating in a bowl filled with water to represent fish and other aquatic animals (pelicans = large scoop or slotted spoon)
  5. Popcorn, tiny marshmallows, or cereal tossed in the air (done by another student), which must be caught in the air to represent flying insects (nighthawks and whippoorwills = envelope or small fishnet)
  6. Rice or puffed rice spread on a log to represent insects (warblers = tweezers)
  7. Puffed rice spread in a bowl of water to represent tiny aquatic plants and animals (flamingos and some ducks = strainer)
  8. Fruit or fruit flavored candies in a bag to represent fruit in a tree (toucan = tongs)
  • Allow 7 volunteers to come up and each match up a "beak" with a food. (If desired, set up these stations for each group of students as they really enjoyed getting to do this.)
  • Have the children mark the answers on their worksheets.


  • a Fill the Bill worksheet for each student
  • 1 set of "beaks" for the class or 1 set per group of students: straw, chopsticks, nutcracker or pliers, large scoop or slotted spoon, envelope, tweezers, strainer, & tongs
  • 1 set of "bird food" for the class or 1 set per group of students (listed above)
Making pine cone bird feeders using pine cones, peanut butter, bird seed, & yard

Making pine cone bird feeders using pine cones, peanut butter, bird seed, & yard

Bird Feeder & Review

19. Make a bird feeder. Do this outside for easy clean-up. (Also check for peanut allergies before doing this!)

  • Have each child write their name on sheet of paper and then place the sheet of paper in a plastic grocery store bag with their name facing outward. This will be used so that they can tell which bird feeder is theirs.
  • Have children tie a string to the top of a pine cone.
  • Use a plastic knife to spread peanut butter over the pine cone.
  • Use a cup full of birdseed to sprinkle over the pine cone. Do this over a bucket or large plastic container in order to catch the loose birdseed.
  • Place the bird feeder on the sheet of paper. Have children place their bird feeder in the plastic bag and then allow children to wash their hands.
  • Do not leave these outside if you live in an area that has ants.


  • sheet of paper,
  • grocery store plastic bag,
  • pine cone (the larger the better),
  • plastic knife,
  • piece of 2' string or yarn
  • peanut butter
  • bird seed
  • For the group: markers & a large plastic container or bucket for collecting bird seed

20. Review what we learned today.


Optional Homework: Chicken

During the week, children can examine a bird up close by using a whole cooking chicken, which is basically only missing the feathers, head, and feet. Have the children try to figure out where the feet & head had been and which way would have been the back and which would have been the breast side of the chicken. If desired, you can also pull out the bag inside and sort through what is there. You can also discuss what the bump are on the skin. After examining the raw chicken, prepare it for dinner using your preferred method. (We used the crock-pot and a dry seasoning mix.) After the chicken has been cooked and cooled, allow the children to help remove the meat from the bones. Save the bones and see how much of the chicken skeleton they can reassemble. (Clean the bones using warm, soapy water or bleach first to make it a bit less messy.)

YOU WILL NEED: 1 cooking chicken
