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 3 of a 5 part hands-on unit study on Animals and Zoology. Peel your "skin" like a reptile, dissect a fish, make origami jumping frogs, compare amphibian and reptile eggs by feeling tapioca and grapes, and more as you study Amphibians, Reptiles, and Fish! 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, camp, or co-op!
Introduction, Review, and Animals in Exodus
1. Stretch. Pray.
2. Review classification. If desired, sing first verse of "Six Kingdoms" & "Invertebrates" songs from previous lessons. (Find the links to the previous lessons by going to the section toward the bottom of this page titled "Ready for the next lesson?".)
3. Read about 10 plagues using some of "Exodus from Egypt" by Mary Auld. (Alternatively, you could read the passage from the Bible.) Ask the children to name all the cold-blooded vertebrates or invertebrates mentioned during the plagues. (The staff changes into a reptile [snake]. Fish die from the blood in the Nile River because of the blood. Amphibians [frogs] fill the land.)
Book to Read for Activity 3
Exodus from Egypt by Mary Auld - During the 10 plagues in Egypt, each type animal we are studying (fish, frogs, and snakes) is used or mentioned! This is a longer Bible passage to read than what we normally use in lessons, so I wanted pictures. I love the illustrations in the book as they are more realistic looking (so children will not confuse the story with cartoonish fiction), but they are still soft enough that even younger children will enjoy viewing them. I especially love that it stays consistent with the Biblical account.
4. Quickly discuss the differences between endothermic & ectothermic (warm-blooded & cold-blooded) animals.
5. Read most of "Fish: Finned and Gilled Animals" by Suzanne Slade. While reading, have children open and close their mouths repeatedly to get air, just like the fish do. Briefly mention mouth brooders and have children each hold a handful of "eggs" (jellybeans) in their mouths without biting or swallowing them just like mouth brooders carry eggs in their mouths.
YOU WILL NEED: a bag of jellybeans (at least 100 jellybeans)
Book to read for activity 4: Fish
6. Demonstrate how fish bladders work. God designed fish to have a swim bladder that fills with air when they want to rise in the water, and it lets all the air out when they want to sink in the water. Demonstrate using a balloon and a large bowl of water. Blow up the balloon, and show how the filled "swim bladder" lifts the "fish" up near the surface of the water. Let the air out to show how that allows the fish to sink lower. The air is lighter than water, so it helps the fish to rise when the swim bladder is full. People have used a similar design in submarines.
YOU WILL NEED: a balloon (not inflated) & a bowl of water
Fish Anatomy and Dissection
7. If you have one, watch a fish swim. Talk about its fins. Discuss the anatomy of a fish.
8. Option 1: Dissect fish & review main character traits of a fish. Refer to this fish dissection lesson plan and/or this fish dissection lesson plan to provide you with procedures and questions to ask as you dissect the fish. Option 2: If you'd prefer to avoid a real dissection, you can use the 4D Vision Great White Shark Anatomy Model. Some of the children and families did not want to do a live dissection, so they instead used a 4D model figure. My children love taking this apart and putting it back together. It's over a foot long and has 20 detachable organs and body parts. It's very sturdy. The company also makes a frog anatomy model. http://www.amazon.com/Vision-Great-White-Shark-Anatomy/dp/B001YIT1YI
YOU WILL NEED: 10 extra-small & 3 medium sized pairs of disposable gloves & any sharp cutting tools (sharp kitchen shears work well), 3 hard, disposable plates, and 3 fish (One year we got ours frozen & ungutted from an Asian market. Another year we got some perch from someone's fishing pond.)
9. (Optional) As children finish washing their hands, let them look at fish scale under a microscope and count how old the fish is. Just like trees, fish scales grow a circle for each year a fish is alive. Honestly, we couldn't see any circles on the scales we looked at. I guess we needed a more powerful microscope or a larger fish. It was still neat to see the scale under the microscope anyway, though.
YOU WILL NEED: a microscope and microscope slide
Scales vs. Slime
10. Introduce herpetology: the study of reptiles and amphibians.
11. Scales vs. Slime: Let children touch a piece of clay with rows of shelled sunflower seeds stuck in it and a piece of plastic wrap sprayed with thin layer of non-stick cooking spray. Have children describe how each feels. Which do you they think represents the reptile skin? The amphibian skin? Do let them know this is a generalization because some toads have dry, rough skin & some geckos have smooth skin with inconspicuous scales. (Activity is from "Let's Hear It For Herps!" from the Ranger Rick's NatureScope series.)
YOU WILL NEED: a small plate with a piece of clay with rows of shelled sunflower seeds stuck in it and a small plate with a piece of plastic wrap sprayed with thin layer of non-stick cooking spray
Amphibian vs. Reptile Eggs
12. Let children touch some tapioca that's been sprinkled in a small bowl filled with boiling water and touch a few grapes and/or ping pong balls laid on sand or dirt in a bowl. Have the children describe some of the differences between them. Which do you think reps reptile eggs? Amphibian eggs? Amphibian eggs don't have shells, so they do not have much protection from drying out. Reptile eggs stay moist because they are laid in water or near moist areas on land. They're firm but not brittle (like bird eggs). Reptile eggs can vary. Turtle eggs are round with a smooth shell. Snake eggs are oval & leathery. Most amphibians and reptiles lay eggs, but some do bear live young. (Activity is from "Let's Hear It For Herps!" from the Ranger Rick's NatureScope series.)
YOU WILL NEED: a small bowl with some tapioca that's been sprinkled in a container filled with water and a bowl with a few grapes and/or ping pong balls laid on sand or dirt
13. Read most of "Amphibians: Water-to-Land Animals" by Laura Purdie Salas. When it talks about amphibians' tongues being connected at the front of their mouths, have the children stick out their tongues and see where theirs is connected. Observe the person's tongue next to you to see where their tongue is connected. Ask, "Why do you think God created amphibians' tongues to be connected at the front instead of the back?"
14. Quickly look at pictures in "Amphibian" by Barry Clarke (or look at pictures from a laptop). It includes pictures of fossilized amphibians. It says they're millions of years old, but they're really just great evidence of the flood during the time of Noah.
Book we used for activity 13: Amphibians
15. (Optional) If you have them, let children pet or look at a live frog. We also passed around a preserved toad.
16. Make an origami jumping frog. Use these directions or any other you prefer. (If doing this with younger children, pre-fold the paper and then unfold it again. Let the young children re-fold the paper using the creased lines as their guide.)
YOU WILL NEED: 10 pieces of paper & 1 pre-made model
17. Read "Growing Frogs" by Vivian French.
Book to read for activity 17: Frogs
18. (Optional) Pass around a snake skin and/or a pet snake. Ask what we'll study next. Point out the difference between the upper scales and lower scales. Ask why they think God made them that way. (The design of the lower scale allows them to climb and move. The upper scales are like armor to protect it from predators.) *If children do handle a live snake, make sure they wash their hands afterward.
YOU WILL NEED: snake skin and/or a pet snake
Book option to read for activity 19: Reptiles
Book option to read if you have younger children (preschool and kindergarten aged)
19. Squirt a small amount of liquid Elmer's glue on the back of each child's hand and tell them to smooth it out so that it is in a thin layer. Tell them to leave it there to dry.
-Read most of "Reptiles: Scaly-skinned Animals" by Laura Purdie Salas or "Miles and Miles of Reptiles: All About Reptiles" by Tish Rabe. While reading:
-Tell children that gecko lizards can clean their eyeballs with their tongues. Ask them what they can reach with their tongues.
-Mention that snakes shed their skin by rubbing their bodies against rocks or other surfaces. First give them a small amount of Elmer's glue on the backs of their hands and have them rub it around to make a thin layer. Let it dry.
-While glue is drying, have children try to take off their sock without using their hands. They can rub their foot along the carpet.
YOU WILL NEED: extra children's socks (or just tell everyone to bring a sock for each child) and Elmer's glue
20. Quickly look through some of the pictures in "Eyewitness: Reptile" by: Colin McCarthy (or just look at photos from a laptop). Again, fossilized reptiles are not millions of years old. They're really just great evidence of the flood during the time of Noah.
Reptiles and Review
21. (Optional) Let children observe, pet, and discuss more about lizards. (We used anole and fence lizards that one family caught for the day. They wore gloves when handling them since they do nip occasionally.)
22. (Optional) Sing "Cold-blooded Vertebrae" song. (Tune: When Johnny Comes Marching Home) from From "Lyrical Life Science Volume 1"
YOU WILL NEED: words to the song printed out
23. (Optional) If you are not limited by time, allow children to select an amphibian, a fish, or a reptile from "Draw Write Now, Book 6: Animals Habitats -- On Land, Pond & Rivers, Oceans" (Draw-Write-Now) and draw it.
YOU WILL NEED: paper, pencils, and crayons
24. Review what we learned.
CD we used for activity 22: Lyrical Life Science
Lyrical Life Science, Volume 1 Audio CD (found using the amazon.com ASIN code: 0964636778) is a wonderful CD! We love this series that introduces science using catchy tunes that are jam-packed with factual information. My children love singing the coldblooded vertebrate song from this! We also use the accompanying book with line drawings and much more information of all the animals by classes and orders. This particular CD includes the scientific method, characteristics of all living things, vascular plants, algae, fungi and non vascular plants, invertebrates, coldblooded vertebrates, birds, and several types of microscopic organisms. You can download indiviual songs from amazon.com if you would like to just get the one for coldblooded vertebrates.
Handwriting Book We Used For Activity 23
I love incorporating as many subjects as I can when doing unit studies. Draw Write Now, Book 6: Animals Habitats -- On Land, Pond & Rivers, Oceans (Draw-Write-Now) by Marie Hablitzel is a great handwriting lesson book (ideal for Kindergarten/1st grade level), and it also includes wonderful drawing lessons of animals that both young and older children can easily follow with success. This isn't a picture book to read; instead, it's an art and handwriting book. We used it for drawing pictures of reptiles and amphibians. It has simple step-by-step directions to draw a frog, lizard, alligator, and more. Even my 4 year old can successfully follow the directions alongside my 8 year old. It also includes a brief handwriting lesson and the creature, which I use for my 4 year old's handwriting practice.
Below are the lapbook pages you can print out and have your child complete to review the information we learned at co-op. Children will be able to show off their completed lapbooks at our end of the unit presentations. Feel free to add more or less that the below links.

Audio Story We Used For This Lesson to Learn More About Fish
The Voyage Beyond (Jonathan Park Radio Drama) Audio CD by Pat Roy and Douglas W. Phillips - My entire family loves this extremely well-done Christian audio drama. We own the entire series and have listened to them numerous times. In this volume Jonathan Park and his family explore the depths of the ocean and see the marvelous designs of our Creator in the fish of the ocean and many other unique sea creatures...amidst the many exciting twists and turns in the face-paced plot. This mentions quite a bit about the classification of fish.
