This class explores the category system supplied to identify animals. Most kids are fascinated through animals and also often have an pet that is a certain favorite, possibly also an pet the child has actually never seen before. Children likewise like to order and also sort things, and this class melds both of these interests.
You are watching: If two organisms are members of the same phylum, then they must also be members of the same
This class is especially designed to move quickly past the expertise level come high-level thinking. This lesson can be taught to whole classroom or offered as a self-directed expansion activity.Learning ObjectivesAfter completing the lessons in this unit, students will certainly be able to:Know and also understand the 7 levels of classification.Apply that understanding as they exercise classifying animals.Evaluate and also compare the group of animals.Devise a category system because that the objects in your homes.Create a brand-new species and classify it follow to the principles of classification.PreparationPrint the lesson arrangement on a shade printer.Have access to the internet for student(s).Gather supplies consisting of paper, pen or pencil, crayons, fancy pencils and/or fine-tip markers.
Lesson 1: Beginnings
Look at the images of this animals, then to fill in the chart below: (We’ve provided you one example.)
Choose the two pets from your chart the you think space most comparable and justify your selection in one sentence.
Lesson 2: arranging the pets — how it happened
Back in the 18th century, a Swedish guy named Carolus Linnaeus assumed it was essential to organize living things, and also he occurred a system to do just that. He started out interested in plants, yet he ended up ordering all life together he knew it. We still usage the essence of his system today. Scientists are continuous refining the system based on brand-new knowledge. Who knows? maybe you will make a readjust in how pets are organized!
Putting pets in order favor this is called taxonomy. The taxonomists — civilization who name pets — usage a publication called the global Code that Zoological Nomenclature, or ICZN, come tell castle the rules for classifying animals.
Linnaeus’s system has seven levels:KingdomPhylumClassOrderFamilyGenusSpecies
Every animal on the planet, down to the many microscopic creature you deserve to imagine, can be classified follow to this system. You have the right to remember the order the device comes in with among the following phrases. The an initial letter of each word is the very first letter the the level of classification. Pick the one you favor the best and practice saying it five times.King Phillip, come out, for goodness’ sake!King penguins congregate on frozen ground sometimes.Keep ponds clean or frogs get sick.
Let’s look at each level and an instance using one common animal.
These levels start out generally — that way the height levels have actually the most animals, and also they acquire narrower and narrower as you go down. So, by the time you obtain to the species, over there is just one animal in the group. You can imagine this levels together an upside-down triangle.KingdomGenerally, scientists agree there are six kingdoms. The animal kingdom (called Kingdom Animalia) is just one of those. In instance you’re interested, the others are Achaebacteria, Eubacteria, Protists, Fungi and Plants. Originally, Linnaeus only figured out two kingdoms: plant and animal. Some scientists think the viruses should have their own kingdom, but at this time they space not contained under this system.PhylumWithin the animal kingdom, the pets are split into much more than 30 phyla (which is the many of “phylum”). You can be interested in Phylum Chordata — it’s the one humans and all animals with backbones space in (do friend see how “chordata” looks choose the native “cord” — prefer spinal cord?). Phylum Arthropoda contains insects, spiders and other animals with segmented bodies, like shrimp. Arthropods have their skeletons ~ above the external of your bodies (think of the difficult shell of a lobster) and also other characteristics in common.ClassThe third level of category is class. For example, Phylum Chordata has actually classes in it like birds, mammals (Mammalia) and also reptiles.OrderThe next level, or rank, is order. Orders room smaller teams within the different classes. Lepidoptera is the stimulate of moths and also butterflies. Carnivora is the order within Mammalia that has actually the most diversity in pet size.FamilyThe fifth rank of group is family. (When you gain to this rank, people sometimes disagree around which household an animal belongs to, so friend may uncover that different sources phone call you various things. This can also happen through orders.) The household for dog is Canidae.GenusThis rank looks like “genius,” doesn’t it? It’s the second-to-last rank, and a genus may have actually only one or two pets in it. If pets are in the exact same genus, they are really closely related. In fact, you might not have the ability to tell castle apart simply by looking in ~ them! once we compose the surname of the genus, us capitalize it and also italicize it. For example, the genus of dogs (and wolves, too!) is Canis.SpeciesIf animals can breed together successfully, they are a species. Once an animal is called by its clinical name, then that method it is being established by that genus and species. We usage a small letter letter and italics for the species. The scientific name of dogs is Canis familiaris; however, the scientific name of wolves is Canis lupus.
Lesson 3: utilizing what you’ve learned
Look ago at your chart of the pets that you did in great 1. Let’s see exactly how they fit into what we’ve simply learned. Utilizing that chart and also the chart on the last page of this lesson, prize the following questions:
Did you placed the genus very first with a capital letter? an excellent for you! as soon as you watch a species’ surname written, it will be the genus and the species, so the scientific name is sometimes just referred to as "species." occasionally the genus will just be detailed as a resources letter with a duration after it, favor this: B. Musculus.
Lesson 4: Working v your favorite animal
Go come the college of Michigan Museum of Zoology’s animal Diversity Web. In the find box, placed in her favorite animal. Currently write out its classification:Kingdom: _______________Phylum: _______________Class: _______________Order: _______________Family: _______________Genus: _______________Species: _______________
Look on the chart of pets in the ahead lesson. Space there any pets on the graph in the exact same phylum together your animal? exact same class? Which pet do you think is the most carefully related to your animal?
Go earlier to the website and try to think of a couple of animals that would certainly be really closely concerned the very first animal friend chose and also classified above. Because that example, if you chose “tiger,“ try “lion“ and “panther.“ how close deserve to you get? have the right to you acquire down to the very same family? How about genus?
What animal could you find that to be closest to yours?
Lesson 5: Classifying her house
It’s not just pets that acquire organized. Think about the grocery store store; is the cereal in the exact same area together the fruit? No, each form of food is in its own space. Girlfriend can easily tell exactly how the grocery keep classifies the items because that sale by looking at the signs over the aisles.
Now think about your house. Imagine the you required to divide every items in her house. One way would be to use the concepts that Linnaeus had actually — to begin out with broad categories and get narrower. Let’s shot it!
You space going to devise a seven-level system for classifying the things in your house. If friend get puzzled at any kind of time as you space doing this, you have the right to look at the examples provided later in the lesson.
Look here for ideas if you obtain confused. There is an instance of exactly how to break things down into smaller categories, and then there is an instance of a scientific category for one item. So that you don’t gain stuck trying come copy the example, we’ve offered a school rather of a residence for the example.
Do you see how the groups obtain smaller and also smaller, finishing in a single item? that is what you room trying come do.
|Species:||"Tales that a 4th Grade Nothing"|
Here is an instance of how one level could be damaged down into several smaller categories. We’ll usage the level family members from over for our example. Notification how every genus is a smaller component of the family of Books.
Lesson 6: Create and classify your own animal
Imagine that you are a biologist studying pets in the wild. One day, while lying in her viewing spot, you see an animal you have actually never seen before. Girlfriend rush back to your tent and also look v your encyclopedia of animals, growing more and an ext excited together you realize that you have discovered a new species! as the discoverer the this new species, you acquire the respect of naming it. Of course, gift a terrific scientist, you will certainly follow the category system in place. That means that the only component of the animal’s surname you will consist of yourself is the actual types name.
You go ago to the animal Diversity web to uncover the closest pet you can uncover to the one you discovered. For example, if the animal you have uncovered looks a lot choose a panther, look up "panther" top top the website.
So acquire a clear snapshot of your animal in your mind. Is it a mammal? a fish? a bird? This works ideal if you develop an animal that is comparable to your favorite animal you decided earlier, yet yet contempt different. Attract a photo of your brand-new animal.
List the animal’s classification. Remember, its classification should be the exact same as the animal you discovered that is almost the very same as this one. The only difference will it is in the species.
Look at several other varieties within the genus so that you deserve to think of something that renders your animal slightly different than any type of other species in the genus. For example, it might be a different shade or eat something various or live top top a different continent.
What is her species’ distinguishing characteristic?
After you have actually classified your animal, including producing a species name, go back and label your snapshot with one thing from every level that is distinct to the classification. Because that example, if your animal is in phylum Chordata, attract a line to the animal’s backbone and write, "Phylum Chordata — backbone." execute this for at least 4 levels. Look earlier to the pet Diversity website you used before to find each the those levels. It will tell friend what qualities are typical of that classification. You may also use an encyclopedia to assist you.
See the example below.
ExtensionBooks top top Animals
Because animals nearly universally interest children, there space myriad publications on them geared to young readers. Included here room a few high-quality volumes that are identified due to high quality of illustration, comprehensiveness of material, interest to gifted learners or standard nature.

AssessmentAnswers to Lesson 3: using what you’ve learnedWhy do you think we left "Kingdom" turn off of the chart? What kingdom does every of these pets belong to?Kingdom to be left off because all animals belong to Kingdom Animalia.Look at the course of the Chilean flamingo. Every birds belong to the class. Carry out you view why we speak to things to carry out with plane "aviation?" utilizing that exact same idea, and looking in ~ the stimulate of the blue whale, have the right to you consist of a indigenous that method "as huge as a whale?"Answers will vary, yet should encompass at the very least the source of "cetacean."Do you agree or disagree through this statement? If two pets are the exact same genus, then they must likewise be the exact same family, order, class, phylum and also kingdom. Why did friend make that choice?Answers will vary, however the exactly answer is "Agree." The category system is optimal down, for this reason if the animal is the same as one more at a reduced level, they must be in the same greater levels.Why execute you think that we had to be an ext specific around the pets in this chart? Why can’t we just put "bear?" Why walk we have to say "grizzly bear?"Again, answers will vary, yet the crucial idea is the there is more than one varieties of bear.Whales actually have actually suborders depending on whether they have actually teeth or baleen. Think about the name of the sort of medical professional who place braces top top people’s teeth. Currently think around the surname of the whale suborder Odontoceti. Execute you think these room whales v teeth or whales with baleen?Suborder Odontoceti room whales with teeth.Write the clinical names the the cow, the flamingo and also the whale.
