Term 1 Science 8 | Lesson 6: Classification of Humans (Full Discussion | MATATAG Curriculum)

0:00 Welcome grade 8. It's me again, Sir Wi. You're ever curious, sometimes funny, always ready, science, buddy. So before we jump into today's lesson, don't forget to like, share, and subscribe. Just kidding. Don't be hard-hearted. It's just one click. If you would like a PowerPoint for the lesson, we have a link in the description. And then there's also the mode of payment, my GCash number. Thank you so much to those who availed themselves of the PowerPoint presentation, to those who supported and believed in the quality of our PowerPoint presentation. Thank you so much teachers. So before we jump into today's lesson, um just a reminder that this is a continuation of the previous discussion lesson 5, the classification

0:47 system. Okay. So, this isn't just a lecture, there are interactive activities that are definitely more exciting than res. So let's grab a pen, turn on our brains, and let's learn together while enjoying our discussion today. There you go. So for the learning competency, the student will explain why humans are classified under the class mammals and the order primates. So in lesson 5, our focus is the domain and then the kingdom. Okay, we discuss the three domain system and then we also discuss the six kingdoms. And I hope that you somehow grasp the things that are necessary for this lesson.

1:34 So it's easy to identify the kingdoms, the domains because each group has specific characteristics , what? There you go. So here okay in today's lesson we will only focus on classmammalia and order primates but of course we will still completely classify the taxonomic rank of humans. So for the learning objectives discuss similarities and differences differences among individuals emphasizing the diversity within human species. The second one categorizes human organisms according to their taxonomic hierarchy. understand the traits of primates and explore why humans are classified within this category. Okay? So even though it's not mentioned in the learning objectives,

2:22 we'll still highlight it because that's what our LCS is. Okay? So I just got these learning objectives from our lesson exemplar. Okay. Mostly in our Lazan exemplar that was given, there are activities that I actually notify to make it easier for the children to understand what our LC is or to master it. So before we continue, let's have a short review. Okay. Who can name all the taxonomic ranks in the correct order from the biggest group down to the smallest? Okay. So volunteer. Okay. That's right. The first one we have the main. Okay. Second, we have a kingdom. The third one is phylum.

3:09 Okay, next we have class, then order, family, genus and the species. Okay, that's correct. So, it's funny because we were able to recall this taxonomic rank or complete taxonomic rank. Who invented this or introduced it to us? Okay, okay? Who? Carlos Leneas. Okay. So, thank you. And Carolus Leneus introduced us to binomial nomenclature, which is what we use to name organisms. So there are two epithets, the genus and the species. What.

3:57 There you go. So each organism just remember that they have specific scientific names and that is their most international name or the standard name. Okay? So our scientific names are written in Latin. Okay? If you can remember or recall. And then when we write a scientific name, if it is typed, it should be italicized. The first letter of the genus is capitalized and then our species is in lower case. What? And then if we write the handren, make sure our genus and the species are underlined separately. But still similar, the first word or first letter of our genus is capitalized. And then

4:43 our species is in lower case . Okay? So hopefully we have that simple instruction. There you go. So are you ready for our first activity? Are you ready? Um uh what do you call this? Flash that complete taxonomic rank system from domain to species. And it is important okay in our first activity. So our activity is the ultimate rank and riddle showdown. So for the objectives, identify and arrange the correct taxonomic classification of humans from domain to species through clues and reads. So we have our PowerPoint presentation today. For instructions, first I will flash several words on the screen related to human taxonomic classification like eucaria, animalia,

5:30 etc. Okay, you are allowed to copy them in your notebook to help you remember it. Okay. There you go. So, I posted it for a while because I remembered that his choices weren't there yet , okay? So, after our instruction, I will flush our choices to the readles. Okay? To make it easier for you, what? So, next instructions. Next we will begin the riddle relay. I will read a read that describes one of the taxonomic levels of humans. Your choices will come from the words I showed earlier. Try to figure out which one matches the readle. The first student or group to give the correct

6:16 answer will receive a prize. Of course, we have a prize. There you go. So, are you guys excited? Okay. So, these are the words or your choices. So, we can copy it into a notebook. First, to make our answer easier. Okay. So are you done or can those watching now take screenshots? There you go. So let's start. Okay. The human taxonomic classification. So in this activity, we will classify our humans from domain to species. What is his specific classification in taxonomy? Okay. So let's start for the domain. There you go. What is the domain of humans? Where does he

7:01 belong? Let's see. So this is the readle. I am a group where cells have a true nucleus inside. Not simple or small but complex and wide. What am I? Okay. What is the domain? Okay. Of the human. So based on the riddle, there is a nucleus in the cell. Which of the three domains? Those with a nucleus in the cell or true nucleus. Okay? Correct. Okay. You are right. So our answer to that is the main eukaryotes. Okay. So, claim your price. So, teachers, you can click claim your price after your answer is revealed. Okay, this is it. There you go. So, this is the prize. Congrats, son, plus one

7:49 on the quiz. But I will change it. Okay. So, in the next lessons, I won't show our prices because I haven't really discussed this with my children yet, because I'm actually only in lesson 5. There you go. So it was published earlier because someone requested for the PowerPoint and for the presentation. I'm glad that someone appreciates it somehow. So next for the kingdom. There you go. So this is the readle. I am a kingdom full of creatures that move and breathe. Not plants or fungi. What am I? Mmm. What is that? A kingdom full of creatures that move. Hmm. Not shop

8:35 blance, not fungjai either. So what is he? So let's see. Okay, correct. It's animal. Okay. So claim your price. So read on. So for our philum, that's what they say, right? I have a backbone or a nerve cord inside supporting the body so you can stand with pride. So our clue there is a backbone. Okay? What is that? Which of the choices is the answer that you feel? Of course you are correct. It's cordata, okay? Or chordates. There you go. So ours or humans belong to the phylum chordates because they have a backbone. And when

9:23 we say chordates are animals that have a backbone or spinal cord. As examples of this, we have fish, frogs, birds and humans. Okay? So if you can stand straight or wiggle, you probably have a backbone. You're a cordate. Okay? So next for our class. Okay? What class does a human belong to? I am warm blooded with hair or fur and feed my babies with milk. Yes, that's who we are. Okay. What is that? What will our answer be in class? He is said to be warm-blooded and feeds on milk. So let's see.

10:09 Okay. That's correct. Mammal. Our children are really good . So just remember in class mammals, one of the unique characteristics of mammals is that they feed their yangs with milk. Okay? So if you ask me if we belong, of course we belong because we're classifying humans today and we are humans. There you go. So next order. What is it? What order should we have? Is this the order from Jollibee at McDonald's? Charing. Okay. So let's read a readle. I am the order with hands that can grip forward facing eyes and big brains that think quickly. Okay? So those are our hands

10:56 that can grip can grip tools or can hold particular things okay to be manipulated. Okay. So we also have forward facing eyes. When we say forward facing eyes, the eyes are placed at the front of the face, not on the side or anywhere else. And then big brains. We have brains. Okay. What order is that? Okay. So let's see. Correct. It's primates. Okay. So next. There you go. for family. What kind of family are we? Okay. What kind of family is that? Is my surname Falkatan included in the human family ? I've said it. Anyway, so

11:41 funny. There you go. So I am the family known as the great apes including humans with upright shapes. Mm. What kind of family is this? Okay. So, great apes, family of great apes are our ancestors. Okay. So, let's see. Correct. It's humanity. Okay. So what is humanity? So this is the family of great apes and yes, we're part of it. It includes humans, chimpanzees, gorillas and orangutans. What. So it's like saying we're all cassins in a big monkey family tree. So but with brains that can solve a particular problem. So are there monkeys that scientists have actually tested to see if

12:27 they can solve particular problems? Especially that chimpanzee is one of the closest organisms to humans. Actually, he has 98 to 99% DNA similarity to humans. Okay? And the chimpanzees, they can recognize themselves in the mirror. Okay. So, next we have the genus. What is the genus of humans? Actually, I already said this in the previous lesson, right? So, let's see the reading. I am the genus that means man or human. Human name. The group where modern humans came. Okay? The meaning of that word is

13:12 man or human. What is he? Okay, correct. It's gay. Okay? So, the genus homo is a group of species that are closely related, which is what the Latin word homo means: man. Okay. So that means homo is a Latin. I said earlier, our scientific names are written in a Latin language. So when you see homo, it means you're in the group of smart humans. Okay? So we also have extinct members of the genus homo. Like for example, I know that in AP, they encountered homo habilis, homo erectus. Okay, those are um what do you call this? Organisms that have the same genus as us. Okay? So finally, we have the

13:57 species. What about us? What species are we? Okay? It said, "I meanwhile and knowing the species name we were the modern human smart and aware." Okay. So what is that? So it's correct wisdom. So when we combine our scientific name for humans, we have homo sapiens. I hope we're okay with the taxonomic classification of humans from domain to species. Again, let's read. What is the domain of humans? Yakaria kingdom animalia phylum cordata class mammalia order primates family huminity genus homo. Species, sapiens. Okay, teachers, don't

14:43 forget to click the price. So I won't go to the clinic for now because my child might watch it and they already know the prices. Okay. Okay . There you go. So let's proceed to activity number two. Okay. So for our next activity I am homo sapiens my human taxonomy ID card. Actually, there are times in our activity one where you can still give or provide guide questions if you have additional discussions there. It's okay. Okay. So what I'm just showing here in the video is the different activities that we um have or possibly have in this lesson. So for our next activity, I am Homo sapiens, my human taxonomy ID card. So for the objectives,

15:30 okay, categorize humans using the correct taxonomic hierarchy from the domain to species. Identify the key characteristics that define humans as a species. So for the materials needed, ID card template. So, managers, can you provide a template for this? Okay? So you can print as many sections as you want, or it would be better if they were all the same. Just provide the format and size of the ID card for the students and then reference charts for human taxonomy. Okay? You too will provide teachers. Pencils or pens, coloring materials, mirror or photo for drawing soul portrait. So here they can use their own pictures or they can also use pictures of artists in magazines. They can

16:17 cut out a picture of their favorite K-pop group or whatever they want. Okay? What do they have the freedom to choose which picture they want to post? It could be themselves, it could be their idols. Okay? So next for the instructions, write your full name on the ID card. Of course, don't forget to write your full name. How can a teacher check that without a name? Fill in the taxonomic classification of humans from domain to species. Answer the guide questions by writing at least three traits or characteristics of humans. Draw a picture of yourself in the box provided. We can attach a photo if we don't know how to draw. Decorate your ID card neatly and creatively.

17:02 Make it your own. So I hope the instructions are clear. There you go. So this is the sample ID card for taxonomic identity of me. There you go. So over there on the side is your picture, your name, your grade and section. at the front. This is our front. Okay? There's our complete taxonomic rank of humans. Okay? Behind the ID, that's where we'll put the human traits. Okay? So here in human traits, you will provide what are the specific or unique characteristics of humans compared to other animals. So so you don't get lost in what's being put there, okay? I have some guiding questions. This is what you can put in the back. guide question on how you will provide the traits of humans. So let's say how do

17:47 humans move. You can put it on the back of your ID card. What makes human hands useful? How do humans communicate? What is special about how humans think? How are humans born or raised? So this is your guide. Okay? I've already suggested that teachers, we can just flash it to the students that they really have advances. But we will also have sections where they can't keep up or are having a hard time. So I just really fluffed it up so they knew or guided them on what to put in the back because they might get confused and wonder what else to put there. Okay? So thank you so

18:34 much for the rubrics of course or the rubric. Let's not forget to flash this to them so they know how to handle them. So this will be the basis for how they will make the ID card. So we have taxonomic classification, human trade section, self portrait or photo, creativity or effort then following instructions. Okay? So a total of 20 points. Okay? It's up to you if you want to change the rubric. Okay? Thank you very much. So okay, after the kids make the ID card, okay? You can collect it and then you can check it. Okay. So let's go for our next activity, activity number three, all aboard a mamal train adventure. Okay? So we are about to meet our

19:20 learning competency. So for objective, identify the common characteristics of mammals. Explain why humans are considered mammals. We have our PowerPoint presentation. And for instruction, travel through each station. Listen carefully or read the description of the seven mammal characters. William meets on his journey. Each station represents a different mammal with unique characteristics. So if we go back to our title, All Aboard a Mammal Train Adventure. So I have a train here with Willy on board. And while he travels, he meets along the way, okay different mammal characters. And they will give a particular description of mamal. Okay. So, step

20:05 two, stamp your journey as you go through each mamal. Right? Down one key characteristics that makes that animal a mammal. So while we're having an adventure, okay? You should have a notebook so you can write down the characteristics we see in a mother. Step three, answer the guide questions and after the journey, reflect and write your answers in complete sentences. Okay. So, are you guys ready? Okay. So, are you ready to travel? There, there . So, all aboard a mamal train adventure. Okay, so let's start. Hey guys, I'm Willy, your friendly train conductor. Let's learn more about mammals as we travel from station to station. Ready? Let's go. There you go. Okay,

20:54 okay. For station one, we have Mr. Bat. So really, while driving through a dark tunnel in a cave, I met Mr. Bat who was hanging upside down. Mr. also said this. Bat, "Hey there, I may have wings, but I'm no bird. I'm warm blooded. I have fur, and I nurse my babies with milk. That makes me a mamal." Okay? So, you can write it down what the characteristics of a mammal are," said Mr. Bat. Okay. So for the second station, okay, Miss Dolphin was there. Will, we crossed an underwater train tunnel and spotted Miss Dolphin jumping through the waves. Okay. Miss Dolphin said, "Hi, Willy. I may swim like a fish, but I breathe air and feed

21:41 my cobbs with milk. I'm warm blooded, too." Yep, I'm a mama. Okay. So, is Miss Dolphin famous. Next. Station 3 Sir Elephant Willy at the grasslands. Sir Elephant greeted us with a loud trumpet. Welcome travelers. I take care of my young, have thick skin and feed them with milk. I'm proud to be a land mammal. Okay? So thank you Mr. Elephant. Okay. So let's see what he said about mamala no. Next for station 4 doggy the pet. Okay. In the village, I met Dog the pet wagging his tail. Okay. Wof. I give

22:27 birth to puppies and take care of them with milk. My furry body keeps me warm. I'm totally a mamal. Okay. I'm totally a mammal. Sige doggy the pet. Okay. So for station 5 nandon naman si Queen Whale. Back in the deep ocean, we wave to Queen Whale. Okay. Sabi naman, "Hello little ones, don't let my size fool you. I breathe air, breathe and have a big heart. Literally, I'm seeing mammal." Okay. So, thank you, Queen Whale. Mama kangaroo is at Station 6, down under in Australia. What a long way to go. What? Mama kangaroo bounced over to say hi and said, "Good day. I curry my baby in my pouch and feed milk until it grows.

23:15 That's what makes me a mamaal. Okay, okay. There you go. So for the final station or the station 7, you the human wily. At the final stop, I looked in the mirror and guess what? It's you. Okay? It's you. Okay? It says, "Humans are mammals too. You're warm blooded. You have hair. You were born alive and as babies. You drank milk ' ba? Amazing right? Okay. So I hope that you enjoy the simple travel or um adventure of Willly ano. So I'll keep that short because maybe you'll get bored. Okay. So for our guide questions, you can flash this teacher to our kids so that they can um drive their

24:02 curiosity and then check whether they learn something about the um short adventure of ano. So we can put expected answers here. I have provided or we can also randomize for the kids. You can also verify whether it is correct or not ano or guide them. So the first question, what do all the animals in the stations have in common? Okay, correct. They are all mammals. Okay, can you list a at least three characteristics that make an animal a mammal? Okay. I said no, have far or hair. Warm blooded, give birth to live young, fed milk to their babies. Okay. So these three characteristics, children, have fur or hair. It is important for a mammal because

24:47 their fur and hair are important. Because fur especially in lower animals um it helps them regulate body temperature. Okay? Warm blooded. Where are warm blooded? Give birth to life young. Okay? They give birth to life young. They no longer lay eggs. Okay? They are not egg laying. Okay? No more. We are not like that. Okay. So, they carry their babies in their stomachs for about um let's say weeks, months or if it takes several months. Okay? Especially in humans, how many months? 9 months. Okay. And most importantly or most importantly they have the same characteristics. They feed their young with milk. Okay. Really. So mostly mammals or mammals

25:34 actually have mammary glands or the part that produces milk. Okay. There. So next, "Did you notice any differences between the mammals? What are they?" There, it said, "Some live in land, others fly like bots or swim like whales. Some are big, some are small." Okay. So our mammals have different niches or habitats. There is uh land, there is water. Okay? So let's not think that all mammals live on land. Okay? There are also mammals that we see in the ocean, what. So next, why do you think a whale is still considered a mammal even though it lives in water like a fish? Why? So it says there because it breeds air, gives birth to life young and produces milk. Okay 'yun '

26:20 yung pinaka-unique characteristics ng mammal kasi ano next what makes humans part of the mammal group? Can you give proof based on our characteristics? Of course we have hair. We are warm blooded and we produce milk. Okay? So for girls what do we produce milk but we are also mammals boys ha kasi we feed what is ours when we are babies we drink milk what comes from our mother. That's next. Hopefully our guide questions are clear. So this is just what I gave to check whether the students understand or if they have understood in our simple adventure what. So okay we are in the first LCS what. Okay. I'm so excited. So next activity activity number four primates.

27:06 Are we one of them starting game? So here we are in the mata-touch na natin or we are going to hook the LCS. Comprehend comprehended trace of privates and explorer why humans are classified within this category. Okay. So we have materials here. ID card template. Okay. No, no, it's not the materials rather. Okay. I didn't change it. Okay. So, here in our materials needed power just the PowerPoint presentation itself. Okay. So, okay, let's change it. It's easy. Okay, it's just the PowerPoint presentation. But when I sent it to your PowerPoint it was edited. PowerPoint Presentation. I said it's not yet to polish but

27:51 someone called here and requested that hopefully it will be published. There. So anyway, there and for the instruction there the teacher will flash a table showing different characteristics. Students will sort them into three categories. Primate traits, non-priate traits, or could be both. Okay. So go ahead. So these are the examples of characteristics. So let's sort that . That's right? Let's sort him if he's primate, non-primate, could be both. Okay. So let's look. Let 's start with grasping. Grasping hands. When we say grasping hands, they can hold tools, things that we can manipulate. Okay. So

28:39 grasping hands, primate primate straights. Okay. So next shell. We don't have a shell. Those shells are not molk. Okay? Philumoluska. Those can't be primates. What? Those are nonprimate rates . Forward facing eyes. Okay. It could be both. Okay. Because when we say forward facing eyes, the eye is at the front of our face, what. Okay. So, that's possible for others. There are actually primates with forward facing eyes. And there are also non-primate animals with forward facing eyes. Like for example, ah dog cuts. Okay. So, forward. Okay. We didn't say

29:24 forward, the other eye is on the side. Okay. Next. Cold blooded. Aha. We are not cold blooded. Okay? So cold blooded are non primate rates. Because primates are warm blooded nails. Okay? Not closs. Okay? What is that? For primates of course the nails exoskeleton nonprimates. So mostly exoskeletons are seen in the phylum arthropods or our phylum of let's say insects crustations. Okay. Their part or the outermost part of them is the hard or tough one. Okay? But it's not a shell. We call that an exoskeleton. Okay. Long

30:09 gestation period. What is it? When it's a long gestation period, what characteristics or whose characteristics are those? Okay. Is it for primates or ah non-primate rates? What is it? That's it. So what if we say long gestation periods? It's developing or developing the babies. Okay. So, um in primates especially in humans, the development of babies in the womb of the mother, it takes 9 months. Okay? And in other mammals it is longer especially in elephants, what is the length. Okay. There. So our long gestation

30:56 period could be both. Okay? So that could be a trait of non-primates too. Like for example elephants, okay? Their gestation period is also long. What I told you earlier. What next? There. That's a non primate race. Of course we don't have BK. What? We have beak lives in groups could be both. Because there are non-primates that what do you call this? Live in the jungle or in the forest in groups. Like for example lion okay call pride okay so mostly the monkeys also they live in

31:42 groups. There. So next could be both monkeys primates. Is our lion nonpriates. So could be both feathers. Non primates because feathers are in birds in the class avis . Okay so we don't have feathers. There. So next, flexible limbs. These are primate straights. We have flexible limbs. Okay, scales of course, nonprimate traits. We don't have scales for this in fish. Social behavior could be both. Okay? It could be in non-priates too because um let's say lions they live in pride or they live in groups. So they have social behavior

32:29 there. Okay. And then web feet. These are primate rates. When we say web feet, these are the ones in ducks, in utters, what else? Okay. In frags, the ones that seem to stick together like they have skin. Okay they stick together. Okay. So those are the web feet non primate that's ours are ours fingers separate. Okay. So next opposite this is the primate rates. Okay. There next. uses tools could be both. Okay? In us here in uses tools, there are nonpriates that can use tools. Like for example, octopus, they can manipulate um tools. The shells that they can manipulate the crow. Okay. I've seen a

33:17 lot of videos for example how they get a particular food in a narrow ah wood. Okay? They use a stick. Okay? So it could be both. Next, flat phase. This is just a primate trace of our flat face. Binacular vision. That, could be both. Okay. Because binacular vision is mostly for nonpriates, they use it for predation. Okay. Next, large brain. Okay, so primate rates. Okay, this is just for primate primates. Next, communicates with sound could be both. 'Aren't there non-primates that can communicate through the use of different sounds. What next? Needs air to breathe. Could be both '? Next,

34:05 shoulder rotation. That's primates. Okay. Anthene. So our antenna is non-primitrates. Okay. Our insects mostly have antennas like um what do you call this? Lobster what else? Shrimp. Okay. They also have what . Okay. Next. Uprure. These are primary traits that allow them to stand upright using to fit what. So has emotions. Could be both. That. So of course others have emotions too. We just don't feel what non-priates do. Needs food to survive. Okay. So there. Could be both. All organisms really need it. Cares for young. Of course could be

34:51 both. Okay? Maternal instincts are always there. Nonprimate or primate, maternal instinct is always there. Okay. Animals sleep at night. Okay. So it could be both. Okay. So, next, lay eggs. Nonpriates. We lay eggs. Gills. Okay. So, these are mostly for fish so they can breathe properly. Nonprimates. So, let's sort it out. So, we've got it all. Nonprimates. Primates. Okay. There. So, it's really flashed to all of you. For primate traves, grasping hands with nails, flexible limbs, opposable thumbs, flat face, large brain, shoulder rotation and upright posture. Okay.

35:38 That's it. So okay, next. So for our last activity, that's activity number five. Are we really that different a primate human comparison? So for the objective of this activity to analyze the similarities and differences between humans and other primates by examining physical traits and behaviors. Okay. So for the materials needed Manila paper or cardboard. Okay. So photo animal profile cards. Okay. We have the five of which I have a choice. the panzi gorilla orang baboon and tarer markers or colored pens and then tape so here in the activity teachers this is really a group activity so what I thought here is let's read the instruction students will be

36:25 divided into five groups each group will receive one photo profile card of a primate chimpanze gorilla torsure orangutan or baboon the group will examine the card carefully and then answer the following guide questions written on the board or handout their answer must be written on Manila paper. They will be given 7 minutes to complete the task and present their output in the class afterward. Okay? So these are the photo cards that the children will receive. Okay. So our first photo card is just for group one, group two, group three, group four and group 5. Then afterward, this is what they will answer the guide questions. Okay. So their answers are written on Manila paper

37:11 . That's it. Okay. Okay. So just give them a specific time when they will present it. Okay? So I think it's a bit much what do you call this? 7 minutes is short. But if you really have time, go for it to enhance the critical thinking of our children . So this is the last activity. I won't show you the presentation here because the children will do it. So lastly, have learners takeaways. We don't have a quiz because the quiz is on the exemplar is the same as the quiz in lesson 5. Hopefully you enjoyed the

37:58 activities and for those who want to avail the PowerPoint presentation, okay? I have a link, okay GDrive in the description and then our payment is there. which is very cheap. Php15 only for this presentation. Thank you so much.
