Yes, Tutor Anne, let's give a shout out to the students all over the Philippines who are watching right now so that the learning can continue even though our situation is like this right now. Yes, Tutor Abe, despite our situation, even the students are fighting. We'd like to inform everyone that you may share this online tutorial and the students who are not able to watch it now for some reason, maybe because of the internet connection, they may revisit this, they may use this platform. for uh to help them for their asynchronous learning okay so they may revisit the facebook page of DepEd EdTech Unit and DepEd Tayo also sa youtube channel and DepEd EdTech Unit DepEd Philippines and DepEd TV okay pero bago tayo mag start shout out muna ako so let uh let me take this opportunity shout out muna ako sa aming schools division superintendent ng STO Las Piñas Dr. Joel Titore Campos SESU 6 Our Education Program Supervisor of Junior High School and Senior High School, Dr. Raquel Emaustero, and our Principal of Las Piñas National High School, Mr. Ignacio Elson Jr.
And to my co-teachers, who are also continuing their education for the children of Las Piñas National High School, both Junior High School and Senior High School. I just want to say, Dr. Abe, a shout-out to the Program Implementation Committee of Brigada Escuela of our school, because we also completed the webinar series for our... Okay, so, of course, I'm also a tutor. Shout-out to our School Division Superintendent of SBO, Paranaque, Ma'am Evangeline P. Ladines, SESO 5. To our Dynamic Principal, of course, Sir Jerry A. Lumaban. And, of course, to my very supportive Department Head, Ma'am Rowena M. Reyes.
And shout-out to the teachers of Paranaque National High School, Maine. Yes, thank you for letting us do this. advocacy para makatulong despite our situation.
Kaya naman, let's start this tutorial with this question. Sa importante, tutorial na pinag-uusapan natin ito. How do you care sanity?
So, teachers, students, parents, dapat nangangamusta tayo. So, we must set our perspective right. Nakalagay dyan sa nabasa ko one time, Monday won't be so gloomy when you believe that something good is about to happen.
So, positive vibes so you will also magnet positivity around you so let's hear from our tutis from what place basila para alam natin kung gaano kalayo na bang nararating ng ating online tutorial na ito and you if you want to answer our question how do you keep your sanity you may type in your answer and also include the name of your school for your school to be recognized okay tutor abey las piñas national high school i know I hope the people of Paranaque are watching this. I can see some comments here. Good afternoon, watching from Santo Nino Elementary School, Mary Lou De La Cruz.
Then, from National High School, Santo Nino, Paranaque City. There's also SDO Paranaque. Watching from Paranaque National High School, Maine, Alec Fradezape.
Hi, ma'am. Good afternoon from Las Peñas National High School. Tutor Anne, Senior High School STEM Influence. From Hans. And good afternoon from Las Piñas National High School STEM 11a independence from Frances Elijah.
They are our new students. We haven't met them virtually yet. I will meet them tomorrow. So thank you for saying yes for attending this free online tutorial.
Thank you Tutor Abay for this week, the most essential learning competency that we're going to tackle. So to the students, it depends on how we look at the... It depends on our perspective.
So here, let's open the most essential learning competencies and look at them positively so that it's not too heavy for us to study. In here, number one, we have used properties of matter to identify substances and to separate them. It's easy, right? They'll remember, I'm sure, their lessons when they were in your junior high school. And then, recognize the formulas of common chemical substances.
so marami tayong mga nai-encounter ng mga chemical substances and i'm sure alam nyo ang mga chemical formula next is describe separation techniques for mixtures and compounds so separation techniques na lesson to sa junior high school so magre-requel lang tayo ng mabilis okay so we have prepared here an activity about intensive and extensive property you may also type in you may also play that using this uh link. Pero mamaya na, after this tutorial, let us all together answer this activity. So we have intensive and extensive properties.
We will mention later the definition of intensive and extensive properties. But I want you first to assess your learning. Your memorization in this lesson. What are the properties found on the left side of this presentation?
Let us categorize that and let us put that in its correct property. So, let's start with taste. So, Tutor, I will help you.
Let's look at the answers. Students, tutis kindly type in your answer if taste will fall under intensive property or extensive property. Kindly just type in IP or EP if that is your answer. And also, put LPNHS-SHS. For example, I am also a student from LPNHS.
If your answer is IP, IP LPNHS-SHS so that we can recognize. Last semester, Ang maraming mga students ay from Taboc City National High School. Tingnan po natin this.
From what school naman po ang mas maraming magka-participate. Okay, for the taste, may nag-comment na po ba? Tutor Abay? Sige, wait lang natin sila. Tutor Anne, baka pinag-iisipan pa nila.
Again, IP or EP na lang para mas madali yung inyong time, pag-type ng inyong answers. Taste is about sensation of flavor. Okay, sensation of flavor.
flavor perceived through mouth so also Good afternoon, Tutor Anne. We have one answer here from Hans, LP NHS, Senior High School, IP. I would like to give a shoutout to Sir Jovith Heniebre, Chairman of Program Implementation Committee.
Thank you Sir Jovith for attending our online tutorial. I hope you will be asked about chemistry after this. The pressure is here, sir. May nag-answer na?
Yes, Tutor Anne, most of their answers, kay Fritz Casas, kay Angelica, kay Emmanuel, IP yung sagot nila. Okay, so let us check. Sina Hannah Patricia din, mag-tila yung nag-answer. So let us check if your answer is correct.
Okay, the answer is IP. Let's proceed to the next one. Ayun, napakita ko, Tutor Abe, sorry.
So, this is about extensive... property so let me get a kind of blue you intensive you taste intensive and then you volume I extensive how about hardness so hardness is ability to resist deformation and okay I am hardness where will it fall intensive or extensive IP or EP hardness is it right or EP Let's see the comments. There, Sir Jovi.
Thank you. Thank you. According to Emmanuel, EP.
Okay, said Emmanuel. Emmanuel Aklau, EP. Aklau is the partner. So what else? Right, Christopher, he said IP.
Okay. Aliana Chacon said IP. So let us see.
So someone said IP, someone said EP for Martin. So let us check. Okay for hardness, it is the ability to resist deformation. The answer is IT. It means it talks about the characteristic of that thing.
Next is, oh I saw it again. The next one is melting point. I saw it again.
Melting point is an intensive property. When we say melting point, this happens when the matter or when the object turns from solid to liquid so that is melting point that is an intensive property how about shape our students so back include So, you also write down the shape? I write down the shape and the IP. So far, I have seen schools from Las Inas National High School and also some from Paranaque National High School. Of course.
But kindly share this tutorial so that I can help them in their asynchronous learning. Okay, someone said, Okay, Manuel Aclau, IP for shape. Okay, it said IP for shape.
When you say shape, so will it talk about an intensive property or extensive property? So we'll see. I'll pick the answer.
Shape is extensive. property so you uh nabigyan na kayo ng mga hints may mga properties uh sa intensive property and extensive property ano kaya yung clue natin dito para malaman natin kung intensive ba siya or extensive mamaya we'll give the definition okay next is lumabas ulit so baka kasi medyo matulog ito so mask so tatlo tatlong properties na yan intensive properties uh taste hardness melting point may nanonotice ba kayo and then extensive property volume shape mass so john palang alam niyo na kagad yung agka categorize ng property intensive or extensive the next one is density density Kanina may nabasa akong shape, naitama niya naman EP yung answer niya. Sa shape, nasa shape pa rin sila.
Shape, EP, okay. Okay, density. What about for density kaya?
For density, tingnan natin. Kaya may type in density. Ayan, according to Frances Elijah, density is IP.
From Las Pinas National High School, STEM Independence. We will see if your answer is correct. Baka intay pa tayo ng iba.
The answer? According to Carleen, EP, Las Piñas National High School. Kaya lang hindi ko alam kung ano yung variable na tinutukoy niya. So according to Aliana, density is IP. Aliana Chacon from Las Piñas also.
Let us check if your answer is correct. So density is under IP or intensive property. the next one is luster. Ano ba ibig sabihin ng luster? It is the light reflective property in one word siguro yung pagiging shiny okay so light reflective property yung luster ano kaya siya intensive or extensive so may mga clue na kayo dyan sa mga examples ng property na na-present kayon ano kaya ang luster is it intensive or extensive okay Laster is a light reflective property.
May I answer now, Tutor Abe? Tutor Anne, according to Isaiah Albarina, Laster IP. Laster IP.
Okay, may I... For Rye Christopher, it's EP. Okay, so let's guess. IP or EP, their answers are different. It's okay.
We'll answer it later. We'll summarize it later. Okay, the answer is IP. The last one is about IP.
The next one is, I clicked on it again because we might have time because we have a lot to discuss. This boiling point depends on the type of molecules that make up a liquid. That is the boiling point. It depends on the intermolecular forces of attraction and I discussed the boiling point in Gen Chem 2. It was discussed by the students who are now in grade 12. So now, We will discuss further the boiling point about intermolecular forces of attraction.
So that is an example of intensive property. How about the color? Kindly type in color and then IP or IP. For color, is it IP or IP? The comments are coming in real time in FB Live.
For the meantime, yes, meron na sa color. We have Nuki Havre, IP color, Angelica Gregorio, boiling point is IP, Aliana color IP, color IP for Emmanuel, even for Rai, Frances also. So let us see if your answer is correct. Thank you sa mga nagpa-participate natin mga students.
Color is an intensive... property and lastly length length is an of course intensive length is and Extensive property. Kung mapapansin nyo ang extensive property about volume, shape, mass, length.
So let us sum up that, yung i-describe natin yung intensive, extensive with a few words para matandaan natin ano ba yung intensive, ano ba yung extensive property. So we have sa intensive properties, these are properties that do not depend on the amount of matter. So hindi sila nakadepende sa...
or the amount of a thing. Examples are color, so it's not because it's a lot that its color will be high. So it's not because of its boiling point. The boiling point of water is 100 degrees Celsius.
No matter how much water it is, even if it's just a glass or a drum, its boiling point is 100 degrees Celsius. The density of a glass of water is 1 gram per ml. Even if it's just a drum, it's still 100 degrees Celsius. the density is still 1 gram per ml because it is water. So that is the identity of water.
Next is extensive property. These are properties that do depend on the amount of matter. So it means that it is based on the amount of water. So for example, my hair, the volume of my hair, or the mass of my hair, or the length of my hair, I'm talking about the extensive property of my hair. So, kung color yun, kung brown ang hair ko, that is about intensive.
Kung about its volume, that is about extensive. So, yun ang ating recall for intensive and extensive property. And I know Tutora Bae will help us discuss further or she will discuss further with us the physical and chemical properties.
So, let's hear it from Tutora Bae. Okay. So, thank you, Tutor Anne. So, let's start with the properties of matter first. So when we talk about properties of matter, it's actually a matter that can be formed in solid, liquids, or gases, wherein if we will be observing a certain object, you can discover its various properties.
Chemists classify matter based on its properties, characteristics, and behavior. Some properties can be observed only by experimentation, while others can readily be observed using our own knowledge. I know you will say that our topic is very elementary.
We said that you are very familiar with matter. When we talk about matter, we are dealing with anything that occupies space and has mass. The good thing about chemistry tutors is that we need to give them concepts. Starting from elementary to college, you will use concepts of chemistry.
But today, we will just be focusing with the properties or yung tinatawag nating katangian ng mga bagay-bagay. For example, madali ba siyang ma-dissolve sa water? So kapag ganon, we will be dealing with solubility.
Then you will be asking yourself, madali ba siyang mag-react kapag inagbe siya sa ibang substances? So those are the questions that probably will come into your mind. you are going to answer that by simply observing the experimentation or your observation.
Then, we will also talk about the chemical properties. So, maybe that's the first thing we will do. So, when we talk about chemical properties, these are properties that can only be observed when there is a change in composition of the substances.
So sabi nga natin, nung junior high school kayo na pag-aralan nyo na yan, even when you were in elementary, na pag-aralan nyo na yung chemical change. So sabi nga natin, di ba, pag chemical change, merong new substance na nafo-form. So lagi nyo tatandaan yan, dapat may bagong substance na form para maklassify natin siya as chemical change.
It underwent chemical change. So it is a manifestation na may nabago na sa composition. And also it can be manifested through... biodegradability, reactivity, and combustibility. So, dito sa tatlo na ito, very obvious naman, meron at merong nababago sa composition.
Of course, hindi na natin mababalik yung original substance after the reaction. So, next property is physical property. When we talk about physical properties, these are characteristics of matter that can be observed or measured without changing the composition of the substance. Some examples of physical properties are volume, density, color, melting point, boiling point, etc.
So, earlier, Tutor Anne gave a lot of examples under the physical properties. So, you can use that so that you can be able to visualize what is exactly the meaning of the physical properties. Isa sa mga pag-uusapan natin under physical property is density. The densities of objects are all different. For example, water and alcohol.
Knowing the densities will tell you about the identity of the unknown substance. Minsan kasi magkaparehas ng itsura. The way we look at it, ginamit natin yung mata natin, parehas sila ng itsura.
Come to think of it, hindi lahat ng parehas ng itsura ay parehas ng substance. So we have to go beyond our observation. Pero, class, para sa ating mga tutis, hindi tayo pwedeng basta-basta tumikim ng substances in the laboratory or even touch it.
We are not allowed to taste it. For your safety na rin. So ang pwede natin gamitin ay, kuhani natin yung density ng dalawang substance. Kuhani mo yung density ng water and alcohol.
And then based on the representation here, The density of water is 1 gram per milliliter while alcohol is 0.79 gram per milliliter. So, ibig sabihin same appearance pero different yung composition. Knowing the densities will tell you all about the identity of the unknown substance. Let's talk about the heating process.
So, substances react to heating differently. Tutor, ang new slide natin. para makita rin nila.
Some are heated very quickly and others are slow to heat up. So in the picture you are seeing their device wherein it is being used to measure the temperature of different materials so like concrete and metal. It can also be used to measure the heatness of aluminum and iron. Wherein, as we all know, iron and aluminum can conduct heat well. So that's the reason why we are using those materials in the preparation of pots and pans.
Kaya yung mga kitchen utensils natin usually made of aluminum. So materials that are used in household insulation cannot conduct heat. Kaya naman, kung mapapansin ninyo yung mga bahay na, yung pangkaraniwang bahay na makikita natin dito is out of wood.
kasi hindi ganun kabilis na nag-transfer yung heat sa material na yun. So, it's going to be comfortable for us if you will be using those kind of materials. Nagiging insulation, insulator siya.
Next is, so, tuturan may mga instances na kailangan nila ng exact value ng heating rate. Probably, they can visit the internet, right? They can search heating properties ng bawat material. Because we can't separate it. But on the internet, there are all the various rates of various substances.
Next is solubility. Solubility is the ability of substance to be dissolved in a given solvent. So, as we all know, the different substances have different solubilities.
I will be explaining that to you later on. For example, sugar and dirt have different solubilities in water. So, Teacher Anne, do you remember our experiment in grade 7 with regards to this representation?
Yes, Tutor Abe, the experiment in grade 7. I know that some students might have encountered that activity. You're going to test the solubility of salt and sugar. You're going to compare.
They have different substances but the same amount of water. So two glasses of water. 100 grams of water.
How many grams of salt will be dissolved in that 100 grams of water? How many grams of sugar will be dissolved in 100 grams of water? So it can be compared.
And I know, as I remember, because it's part of my thesis, 36 grams of sodium chloride or salt in each 100 grams of water. More than that 36 grams, it can't dissolve or dissolve. And for the sugar, what you can dissolve is 130 grams of sugar.
More than that 130, you can see the undissolved solutes, undissolved sugars. So I know they still remember their experiment in grade 7. The good thing about our topic, Tutor Anne, is that until the end of chemistry, they will use this. So if we discuss the saturation of solutions, they will recall these concepts.
So that's the reason why. If they remember that until college, I'm sure they will bring their house. So, it is important to know the properties of matter because it can help us identify exactly the unknown substances.
Then, we have another thing to discuss. It is important to know, especially in electrical wirings. There are metals that are good conductors of electricity.
It says in our presentation. Tutor Anne, before I continue, I will just shout out to my students. They are here.
Yes, they are here. So, we have Ken. Maxjo, Benjo, Roland, Mark, Benjo, and Fiona, thank you for watching.
I'm sure they will attend regularly. So let's talk about the electrical property or the electric properties of different substances. So some substances are better conductors of electricity than the others.
Copper wire is a good conductor while rubber and plastics do not conduct easily. Electrical properties of unknown substances can be tested with the proper equipment. So, maybe that's why they noticed that our cords, our wirings, they're wrapped in rubber. So, that's a very basic example for our safety.
We should know that. So, when it's covered, we can't touch that metal. So, the common thing we use here is the tester that's in the picture.
I know you're familiar with that tester, but I feel like Tutor has a good experience here. Oh, what's your problem? Because when I was a kid, I was taught by my brother, he gave me a tester. If I stick it here on my head and it moves, it means I'm smart. And if it doesn't, or the movement is slow, it means I'm weak.
So I was taught by my brother there. Shout out to Raymond Mancilla. Thank you for making me realize how smart it is. But again, that is for electrical properties.
It's not for our intelligence to measure. So that is to measure the electrical properties of different metal objects. Okay.
So at least your curiosity was revealed, but it's not safe, right? I'm not safe. Okay. So let's try to have another property, the magnetic property, so we can finish this.
So I feel that... Kahit simple lang yung explanation natin sa sana na-absorb ng ating mga students, yung paano natin ipapaliwanag in a very simple way. So magnetic properties, these are substances that can be attracted to magnets.
Magnet can be used to pick up a paper clip, but not a wooden match or a plastic button. So may purpose yung magnet, and that is to attract metals which are also highly magnetic. Pero yung mga, hindi lahat, hindi lahat ng metals ay namamagnet.
Mamaya, ime-mention itong magnetic properties sa ways of separating mixtures with Tutor Anne. So, I think, ready na sila, Tutor Anne, for another set of competency. We're done with the properties of matter.
So, para sa next learning competency natin, for this afternoon, may pasasagutan si Tutor Anne. Okay, yes, Tutor Abay. This our...
common chemical substances and their chemical formula so we will just ask our to identify the chemical formula of the given chemical substances but before that don't forget to type in your school for your school to be recognized again they're not in a number no number one at the young answer and then your schools and we will contact the teacher of the school um you are participating in this kind of activity and malay no and if she's available if he's available we can invite her now again type in your answer and your school for number one okay I haven't moved to Colombia yet. For number one, glycerol. I really started with glycerol because it's a common chemical substance.
It's not that common in our daily living. But it's important that we know. Try to guess which of the five chemical formulas is glycerol.
Just eliminate the ones that are like chlorox, salt. so kindly type in your answer number one anong answer nyo and then you type in your school name Okay. Okay.
Okay. Okay. Okay.
Okay. Okay. Okay. Okay. Okay.
Okay. Okay. Okay.
Okay. Okay. Okay.
Okay. Okay. Okay. Okay.
Okay. Okay. Okay.
Okay. Okay. Okay.
Okay. Okay. Okay. Okay. So let's wait for their answers.
As of the moment, they are still in the good afternoon. So let's see what do you think is the answer for number one. Okay so Frances Elijah Letters C.Daw. So let us see if Frances is correct. Same answer with Cassandra.
Yes and Ken Joshua. I feel like they are prepared. This is your student tutor Abate.
Yes. Cassandra, Mark, Benjo, Aliana, Precious, Kim, and Mark. Let us check if your answer is correct.
Irene and Alfredo. Let's see. The formula of glycerol is C3H8O3.
Next. Salt. There is no mistake here.
Yes. Salt. Sodium chloride. Very obvious na sa pangalan sa chemical name niya. What is the chemical formula of salt?
Number two. Number two. Okay.
Please include your school para alam natin kung saan yung maraming nanonood. So, dito may LPNHS, tsaka may PNHS. So, may message na dito. Ayan na. So, number two is E.
Same, according to... Kurt, to Aliana, for Laika, it's B. Charime E., Mac Joven E. Ang hyper nila, ang bilis nilang mag-comment. Okay, Mac Joven, Aliana.
Mac Joven, yes. Kurt Iso, okay, Laika. Let's see if your answer is correct. Okay, the answer is letter E, N-A-C-L. Next, Clorox, okay.
Clorox is used as disinfectant. In disinfectant, pwedeng sodium hypochlorite or pwedeng calcium hypochlorite. So yung Clorox na ito, dito sa sodium hypochlorite, ano kaya ang kanyang chemical formula? Okay. According to Ken Joshua, we have number three, boy.
Okay, Mark Benjo, Hamito. Number three is dog. The other people who are now entering the internet connection, you said, Jo 3D, okay, Drayton 3D, Cassandra is boy, Cherry May boy, Mac Joven boy too. Okay, so someone said, It's like Bosley boy, right?
being b so let us check if your answer is correct okay chlorox or the chemical formula is b sodium hypochlorite and a clo and then for ammonia nitrogen trihydride nitrogen trihydride very obvious for number four kindly type in your answer so with your school sign language one Okay, for ammonia, nitrogen, trihydride. According to Miguel, number four is A, Miguel Taniola. Okay, we have Mac Joven, Iverson, Irene, Cherry May.
James Dizon, Ken Jaiskin, Gerson Deming. I'm sorry, I'm sorry. Mac Joven, so there you go.
So that's A. Most of their answers is A. Okay, so let's see if your answer is correct.
Okay, ammonia, that is NH3. Next, obvious naman na to. So hindi na natin tanungin yun.
Oo, tutor Anne, may sagot na nga sila ngayon sa comments. Ah, talaga ba? Bilis nila.
Oo. For number five. D. O, diba?
So the answer is in baking powder, sodium bicarbonate, that's better. D. Okay, next. Ito po ay... A few chemicals.
Identify the chemical substances that are being described in the statement below. Statements below. Okay, let's see. We will give you the statement and then you will try to identify the chemical substance. Earlier, we had a selection.
Ito, it is an anesthetic for minor surgery and is also known as laughing gas. Okay? Yung mga students natin, magagaling sa pagsusearch ng answer.
So, it's an anesthetic for minor surgery and is also known as laughing gas. May mag-answer na ba dito? Tignan natin.
Kahit isa. They know laughing gas. When I was a kid, I thought if I took that chemical, I would laugh a lot. But no, that is an anesthetic for minor surgery.
It will lessen the pain. According to Arnold Chuteran, it's helium. It's just a bubble.
Arnold Delacruz. Okay. Is there more? Chuterabay? There's no harm in trying naman.
So, sige lang. Helium din kay Nico Rosel. Hydrogen, according to Mark Benjo.
Siguro kasi yung helium pag natin, mamatang-matang sa boses. Okay. We have nitrous oxide from Miguel Calvo Taniola de Ford. Okay, Miguel Calvo, nanalo ka ng one point.
And to Oprah for Brian David. Angelica Iverson Angelica Gregorio Nitrous Oxide Nitrous Oxide or N2O that's also known as Laughing Gas. Next is it is the chemical substance that is used to chlorinate swimming pools So that's the one I mentioned earlier I said earlier that there are two types of this and calcium that's the compound so that compound is the answer to number 2 it's in the previous activity according to arnold de la cruz chlorine okay you make chlorine okay the term that we have here is hypochlorite so when you say then chloride because it's calcium, the solution is a bit white.
So lastly on this part is it is the chemical substance that is used to make cakes and other baked products rise in the oven. It was also asked, it was also in the activity earlier. Okay, it is the chemical substance that is used to make cakes and other baked products rise in the oven. Okay, number three.
So, they might answer the common name. That's okay, right? Yes.
I just found out. My student from Las Penas National High School, Miguel Calvo Taniola, and Angelica Gregorio, she also said, is chlorine. Joseph Natividad Ibanez answered. So, let's not just say Paranaque or Las Penas. Paranaque.
Paranaque. Okay. The answer, someone answered, Mark Benjo Hamito, sodium bicarbonate.
It's Paranaque, I think. Yes, I met him earlier. Okay. The answer is soju by carbonate. Mark Benjohanito.
Baking powder for Alfredo Aguirre. Flour for James Dizon. I will speed up the tutorial because we have another learning competency that we want to tackle.
And I know our students still remember this. We discussed this in their junior high school and we have a few minutes left. So the first separation technique that we're going to discuss is decantation.
It is a process for separating the liquid component of a solid-liquid mixture from the solid by pouring. So we're doing this but we're not familiar with the term decant. So for example, solid and liquid mixture, you let the solid material settle at the bottom and then you will add So that you can separate the liquid from the solid, that is called decantation.
So that should be the proper term. Next is chromatography. When we do face-to-face, we do this activity, remember, in chalk chromatography.
Then when we read our books, the prints are chromatographed. So when you read your modules, you will see that there are some that are separated, there are colors, there is pink that comes out, black. The ink is thick but there are different colors that come out.
Separating components of a mixture that have different adsorptive tendencies on a stationary phase. This separates ink pigments. Try using different markers.
and you will see that it has different components. Next is centrifugation. This centrifugation, we can see it in hospitals, a method of separating molecules having different densities by spinning them. So what's common here is to try to base it on blood.
So you will put a sample of blood there, then you will put the machine under it, and then you will separate it. So that's where the components are tested. If there's something high in your blood or low, it's tested there.
Next is another way of separating the components of a mixture is distillation. This one is about the boiling point. Process of separating components of a mixture based on boiling point. Of course, liquid substances have different boiling points.
We can now do the distillation process. We have this evaporation that involves heating the solution until the solvent evaporates. The seawater will evaporate and the rock salt will also evaporate. This is common in the Paranaque and Las Piñas. This is known as asinan in our area.
Next is filtration. This is very familiar to everyone. It is used to separate insoluble solids from liquids with the use of filter paper. I remember that some students were confused.
What is the name of the solid left on the filter paper? It is called residue. And then the clear liquid that is cast through the filter paper, that is what you call the filtrate.
Okay, next is? Mechanical separation is used to separate the components of a mixture with the use of tools such as forceps or sifter. Just like when you bake, the sizes and other components are separated. As long as you use a tool, that is a mechanical separation. Lastly, we have magnetic separation.
We discussed this earlier when we used magnets. So, this is so that we don't have to pick up the seeds one by one. We can use a magnet and it's easy to collect the seeds and separate them from the plastic material.
So, used to separate a magnetic solid from a heterogeneous mixture. Okay, so we've covered all three learning competencies. For our next week, it's chemical names and formulas. So, I hope... We will see you again next week.
At ang pag-aaralan natin ay Chemical Names and Formulas. More on nomenclature tayo. Okay?
So, yan ang ating lesson for next week. And also, Tutor Abay. Mm-hmm, Tutor Anne.
So, sana marami silang natutunan, no? So, with that, we would like to inform you na aside sa amin, there are also sets of tutors under Team Mahusay who are... preparing for other subjects in science for first semester in senior high school ito ay inihanda at totoong para sa bata para sa bayan.
Muli I am tutor Abe and I am tutor Ann pero bago yan tutor Abe let me promote muna the offering yung mga inooffer para sa first semester para sa senior high school if you need some tutorial about all this wellness coding and robotics Safety and First Aid, Earth and Life Science, and then sa atin, General Chemistry 1, General Biology 1, susunod na, and then Mommy Tech Talks, Level Up. So pwede niyong i-visit yung Facebook page ng DepEd EdTech Unit at maandun yung mga kailangan niyong mapakinggan about your lessons sa senior high school. Hindi lang sa senior high school, elementary, junior, and senior high school. Okay, so once again, join us again next Monday, same time. 4 o'clock to 4.40 p.m.
for another exciting topic in chemistry. Kaya naman, sama-sama natin itulay ang pagkatuto. Itulay ang bayanihan para sa mga batang.
