1. The lesson plan describes a science lesson for 5th grade students about physical and chemical changes in matter. 2. Students are divided into groups to observe and compare physical changes in matches and paper through breaking, burning, and tearing. 3. The teacher then explains that physical changes alter the object's form but not its internal composition, while chemical changes result in a new substance through changes in molecular composition. Examples of each type of change are discussed.

Objective: at the endof the period,the pupilsshouldbe able to: 1. describe changeshappeninginacertainmatter 2. compare the characteristicsof physical change andchemical change 3. classifythe changeshappenedtothe object,if itisphysical orchemical change 4. showwillingnesstohelpeachmembersonassignedgroupactivities II. SubjectMatter: ChangesinMatters Values: Beingobservanttothe changeshappeninginourEnvironment III. Materials: Chart Visual Aids Paraphernalia(variables) - Matches - Papers - Piecesof the matches’part - Burnedmatch - Cut papers - Burnedpapers IV. Procedure: A. Motivation: Teacher’sActivity Pupils’ Activity Good Morning! Please observeyoursurroundingsandany piecesof messyousee putit onthe trash,and alignedyourchairsproperly. VeryGood!You may nowbe seated. Last weekwe discussed all aboutmatter.May I knowwhocan recall what matteris? Good MorningSir! (pickingpiecesof paperoranydirt andaligningthe chairs) (pupilswillbe ontheirseat) Student#1:matteris anythingthathas massand takesup space
- 2. Another? VeryGood Please give them3claps Before we startto our lessontoday,Iwould like togroupyou into two (2).Firstgroup are on my leftside andthe secondgroupwill be onmy rightside.Youmay nowgroup yourselveswhile youare singing“The more we get together...”and simultaneouslymake awide circle onyourgroup’s place. I have here samplesof twoobjectconverted intotwo differentforms. I wouldlike youtoobserve changeshappened by comparingitinterms of size,colorand texture. Understood? In groupone,the task will be Matchesonits original composition,BurnedandBroke into pieces. In grouptwo,will be Papersonitsoriginal composition,BurnedandTear intopieces You may start now! Student#2:Matter is anything,suchasa solid,liquid or gas that has massand occupiesspace. (unitingeverygroupwill singing“The more we get Together”) “The more we gettogether,together,together.The more we get togetherthe happierare we. Andyour friendsare myfriendandmyfriendsare your friends The more we gettogetherthe happierare we.” (Listening) Yes,Sir! (Listening) (StartingtheirworkandsharingIdeas) Answer to the group activity characteristics Group 1 Group 2 Matches Paper Break into pieces Burned Tear into pieces Burned size smallerthan to the original size powderedor transformedinto itssmallestform or it became ashes smallerthanthe normal paper ashes-like size color same color from itsthe original colorblack same as the original colorblack withthe touch of gray texture same as the original rough rougher same as the first objectsmooth easilytear
- 3. Okay,Time isup. Please stopwritingand postall yourwork on the board. Choose two representativestoexplainwhat youhave observed. VeryGood. Please give Group1 an ANGEL CLAP. VeryGoodalso. Give Group 2 an OISHICLAP. (everygroupwill posttheirworksonthe board) Group 1 Rep.: The matchesthat broke intopieceshave smallersize compare to itsoriginal formbutsame color and texture.Onthe otherhand,the burnedmatchesare veryfar fromits characteristicsintermsof size,color and texture fromthe original.Itgetspowdery,color blackand rougher. (Clap) 1 2 3 (Stampyourfeet) 1 2 3 (make a Halo) Angel... Group 2 Rep.: The paperswere cut intopiecesbutalsosame color and texture asthe original.But,onthe burned papersit became ashes.Colorblackandwhenyou holdit,it easilydestroy. (Clap) 1 2 3 (Stampyourfeet) 1 2 3 Oishi... B. Presentation: You all have verygoodanswerand your answersare much closedtoeach otherbut differentvariables. In Group One,Matchesand inGroup Two Paper. A while ago,twoof your classmate defines whatmatter is,and one of themanswerthat matterhas itsstates. Who can give me one state? Another?yes and lastone. Verygood,please give them 4claps (Listening) Student#1:Solid Student#2: Liquid Student#3: Gas Class:4x clap
- 4. Andmattersmay alsochange. Changesinmattermay occur whena force or energyapplied inanobject. For example (getapiece of paper) I will tearthispaperintopieces. What changeddidyounoticed? Verygood.The size,itbecame smallerthan the original AndWhy do youthinkso? Verywell said I tear itwithmy twohands,it will neverbe tearingintopiecesuntil someone or somebodywill doright? How aboutthe lightedmatches,what changeddidyounoticed? Okayanother. How aboutthe color? Verygood,and last VeryGoodpupils. Give yourselvesaYES CLAP. What we didearlier(MatchesandPapers activity) undergochanges, Andmay be classifiedintoPhysical or Chemical change. (listening) Student#1:it became smaller. Student#2:because youexertedforce forittobe transformedinto pieces. Student#1:it became ashes Student#2:the color became black Student#3:became rougherbecause of itssize. (Clap) 1 2 3 (Stampyourfeet) 1 2 3 YES... Physical Change Chemical Change - An objectmaychange inform but not inthe kindof moleculesithas - The moleculesof anobject changedintoanotherkindof molecules and a new substance withnew properties isformed. Examples: logschangedintowoodchips Examples: rust inirons

Justlike the paperI tear intopieces.Onlythe size and shape changedbutnot itsinternal component. Physical Change isalsocalledReversible change where inthe resultingelementcanbe opposite into the objectbefore.Changesthatcanbe reversed. Take a lookat thischange. What state of matterthe ice is? Verygood. Andwe all knowthat when we put the ice intoa hotterplace it melts.Butthe compositionof the ice isthe same as the water,onlythat itchangesit form.Understood? Do youthinkwe bringback the waterintoitsearlier form?How? (Listening) (Listening) Student#1:Solid Class:Yes. Student#1: Yes,we can putit on the colderplace such as refrigerator.
- 6. OkayVeryGood. Andwhenwe say Chemical Change, the internal make-up(molecules) of the objectchanges. Unlike aphysical change,chemical changescannot be reversed.Changesthatcannotbe reversedare calledNon-reversible Change.We cannotbringit back to itsoriginal form. Everyday, we experience chemical changesin manythingsaroundus. How aboutyou. What youhave noticedto the burnedmatches fromactivity. Okay,youmay be seated. Thinkof the drywoodin the fireplace.Whenwe lightthe woodup,it burnsgentlyandaftera while it turnsintoashes.Asit burns,itproducesheat, lightandsmoke whichescapesthroughthe air.The heat,light,fire andsmoke are all good characteristicsof a chemical reaction,whichresult ina completely new matter—ashes. Note that the ashesfromthe burningwoodhave an entirelynewmolecularcomposition.Itcannever be turnedback intowoodagain. Understood? Okayhere are the otherexample of Physical change (Callingthe studenttostandupand answerthe question) Student#1: it became asheswhenlighted,the coloris differenttothe original anditstexture is rougher. (Listening) Class:YesSir. Physical Change SlicedFruit(Papaya) Logs intowoodchips
- 7. Andon the otherhand,the Chemical Changed Chemical Change Who can give me otherexamplesinPhysical Change? VeryGood,Another? Okay,good. How aboutChemical Change. Excellent.Lastone. Wow,veryexcellent. Student#1: blendedfruits Student#2: crumplingpaper. Student#3: spoiledmilk Student#4: digestingfood. C. Application: I have here an activitythatyouwill be answering togetherwithyourgroups. You will goinfrontone byone and give examples on the followingchangeswe tackled.Alternately give example on the Physical ChangeandChemical change. Understood? (Listening) PHYSICAL CHANGE CHEMICAL CHANGE
