Ngexesha lasehlotyeni kwaye, ngakumbi ngeeholide ezifana neKrisimesi okanye i-Ista, abazali kunye nabantwana banethuba lokuchitha ixesha elisemgangathweni kunye. Kula maxesha apho siye sibuqonde ngakumbi ubude bemini nezinto ezahlukahlukeneyo ezinokunanditshwa, njengokuya equleni, ukudlala ngezixhobo ze-elektroniki, okanye ukubukela umabonwakude. Nangona kunjalo, kubalulekile ukwazisa isayensi njengendlela yokuzonwabisa. Abantwana ngokwendalo banengqondo yezazinzulu, rhoqo bequlunqa iingqikelelo kunye nokulinga ngolingo nangempazamo. Ke ngoko, akukho ndlela ingcono yokuzibandakanya nokubakhuthaza ngaphandle kokubakhuthaza ekuphononongeni kwabo umhlaba, indalo, kunye nemithetho elawulayo.
Ke ngoko, siza kukubonisa okona kulungileyo Iimvavanyo ezi-5 zesayensi zabantwana.
Kutheni ukwenza imifuniselo esisiseko yesayensi elungele abantwana
Uphando olutsha lubonise ukuba abantwana banengqondo yenzululwazi kwaye bajongana neengxaki kunye nophando ngendlela efanayo nabaphandi. Inkqubo yokuqulunqa iingcamango, ukuqhuba imifuniselo, kunye nokuqinisekisa iziphumo ngolingo nangempazamo ibonisa indlela efanayo esetyenziswa zizazinzulu kukhangelo lwazo lolwazi. Ngulo mdla wendalo kunye nomnqweno wokuphonononga umhlaba owenza imifuniselo ibe nomtsalane ngakumbi ebantwaneni.
Ukuqhuba iimvavanyo ekhaya akufuni naziphi na izixhobo ezikhethekileyo okanye izinto ezinqabileyo. Ngapha koko, izinto zemihla ngemihla zingasetyenziselwa ukwenza iimvavanyo eziya kumangalisa kwaye zibandakanye abantwana, zivuselele ukukhula kwabo kwengqondo kwaye zivuse umdla onzulu wokufumana ulwazi olutsha.
Imifuniselo emi-5 egqwesileyo yezenzululwazi yabantwana
Isepha yokugxotha iintsholongwane
Abazali balwazi kakuhle utyekelo lwabantwana lokuba batyhafe ngendlela emangalisayo xa kuthethwa ngokuhlamba izandla. Uluhlu lwezizathu zokuthintela lo msebenzi uyimfuneko lubonakala lukhula ngokungapheliyo: indlala, ukudinwa, ukudinwa, kunye nokunye. Nangona kunjalo, kubalulekile ukuba abantwana baqonde Ukubaluleka okukhulu kokusebenzisa isepha njengesisombululo esiqinisekileyo sokuthintela izifo, usulelo kunye nobukho obubi beentsholongwane.
Ngokubeka isitya esinamanzi ecaleni "kwentsholongwane" (efana nepepper yomhlaba), into ekhangayo inokubonwa. Ngokudibanisa isepha, intsholongwane ikhawuleza iphele, ibonakala ngomlingo. Lo mboniso awupheleli nje ekonwabisa abantwana, kodwa ubafundisa isifundo esixabisekileyo.
I-volcano ngokugqabhuka ngokupheleleyo
Inkalo yekhemistri inika amathuba amaninzi okwenza imifuniselo kubutofotofo bekhaya lomntu, njengoko ukusabela kwezinto kudla ngokuvelisa iziphumo ezingalindelekanga. Umzekelo ogqwesileyo wale nto unokubonwa ngokudibanisa izinto ezimbini ezifumaneka lula ekhitshini: i-baking soda kunye neviniga.
Ngokulandela la manyathelo, unokwenza amava angenakulibaleka ngokwakha imodeli yentaba-mlilo eqhumayo. Isiphumo i-foam ekhula ngokukhawuleza ngobukhulu, leyo ibangela ukuba inyuke ngaphakathi kwesikhongozeli kwaye, kwezinye iimeko, iphuphume kwaye ichitheke. Le nkqubo ivelisa umphumo ophawulekayo, othimba ingqalelo yabo bayibonayo.
Ukwenza isakhiwo esifana nentaba-mlilo, sebenzisa ibhotile yeplastiki kwaye uyigqume ngesanti, udongwe, okanye nayiphi na enye into eya kuthi inike ukumila kwentaba, uqinisekise ukuba ukuvuleka kwebhotile kumela i-crater.
Iipuniponi ezimbini zesoda yokubhaka zongezwa ngaphakathi kwisitya, kunye nomthamo ofanayo wesepha engamanzi ukunyusa ubuninzi kunye nomthamo wesiphumo sokugqibela. Ngaphandle koko, I-tablespoon yombala obomvu wokutya ifakiwe. Isinyathelo esisodwa esisele kukuthululela ngokucophelela isiqingatha seglasi yeviniga kwisitya kwaye ulinde ngomonde ukuphendula.
Kumboniso osikhumbuza ngogqabhuko-dubulo lwentaba-mlilo, igwebu elibomvu krwe liya kunyuka ngokuthe chu kwaye lichitheke phezu komphetho wecrater. Esi siganeko sibonisa igagasi elingenakunqandeka lodaka lwentaba-mlilo, ludala omnye weyona miboniso imangalisayo kwindalo.
Ibhaluni evuthela ngaphandle komoya
Olu lingelo luneengcambu zalo kwimigaqo yekhemistri. Nazi iinkqubo ezilandelelanayo:
Ukuqala, thabatha ibhotile engenanto kwaye uthele iviniga kuyo de ibe isithathu kwisithathu. Emva koko, thatha ibhaluni kwaye ubeke ifaneli kuyo, uqinisekise ukuba akukho gwele lingena ebhotileni. Ngononophelo beka umlomo webhaluni phezu komlomo webhotile, uvumele ibhaluni ukuba ijinga ecaleni.
Emva kokugqiba lo msebenzi, ibhaluni iphakama, ibangela ukuba imvubelo yehle kwibhotile. Ngephanyazo amaqamza aqalisa ukumila kwaye kancinci kancinci ibhaluni iqalisa ukwanda. Ibhaluni ivuthela ngenxa yokusabela kweekhemikhali okwenzeka phakathi kweviniga kunye negwele, leyo ibangela ukukhutshwa kweCO2. Oku kusabela sisizathu sokunyuka kwamaxabiso ebhaluni.
Ingqekembe enyamalalayo
Olu vavanyo lunokuthi luhlelwe njenge-optical illusion, kunye nemigaqo yalo esisiseko esekelwe kummandla we-physics kune-chemistry. Amanyathelo okuphinda wenze lo mbono alula ngokumangalisayo.
Etafileni kukho ingqekembe kwaye phezu kwayo kukho iglasi yeglasi ecacileyo nomlomo ujonge phezulu. Ukufihla ingqekembe ekujongeni ngokuthe ngqo, ipleyiti kufuneka ibekwe ngononophelo phezu kweglasi, ukuvumela kuphela iindonga zeglasi ukuba zibonakalise ubukho bengqekembe.
Emva kokuba umntwana ebone ukubonakala kwengqekembe ngeendonga zeglasi, ipleyiti iyasuswa kwaye amanzi agalelwe ngokucophelela kwiglasi, azalise malunga neekota ezintathu. Emva koko iplate ibekwe phezulu, njengangaphambili.
Inyaniso yeyokuba ayinyamalali ngokwenyani, kodwa ingabonakali ngenkqubo ebizwa ngokuba yi-refraction. Ukuchaswa Kwenzeka xa ukukhanya kutshintsha indlela yako xa udlula kwindawo engeyiyo umoya. Ke xa ubona ingqekembe yemali ebonakala ngathi iyanyamalala phantsi kweglasi, ayingomlingo, kodwa yinto ebonakalayo.
Amanzi angachithi
Ukugqiba olu vavanyo, thatha iglasi kwaye uyigcwalise phezulu ngamanzi. Emva koko, beka izinto ezilula, ezigudileyo ezifana nekhadibhodi okanye igwebu phezu komlomo weglasi. Khusela ikhadibhodi kwindawo yakho ngeminwe yakho okanye irula. Emva koko, vula ngokucophelela iglasi, uqinisekise ukuba umlomo kunye nekhadibhodi zijonge phantsi. Ekugqibeleni, khulula ikhadibhodi kwaye ubone iziphumo.
Kwenzekani? Ikhadibhodi ihlala kwindawo, ifakwe kumda weglasi. Ngokuchasene nazo zonke iingxaki, amanzi awaphumi. Lo mcimbi uvela kwinto yokuba xa iglasi izaliswe ngamanzi kwaye ivalwe ngesiciko, akukho ndawo ishiywe emoyeni. Ngenxa yoko, kwenziwa ivacuum eyenza ukuba ikhadibhodi ibambelele.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga neyona mifuniselo mi-5 igqwesileyo yezenzululwazi yabantwana.
