Ukuhlolwa kwamakhemikhali kwabantwana ekhaya
Ngisho enkulisa izingane zingaba nesithakazelo emisebenzini enjabulo enjalo. Ungakhohlwa ukuthi ukubonisa okuhlangenwe nakho okujabulisayo ekhemistry yabantwana, kufanele uqaphele kakhulu futhi ugcine izinyathelo zokuphepha eziqinile. Nakuba izinto ezisetshenzisiwe ngeke zidale umonakalo omkhulu kubahlanganyeli benkambiso, kusukela ebantwaneni abancane kufanele batshelwe ukuthi baziphathe kanjani ezifundweni ezinjalo. Ungadlulisela inqubo yonke emgwaqweni noma ekhishini, kodwa ezindaweni zokuhlala kungcono ukungalingi.
Ukuhlola nge-ice eyomile kubantwana
I-carbon dioxide, noma njengoba kuthiwa yiqhwa elomile, lisetshenziselwa ukuphuza iziphuzo kanye ne-ayisikhilimu kuphela, kodwa futhi nokuhlolwa kwezesayensi nabantu abanokuzibuza. Lawa makristalu aqinile, okudingeka adluliswe kahle futhi agcinwe ezitsheni ezikhethekile, angathengwa ezitolo ezikhethekile. Into ejwayele ukusetshenziselwa ukuhlolwa kwezingane ekhaya.
- Ukuqamba okulula kakhulu ngeqhwa elomile ukuwuphonsa emgodini ngamanzi apholile noma ashisayo. Kulesi simo, lo mzimba uzoba yi-gaseous futhi kuphakame izinga lokushisa kwamanzi, okunamandla ukuphendula okubonakalayo.
- Okuhlangenwe nakho okuhle kakhulu kwezingane ekhaya kuzoba amakilasi aphephile. Uma ungena emanzini ngeqhwa umsizi omncane wezitsha, khona-ke ukhula isikhwama esimhlophe semibhobho, engathathwa.
Ucwaningo nge-starch yezingane
Ungathukutheli uma ungenawo amabhlokhi e-ice esandleni, ngoba ungasebenzisa ngokunenzuzo ukuthi yini ekhomishini yasekhishini yileyo naleyo nkosikazi. Isibonelo, ukuhlolwa okujabulisayo kwezingane ekhaya kungenziwa ngokusebenzisa isitashi sezambane:
- Into elula kakhulu engenziwa nge-starch ukuyihlaba nge-iodine. Ukuze wenze lokhu, hlaziya isitashi emanzini bese ugibela kuwo nge-pipette ye-antiseptic. I-liquid iyashintsha blue.
- Okuhlangenwe nakho kwezingane ekhaya akuvumeli kuphela izingane ezithakazelisayo, kepha futhi ukugcwalisa imali yengcebo yabo. Ukuze wenze lokhu, udinga ukunquma ama-amazambane kanye nekhukhamba. Phakathi naphakathi kwezicucu kudingeka udonsa iodine. Kulesi simo, amazambane aphendukile okwesibhakabhaka, futhi ikhukhamba iyoba ne-speck ensundu ngenxa yokungabi khona kwesitashi kuyo.
Uhlola ubisi lwezingane
Kungenzeka yini ukusebenzisa ubisi lwezinkomo ezilula ngandlela-thile ngendlela ehlukile, hhayi ngenhloso ehlosiwe? Ngokwemvelo, yebo, futhi ukuhlolwa okunjalo kuyoba mnandi kakhulu izingane ezifunda esikoleni:
- Ukuhlola ubisi ekhaya kulula, kepha akuzona okungaqondakali. Induku eqondile idonswa ubisi futhi umyalezo oyimfihlo ubhaliwe. Ngemuva kokumiswa kumele kube ne-ironed ukwenza izinhlamvu.
- Manje udinga amade kanye nesepha elimanzi. Esigumbini sobisi uthele amaconsi ambalwa amapende, futhi phakathi nendawo ufake idayi nge swab ikotini efakwe ku-detergent. Kuvela amabala e-Iridescent ngenxa yokuthi amakhemikhali awakhipha amafutha avela wona, futhi upende lubonisa ngokubonakalayo.
Ukuhlolwa okwenyama kwezingane ekhaya
Akukhona nje ukuthi imakhemikhali ingaba nesithakazelo ezinganeni. I-Boring physics ingaba "yavuselelwa" futhi ukuhlolwa okuthakazelisayo kwezingane ekhaya nakho kuzozuza. Konke okwenziwe yizinyane, kepha akukwazi ukubona ngamehlo akhe, kungabonwa ngokusebenza ngosizo lwezivivinyo ezilula nezithakazelisayo. Njengomakhemikhali, ukuphepha kwezingane kufanele kulawulwe ngabantu abadala.
Ukuhlolwa ngomoya ezinganeni
Kukhona ukuhlolwa okuhlukahlukene ongaqonda ukuthi umoya ongabonakali uthinta kanjani izinto ezizungezile:
- Uma uthatha ama-lemons amabili, elinye lalo lihlanjululwa, bese lifaka kokubili emanzini, khona-ke "u-ze" uzoshaywa ngokushesha. Lowo ohlala "egqoke" uzohlala ebusweni ngenxa yemoya, efana nama-bubbles amancane, atholakala ngobuningi esikhumbeni sesithelo.
- Ukuhlolwa okuthakazelisayo nomoya wezingane kufanele kuphephe, njengaleyo kuphela ibhola kanye nebhola kuphela elisetshenziswayo. Ku-container epulasitiki elingenalutho, faka ibhola uphinde uwehlise phansi emanzini afudumele . Lapho umoya ebhodleleni uvutha, umoya uzothuthuka, futhi ibhaluni lishaya.
Ukuhlolwa ngomsindo wezingane
Wonke umuntu uzwa umsindo womoya, kodwa akekho ongakwazi ukukubona, ngoba umsindo awubonakali. Kodwa kukhona ukuhlolwa okuthakazelisayo kwezingane ezizokuvumela ukuthi uzame nazo futhi ufunde izinto eziningi ezintsha. Ungabenza bobabili nezingane ezivela enkulisa, kanye nabafundi bamaqembu aphezulu nabafundi abancane. Ngenxa yalokhu, akukho imishini ekhethekile edingekayo, ngoba konke kuyadingeka kuyo yonke indlu:
- Umsindo omuhle ungatholakala ngosizo lwezibuko ezivamile. Udinga ukuthatha ubujamo obukhulu nobukhulu bese ugcwalisa ngamanzi. Khona-ke ngomunwe omanzi udinga ukushayela eceleni komlenze uthatha imisindo ehlukene.
- Okuhlangenwe nakho kwezingane ekhaya - kulula. Udinga ukuthatha indebe yepulasitiki bese uyinquma ngesigamu. Ngemuva kokuthi ifakwe ku-detergent. Khona-ke indandatho kufanele ifakwe kukholomu yomculo. Uma umculo uthule - ifilimu izodlidliza ngokungafani, futhi nge-bass sound - puff.
Ukuhlola ngamagonti wezingane
I-polarity ingumqondo ongaziwa ngokuphelele ingane. Kodwa uma sibonisa ngokusemthethweni ukuthi izenzo ezithinta futhi ezithintekayo, mhlawumbe, abazali bazoba nesithakazelo kakhulu emntwaneni wabo ukuthi i-physicist eyaziwa kakhulu izokhula kuyo. Ukuhlolwa okunjalo okumangalisayo kwezingane kungasetshenziswa njengezifundo ezengeziwe:
- Etafuleni udinga ukuthululela okuncane kwezinhlamvu ezincane noma izikhonkwane, futhi ufake i-magnet enamandla ngaphansi kwetafula. Ukuguqula, ukuqoshwa kuqala "ukudansa".
- Uma sithatha amakhomitha amabili futhi sibasondeza ndawonye, bazokhangwa uma kunezimpawu ezihlukahlukene, futhi uma zifana, zizophikiswa.
Okuhlangenwe nakho ngogesi kubantwana
Umzali ngamunye utshela ingane yakhe ngokuphatha kahle ugesi. Kodwa uma kungenjalo i-volts engu-220, ukuhlolwa okunjalo ngegesi e-static yabantwana akusizi ngalutho futhi kuyasiza ekuthuthukiseni:
- Ukuthatha i-balloon ehlongozwayo kufanele ihlutswe nge-woolen mitten, ikunikeze imali enhle. Ekhokhiswa ngale ndlela, angakwazi ukudweba kuye konke okunezindleko ezimbi - izinwele, imbewu ye-poppy nezinto.
- Izingane ezincane ziyoba nesithakazelo sokubona izidakamizwa zokudansa. Ukuze wenze lokhu, unqume izibalo ezincane zephepha bese uzibeka noma iyiphi indawo. Ngemuva kokusula umbusi wepulasitiki noma ikhekhe ngendwangu yeboya, kufanele uyilahle phansi. Ukugaya amagesi, baqala ukuzungeza emdanso.
