Ehlobo futhi, ikakhulukazi ngamaholide afana noKhisimuzi noma iPhasika, abazali nezingane banethuba lokuchitha isikhathi esiseqophelweni eliphezulu ndawonye. Kungalezi zikhathi lapho siqaphela khona ngokwengeziwe ubude bosuku nezinto ezihlukahlukene ezingajatshulelwa, njengokuya echibini, ukudlala ngezinto zikagesi, noma ukubukela ithelevishini. Nokho, kubalulekile ngokufanayo ukwethula isayensi njengendlela yokuzijabulisa. Izingane ngokwemvelo zinomqondo wososayensi, njalo zakha imibono eqanjiwe futhi zihlola ngokuzama ngamaphutha. Ngakho-ke, ayikho indlela engcono yokuzibandakanya nokubakhuthaza ngaphandle kokubakhuthaza ekuhloleni kwabo umhlaba, imvelo, kanye nemithetho ewulawulayo.
Ngakho-ke, sizokukhombisa okuhle kakhulu Izivivinyo zesayensi ezi-5 zezingane.
Kungani wenze izivivinyo zesayensi eziyisisekelo ezilungele izingane
Ucwaningo olusha lwembule ukuthi izingane zinengqondo yesayensi futhi zibhekana nezinkinga nophenyo ngendlela efanayo nabacwaningi. Inqubo yokwenza ama-hypotheses, ukwenza izivivinyo, nokuqinisekisa imiphumela ngokusebenzisa ukuhlola namaphutha kubonisa indlela efanayo esetshenziswa ososayensi ekufuneni kwabo ulwazi. Yileli lukuluku nesifiso esizalwa nalo sokuhlola umhlaba okwenza ukuhlola kukhange ikakhulukazi ezinganeni.
Ukwenza izivivinyo ekhaya akudingi izisetshenziswa ezikhethekile noma izinto ezingavamile. Eqinisweni, izinto zansuku zonke zingasetshenziswa ukwenza izivivinyo ezizomangaza futhi zibandakanye izingane, zikhuthaze ukukhula kwazo kwengqondo futhi zivuse ilukuluku elijulile lokuthola ulwazi olusha.
Izivivinyo zesayensi ezi-5 ezihamba phambili zezingane
Insipho yokuxosha amagciwane
Abazali bawazi kahle umkhuba wezingane wokukhathala ngendlela emangalisayo uma kuziwa endabeni yokugeza izandla. Uhlu lwezaba zokugwema lo msebenzi obalulekile lubonakala lukhula ngokungapheli: indlala, ukukhathala, ukukhathala, nokunye. Nokho, kubalulekile ukuthi izingane ziwuqonde ukubaluleka okukhulu kokusebenzisa insipho njengekhambi eliqinisekile lokuvimbela izifo, izifo kanye nokuba khona okwesabekayo kwamagciwane.
Ngokubeka isitsha esinamanzi eduze "negciwane" (njengopelepele ophansi), into ethakazelisayo ingabonwa. Ngokungezwa kwensipho, igciwane liyanyamalala ngokushesha, ngokubonakala ngomlingo. Lo mbukiso awugcini nje ngokujabulisa izingane, kodwa futhi uzifundisa isifundo esibalulekile.
I-volcano ekuqhumeni okuphelele
Umkhakha wamakhemikhali unikeza amathuba amaningi okwenza izivivinyo ngokunethezeka kwekhaya lomuntu, njengoba ukusabela kwezinto ngokuvamile kuveza imiphumela engalindelekile. Isibonelo esihle kakhulu salesi senzakalo singabonakala ngokuhlanganisa izinto ezimbili ezitholakala kalula ekhishini: i-baking soda noviniga.
Ngokulandela lezi zinyathelo, ungakha umuzwa ongenakulibaleka ngokwakha imodeli yentaba-mlilo eqhumayo. Umphumela uba igwebu elikhula ngokushesha ngosayizi, okuyinto ibangela ukuthi ikhuphuke phakathi kwesitsha futhi, kwezinye izimo, ichichime futhi ichitheke. Le nqubo iveza umphumela ophawulekayo, odonsa ukunaka kwalabo abayibonayo.
Ukwakha isakhiwo esifana nentaba-mlilo, sebenzisa ibhodlela lepulasitiki bese ulimboza ngesihlabathi, ubumba, nanoma iyiphi enye into ezolinikeza ukuma kwentaba, uqiniseke ukuthi ukuvuleka kwebhodlela kumelela umgodi.
Izipuni ezimbili zesoda yokubhaka zengezwa ngaphakathi kwesitsha, kanye nenani elifanayo lensipho ewuketshezi ukuze kuthuthukiswe ukuminyana kanye nevolumu yomphumela wokugcina. Ngaphandle kwalokho, Isipuni sombala wokudla obomvu sifakiwe. Isinyathelo esisodwa esisele ukuthululela ngokucophelela ingxenye yengilazi yeviniga esitsheni bese ulinda ngesineke ukusabela.
Esibonisini esikhumbuza ukuqhuma kwentaba-mlilo, igwebu elibomvu kancane lizokhuphuka futhi lichitheke phezu komphetho we-crater. Lesi simo sibonisa igagasi elingavimbeki lodaka lwentaba-mlilo, okwenza omunye wemibukiso emangalisayo kakhulu endalweni.
Ibhaluni elivuthela ngaphandle komoya
Lokhu kuhlola kunezimpande zako ezimisweni zamakhemikhali. Nazi izinqubo ezilandelanayo:
Ukuze uqale, thatha ibhodlela elingenalutho bese uthela uviniga kulo kuze kube yilapho igcwele ingxenye yesithathu. Bese, thatha ibhaluni ubeke ifaneli kulo, uqiniseke ukuthi akukho imvubelo engena ebhodleleni. Beka kahle umlomo webhaluni phezu komlomo webhodlela, uvumele ibhaluni ukuba lilenga eceleni.
Ngemva kokuqeda lo msebenzi, ibhaluni liyaphakama, okwenza imvubelo yehlele ebhodleleni. Ngokushesha amabhamuza aqala ukwakheka futhi kancane kancane ibhaluni liqala ukwanda. Ibhaluni liyakhukhumala ngenxa yokusabela kwamakhemikhali okwenzeka phakathi kukaviniga nemvubelo, okuyinto kubangela ukukhululwa kwe-CO2. Lokhu kusabela kuyimbangela yokwenyuka kwamandla emali kwebhaluni.
Uhlamvu lwemali olunyamalalayo
Lokhu kuhlolwa kungahlukaniswa njengokukhohlisayo, ngezimiso zakhona eziyisisekelo ezisekelwe endaweni yefiziksi kunekhemistri. Izinyathelo zokudala kabusha le nkohliso zilula ngokuphawulekayo.
Etafuleni kukhona uhlamvu lwemali futhi phezu kwalo kunengilazi ekhanyayo nomlomo ubheke phezulu. Ukufihla uhlamvu lwemali ekubukeni okuqondile, ipuleti kufanele libekwe ngokucophelela phezu kwengilazi, okuvumela kuphela izindonga zengilazi ukuveza ubukhona bemali.
Uma ingane isibonile ukubonakala kohlamvu lwemali ezindongeni zengilazi, ipuleti liyasuswa futhi amanzi athululwe ngokucophelela engilazini, ayigcwalise cishe izingxenye ezintathu kwezine. Khona-ke ipuleti libekwa phezulu, njengangaphambili.
Iqiniso liwukuthi ayinyamalali empeleni, kodwa kunalokho ingabonakali ngenqubo ebizwa ngokuthi i-refraction. I-refraction Kwenzeka lapho ukukhanya kushintsha indlela yakho lapho kudlula kwenye indawo ngaphandle komoya. Ngakho-ke uma ubona uhlamvu lwemali olubonakala lunyamalala ngaphansi kwengilazi, akuwona umlingo, kodwa kunalokho kuyisimo sokubona.
Amanzi angachithi
Ukuze uqedele lesi sivivinyo, thatha ingilazi bese uyigcwalisa ngamanzi phezulu. Okulandelayo, beka izinto ezilula, ezibushelelezi njengekhadibhodi noma igwebu emlonyeni wengilazi. Vikela ikhadibhodi endaweni ngeminwe yakho noma ngerula. Okulandelayo, vula ngokucophelela ingilazi, uqiniseke ukuthi umlomo nekhadibhodi kubheke phansi. Ekugcineni, khulula amakhadibhodi futhi ubone imiphumela.
Kwenzekani? Ikhadibhodi lihlala lisendaweni, linamathele emaphethelweni engilazi. Ngokumelene nazo zonke izingqinamba, amanzi awachichima. Lesi simo sibangelwa ukuthi uma ingilazi isigcwele amanzi futhi ivalwe ngesivalo, asikho isikhala esisele somoya. Ngenxa yalokho, kwakhiwa i-vacuum eyenza ikhadibhodi linamathele.
