Tyala ilethisi emanzini endaweni yomhlaba uze ube nento engaphezu kweprojekthi yebhayoloji. Uba nenkqubo elawulayo encinci ekufuneka umntwana ayigcine iphila. Itanki le-hydroponics libuyisela umsinga wamanani yonke imihla: ukuba amanzi ane-asidi kangakanani, ukuba izondlo zomelele kangakanani, ukuba sele efudumele kangakanani. Ukufunda ukuwafunda loo manani, ukuqaphela xa etshintsha, nokwenza into ngaphambi kokuba isityalo sibandezeleke kukusebenza ngedatha ngeyona ndlela ibonakalayo. Isingqi sokulinganisa-ukuzoba-ukugqiba esingasemva kwetanki sesona singqi sikwinkqubo nganye ezenzekelayo umfundi aza kudibana nayo kamva.

Isingqi sokulinganisa, ukuzoba itshati, nokugqiba

Ixabiso lokufundisa asisiso isityalo. Sisingqi esinyanzeliswa sisityalo. Isensa ithatha ufundo, ufundo lungene kwitshati, itshati ibonise umkhwa, uze umkhwa ubangele isigqibo. Inani elinye lodwa alithethi nto ingako. Iveki yeenkcukacha ze-pH ezizotywe njengomgca ibalisa ibali: izinzile, iyenyuka, okanye iyantengantenga qho xa impompo isebenza.

Ukuze ufumane umgca endaweni yomfanekiso womzuzu omnye, iinkcukacha kufuneka zibhalwe phantsi kangangeentsuku, zingajongwa nje kanye. Ibhodi efana ne-sheenbot∞ inokufunda isensa ye-pH okanye eyobushushu ngexesha elimisiweyo ize igcine amaxabiso, ukuze abafundi babuye bafumane igrafu endaweni yokutshona kwesalathisi kanye. Xa sele bebona imilo yedatha, isayensi iyeka ukuba yinto engabambekiyo.

Imida iguqula iinkcukacha zibe zizigqibo

Ufundo luba luncedo kuphela xa iklasi ivumelana ngokuba yintoni ephakame kakhulu okanye esezantsi kakhulu. Misela umda we-pH. Gqiba ngobushushu bamanzi apho ubushushu behlobo buba yingxaki khona. Khetha amandla ezondlo athetha ukuba mazongezwe, okanye axutywe namanzi. Ngomzuzu ixabiso ligqitha omnye waloo migca, kufuneka kwenzeke into.

Leyo yingqiqo yemiqathango phambi kokuba kubekho mntu ubhala inkqubo: if pH > 6.5 then add corrector. Abafundi abamisela imida yetanki baqhelisela kanye loo ngqiqo iza kuqhuba i-thermostat, isibali-xesha sonkcenkceshelo, okanye i-alam kamva. Itanki lenza nje ukuba iziphumo zibonakale, zicothe ngokwaneleyo ukuze uzibambe.

Ukukhangela iimpazamo kwinkqubo ephilayo

Izityalo zisilela ngeendlela ezohlwaya ukuqashela. Xa igqabi liba mthubi, unobangela unokuba yi-pH, izondlo, ukubola kweengcambu, itanki elifudumalayo kwiDisemba yaseKapa, okanye impompo eme ngokuthe cwaka. Kunqabile ukuba kubekho tyala linye elicacileyo, ngoko abafundi kufuneka bahlule izinto ezitshintshayo enye nganye: jonga into enye, tshintsha into enye, linda, ubone.

Le yingqeqesho enye nokukhangela iimpazamo kwikhowudi. Gcina irekhodi yoko ukutshintshileyo nokuba ukutshintshe nini. Musa ukutshintsha izicwangciso ezintathu ngexesha elinye, kungenjalo awusoze wazi ukuba yeyiphi esebenzileyo. Inkqubo ye-hydroponics ifundisa umonde ngezingqi zempendulo ngendlela inkqubo enomyalezo wempazamo okhawulezayo ingasoze ikwenze ngayo ngokupheleleyo.

Uluhlu lokuqala lwezinto ekufuneka uzijongile kwitanki legumbi lokufundela

• Khetha isityalo esikhawulezayo njengelethisi okanye ibhasili, ukuze iziphumo zibonakale kwikota enye yesikolo.
• Linganisa izinto ezifanayo ngexesha elifanayo yonke imihla, ukuze idatha ikwazi ukuthelekiswa.
• Bhala phantsi iinkcukacha endaweni yokuzijonga nje, ukuze abafundi bafumane igrafu, kungekhona inkumbulo.
• Vumelanani ngemida phambi kokuba niqale, nize nibhale phantsi ukuba kuthetha ntoni ukuphakama kakhulu nokuba sezantsi kakhulu.
• Tshintsha into enye etshintshayo ngexesha xa kukho into engahambanga kakuhle, uze uphawule isiphumo.
• Gcina incwadi yamanqaku esetyenziswa ngabo bonke ukuze iqela elilandelayo lifumane oko eli seliyifundile.

Ingena phi

Akukho nanye kwezi zinto ifuna irobhothi, kodwa zihamba kakuhle nayo. Ukuva kwezixhobo, ukubhalwa phantsi kweenkcukacha nengqiqo yemida zizakhono ezifanayo nezo sele zakhiwa yiklasi yekhowudi neyeerobhothi, yiyo loo nto itanki liyiprojekthi entle yokudibanisa izifundo. Ukuze ubone esi singqi sisebenza neqela, iwokshophu yeholide ngexesha lekhefu lasehlotyeni yindawo elula yokuqala, okanye ungabhukisha iklasi yovavanyo enye uze ubukele ukuba abantwana bakhawuleza kangakanani ukusuka ekufundeni isensa baye ekuphikisaneni ngokuthethwa yigrafu. Ibhayoloji sisibambiso. Ukucinga ngeenkqubo koko kuhlalayo.
