Tshala uletisi emanzini esikhundleni senhlabathi bese uba nento engaphezu kwephrojekthi yebhayoloji. Uba nohlelo oluncane lokulawula umntwana okumele alugcine luphila. Ithangi le-hydroponics libuyisela umfudlana wezinombolo nsuku zonke: ukuthi amanzi ane-asidi kangakanani, ukuthi izakhamzimba zinamandla kangakanani, nokuthi asefudumele kangakanani. Ukufunda ukuwafunda lawo manani, ukubona uma eseshelela, nokuthatha isinyathelo ngaphambi kokuba isitshalo sihlupheke kungulwazi lwedatha ngendlela ephathekayo kunazo zonke. Umjikelezo wokukala–ukudweba ishadi–ukunquma osemuva kwethangi yiwo kanye umjikelezo osemuva kwazo zonke izinhlelo ezizenzakalelayo umfundi azohlangana nazo ngokuhamba kwesikhathi.

Umjikelezo wokukala, ukudweba ishadi nokunquma

Inzuzo yokufundisa akusona isitshalo. Kungumjikelezo isitshalo esiwuphoqayo. Inzwa ithatha isibalo, isibalo sijoyina ishadi, ishadi likhombisa ukuthi izinto ziya ngakuphi, bese lokho okubonakalayo kubanga isinqumo. Inombolo eyodwa yodwa isho okuncane. Isonto lonke lezibalo ze-pH ezidwetshwe njengomugqa lixoxa indaba: linganile, liyakhuphuka, noma liyantengantenga njalo uma iphampu isebenza.

Ukuze uthole umugqa esikhundleni sesithombe sesikhashana, izibalo kumele ziqoshwe izinsuku ngezinsuku, hhayi zibhekwe kanye nje. Ibhodi elifana ne-sheenbot∞ lingafunda inzwa ye-pH noma yezinga lokushisa ngokweshejuli bese ligcina amanani, ukuze abafundi babuyele kugrafu esikhundleni sokubona ukwehla okukodwa kumitha. Uma sebekwazi ukubona umumo wedatha, isayensi iyeka ukuba into engaphatheki.

Imikhawulo iguqula izibalo zibe yizinqumo

Isibalo siba usizo kuphela uma ikilasi livumelana ngokuthi yini ephakeme kakhulu noma ephansi kakhulu. Beka ibhendi ye-pH. Nquma izinga lokushisa kwamanzi lapho ukushisa kwehlobo kuba yinkinga khona. Khetha amandla ezakhamzimba asho ukuthi kufanele ungeze, noma uhlambulule. Ngesikhathi inani lidlula omunye walawo migqa, kumele kwenzeke okuthile.

Lokho kungukucabanga okuncike esimweni ngaphambi kokuba kube khona obhala uhlelo: if pH > 6.5 then add corrector. Abafundi ababeka imikhawulo yethangi bazijwayeza kanye lokho kucabanga okuzoqhuba i-thermostat, isikhathi sokunisela, noma i-alamu ngokuhamba kwesikhathi. Ithangi lenza nje imiphumela ibonakale, futhi ihambe kancane ngokwanele ukuze ibanjwe.

Ukususa amaphutha ohlelweni oluphilayo

Izitshalo zehluleka ngezindlela ezijezisa ukuqagela. Uma iqabunga liphenduka libe liphuzi, imbangela ingaba yi-pH, izakhamzimba, ukubola kwezimpande, ithangi elifudumala ngoZibandlela eKapa, noma iphampu emise buthule. Kuyivelakancane ukuthi kube nembangela eyodwa esobala, ngakho abafundi kumele bahlukanise okuguqukayo: hlola into eyodwa, shintsha into eyodwa, ulinde, ubone.

Lokhu kuwuhlobo lokuziqoqa olufana nokususa amaphutha ekhodini. Gcina irekhodi lalokho okushintshile nokuthi nini. Ungashintshi izilungiselelo ezintathu kanyekanye, ngoba ngeke wazi ukuthi yiliphi elisebenzile. Uhlelo lwe-hydroponics lufundisa ukubekezelela imijikelezo yempendulo ngendlela uhlelo olunomlayezo wephutha osheshayo olungakwazi ukuyifundisa ngokugcwele.

Uhlu lokuqala lokuhlola ithangi lasekilasini

• Khetha isitshalo esikhula ngokushesha njengoletisi noma i-basil, ukuze imiphumela ibonakale phakathi kwethemu eyodwa yesikole.
• Kala izinto ezifanayo ngesikhathi esifanayo nsuku zonke, ukuze idatha ikwazi ukuqhathaniswa.
• Qopha izibalo esikhundleni sokuzibheka nje, ukuze abafundi bathole igrafu, hhayi inkumbulo.
• Vumelanani ngemikhawulo ngaphambi kokuqala, futhi nibhale phansi ukuthi kusho ukuthini ukuba phezulu kakhulu nokuba phansi kakhulu.
• Shintsha okukodwa okuguqukayo ngesikhathi uma kukhona okungahambi kahle, bese uqopha umphumela.
• Gcina incwadi yokubhalela eyabelwanayo ukuze iqembu elilandelayo lithole lokho leli eselikufundile.

Lapho kungena khona

Akukho kulokhu okudinga irobhothi, kodwa kuhambisana kahle nalo. Ukuzwa, ukuqopha nokucabanga ngemikhawulo yiwona makhono afanayo asevele akhiwa yikilasi lokubhala ikhodi ne-robotics, yingakho ithangi liyiphrojekthi enhle kangaka exuba izifundo. Ukuze ubone lo mjikelezo usebenza neqembu, iworkshop yamaholide ekhefini lasehlobo iyindawo elula yokuqala, noma ungabhukha ikilasi lokuzama elilodwa ubuke ukuthi izingane zisuka ngokushesha kangakanani ekufundeni inzwa ziye ekuphikisaneni ngokuthi igrafu isho ukuthini. Ibhayoloji yisidonsi. Ukucabanga ngezinhlelo yikho okusalayo.
