Njengoko uyazi, abantwana banomdla ongapheliyo wokufuna ukwazi. Umnqweno wabo wokufunda iimfihlelo zehlabathi elijikelezileyo uvela kwiindawo eziya kwiinkcukacha ezincinci, ezingenakucingwa ngeso iso. Ngoko ke ngokukhawuleza abazali abaninzi banombuzo othi: "Uninzi kangakanani i-microscope yengane yesikolo kunye nendlela yokuyikhetha?". Yiyiphi i-microscope yokukhetha umntwana wesikolo, kwaye siya kuqonda inqaku lethu.
I-microscope yesikolo: iimpawu zokukhetha
Ukuqala ngokukhetha i-microscope kubantwana besikolo, abazali baya kuqala kwisigqibo sokuba yeyiphi idivaysi engonakaliyo eya kusetyenziswa. Kule nto iklasi yecebo kwaye, ngenxa yoko, iindleko zalo ziya kuxhomekeka. Ukuba ngumbuzo wokuqala komntwana kunye ne-microcosm, ngoko kunokwenzeka ukuba ukhethe okubizwa ngokuba yi-microscopes yabantwana, ezinokubakho ubuncinci bezinto ezintle, kodwa nazo zime kancane. Ukuba i-microscope iyimfuneko yokuqeqesha, ngoko ke kukufanelekile ukuthenga isikolo semfundo (microscope). Iimakroscopes zesikolo zinokwenyuka ukuya kuma-650x. Eyona nto ikhethiweyo phakathi kwezinto ezincinci zezikolo zilandelayo:
- stereomicroscopes;
- microscopes yezilwanyana eziphilayo.
Ngokuchanekileyo phakathi kwezi zimbini iintlobo zezinto ezincinci ezinokuthi zikhethwa xa kuthengwa i-microscope yesikolo esikolweni. Ziziphi ezahlukeneyo? Umahluko phakathi kwezi zixhobo, ngokuyinhloko kwinto yokufunda. I-stereomicroscopes zenzelwe ukufundisisa izinto ezininzi, ezinjengeenambuzane. Banika ukwanda okuncinci, kodwa abanalo umthwalo wemithwalo, kuba umntwana ubakhangele ngamehlo amabini kwangoko. Ukongeza, i-binocular stereomicroscopes yenza ukuba ukwazi ukufumana umfanekiso wesithathu. I-microscopes microscopes ye-biological ine-magnification enkulu, ngoko ke vumela ukuqwalasela izinto ezincinci: iinwele zezilwanyana, iiseli zezityalo, amacandelo amancinci amathishini ahlukeneyo. Kodwa kule meko, i-microscopes yamanye amazwe inika umthwalo omkhulu wemboniso kwaye kunzima ukusebenza, kuba umntwana wesikolo ngokwakhe uya kufuneka alungiselele iisampula zokufunda: ukwenza iinqununu, ukucaza nokumisa iziyobisi, njl njl.
Xa ukhetha umzekelo we-microscope yesikolo, akunakulungele ukubeka ingqalelo ekukholeni kwayo. Ngokuqhelekileyo zonke i-microscopes zanamhlanje zixhotywe ngokukhanyisa okwakhiwe, okuvumela ukuba uhlolisise into yokufunda.
I-microscope yesikolo yedijithali
Olunye uhlobo lwama-microscopes esikolweni ngamakroscopes edijithali. Isixhobo esibi kakhulu, kodwa sinokubaninzi. Okokuqala, i-microscope yesikolo yedijithali ikuvumela ukuba ubonise umfanekiso kwi-monitor monitor. Ngaloo ndlela, umntwana akakwazi nje ukufumana umfanekiso owandisiweyo wento enomdla ngaye ngoncedo lwe-microscope, kodwa ulondoloze umfanekiso obangela ukuba uphinde ufunde okanye uhlele. Oku kukuvumela ukuba ulandele utshintsho olwenzekayo nento yokuqwalasela kwizinto ezinamandla. Okwesibini, i-microscope yedijithali isebenzayo - isenokukhishwa kalula kwi-stand, ihambele ukusuka kwindawo eya endaweni, ngaloo ndlela ifumana umfanekiso ophakanyisiweyo wento ethile kwigumbi. Ngakolunye uhlangothi, oku
Ingakanani ixabiso le-microscope kumfundi?
Ngokuxhomekeke kwimodeli ekhethiweyo, ukuthengwa kwe-microscope yesikolo kuya kubahlawula abazali kwisixa sama-40 ukuya ku-500 iindidi eziqhelekileyo.
Enyanisweni, i-microscope ayifakiwe kuluhlu lokuthenga okunyanzelekileyo kwisikolo , kunye neencwadana, amatyala epenseli kunye nekhefu, kodwa ukufumana kwayo kuya kumnceda umntwana ekuphuhlisweni kwayo yonke.
