Njengoba wazi, izingane zinezifiso ezingapheli. Isifiso sabo sokufunda izimfihlakalo zezwe elizungezile livela esikhaleni sithumela kumininingwane encane kunazo zonke, ezingenakucatshangwa ngamehlo. Ngakho-ke abazali abaningi banombuzo othi: "Kungakanani inani lezingane ezincane elibiza ngayo nokuthi lingayikhetha kanjani?". Yisiphi isibhakabhaka sokukhetha ingane esikoleni, futhi sizoqonda isihloko sethu.
I-microscope yesikole: izici zokuzikhethela
Ukuqala ngokukhetha i-microscope yengane yesikole, abazali bazoqala ukukhetha ukuthi yini le nsizakalo engavumelekile ezoyisebenzisa. Kungenxa yalokhu ukuthi isigaba sedivayisi futhi, ngenxa yalokho, izindleko zayo zizoxhomeka. Uma kungumbuzo wokuzibandakanya kwengane kuqala ne-microcosm, khona-ke kungenzeka ukuba ukhethe okubizwa ngokuthi ama-microscopes ezincane, okungenani okungenani amathuba, kodwa futhi ubeke kancane. Uma i-microscope iyadingeka ekuqeqesheni, kufanelekile ukuthenga isibalo semakrofoni esikoleni (semfundo). Amakhamera amancane esikoleni anganikeza ukwanda kufika ku-650x. Okuthandwa kakhulu phakathi kwamakroscopes esikoleni yilezi ezilandelayo:
- ama-stereomicroscopes;
- microscopes eziphilayo ze-monocular.
Yilokho phakathi kwalezi zinhlobo ezimbili zezinkanyezi ezincane okukhethwa kukho lapho kuthenga i-microscope yengane yesikole. Ziyini ezahlukene? Umehluko phakathi kwala madivaysi, ikakhulukazi entweni yokutadisha. Ama-stereomicroscopes aklanyelwe ukutadisha izinto ezinkulu kakhulu, njengezinambuzane. Banikeza ukwanda okuncane, kodwa abanalo umbono obhekene nomthwalo, ngoba ingane ibabheka ngamehlo amabili ngesikhathi esisodwa. Ngaphezu kwalokho, ama-stereomicroscopes e-binocular enza kube lula ukuthola isithombe sesithathu. I-microscopes ye-biocological biological ine-magnification enkulu, ngakho-ke vumela ukucabangela izinto ezincane: izinwele zezilwane, amaseli ezitshalo, izingxenye ezincane zezicubu ezihlukahlukene. Kodwa kulokhu, ama-microscopes e-monocular anika umthwalo omkhulu wombono futhi kunzima ukusebenza, ngoba ingane yesikole ngokwayo kuzodingeka ilungiselele amasampula ekutadisheni: ukwenza izinhlayi, ukugcoba nokomisa izidakamizwa, njll.
Uma ukhetha imodeli yamakrofoni esikoleni, akuyona into engafanele ukulalela ukunakekelwa kwayo. Ngokuvamile zonke izinkinobho ezincane zanamuhla zinezibani ezakhelwe ngaphakathi, okuvumela ukuhlola kangcono into yokutadisha.
I-microscope yesikoleni
Olunye uhlobo lwama-microscopes esikoleni yizinhlamvu ezincane zedijithali. Kuyinto idijithali ebiza kakhulu, kodwa nayo inamathuba amaningi. Okokuqala, i-microscope yesikolo yedijithali ikuvumela ukuba ubonise isithombe kumqapha wekhompyutha. Ngakho-ke, ingane ayikwazi ukuthola kuphela isithombe esibanzi sento esithakazelisayo ngosizo lwe-microscope, kodwa futhi ulondoloze isithombe esilandelayo sokuqhubeka nokufunda noma ukuhlela. Lokhu kukuvumela ukuba ulandele izinguquko ezenzekayo ngenjongo yokubheka ezinkimbini. Okwesibili, i-microscope yedijithali iyiselula - ingasuswa kalula ku-stand, idluliselwe kusuka endaweni ngezindawo, ngaleyo ndlela ithole umfanekiso owandisiwe wento ethile ekamelweni. Ngakolunye uhlangothi, lokhu kungukuthi
Kubiza okungakanani inani le-microscope lomfundi?
Kuye ngokuthi imodeli ekhethiwe, ukuthengwa kwe-microscope yesikole kuzodala abazali ku-40 kuya ku-500 amayunithi avamile.
Yiqiniso, i-microscope ayifakiwe ohlwini lokuthengwa okuphoqelekile esikoleni , kanye nezincwadi, amacala epenseli kanye ne-backpack, kodwa ukutholakala kwayo kuzosiza ingane ngokuthuthukiswa kwayo yonke indawo.
