Nomntwana na kodwa uyazi ukuba yintoni loo ikhangeleka ngathi ngemicroscope, ulwimi efikelelekayo achaze injongo yawo kwaye uqinisekise ukuba umntwana umdla.

Products labavelisi isisiTshayina cheapness zawo ayikwazi akusoloko ukuzithethelela nokuba ngendleko ephantsi. Musa ukukholwa, ukuba iphakheji microscope abantwana Chinese ibonise ukwanda ngaphezu kwezihlandlo ezingama-300. Kuba kuluhlu iimveliso ixabiso ku $ 60 akunjalo ngokukhanya ezikumgangatho ophezulu, ukunyuka aphezulu amanani - akukho ngaphezu kokuba zithutha emaphepheni.

ukuthenga baby

Ukuba umntwana isekhona detsadovets ukuba isixhobo umfundi ukuthenga ekuqaleni. Njengoko zokudlala abantwana kokuya esikolweni yobudala kungcono ukukhetha imodeli "Young eziphilayo 40" okanye "yabantwana ngemicroscope DMS-1". Ezi zixhobo ezilula abe ulwando oluphindwe-40, nto leyo kakhulu ngokwaneleyo ngumphandi oselula, ukuba ube ifomu elula kunye noyilo ezinzileyo, kunye nexabiso eliphantsi.

Kukho nkqu iimikroskopu udumo for ladies abaselula, eyenziwe intombi ekhethekileyo (umz, epinki) uyilo. Ezinye zazo compact gqith microscope kunye mini-iteleskopu ukuba ungalunga epokothweni yakho.

ukuthenga umfundi

Lo mntwana mdala, unako ukuthenga ngemicroscope kunye ukukhulisa aphezulu okanye imodeli yedijithali, nto leyo iba umda enkulu ngenxa nokuhlola. Abantwana iimikroskopu baxhotyiswa izibane, iindondo zokhuseleko, izihluzi umbala. Ikhithi kuquka yonke into efunekayo ukuze isebenze izixhobo kunye izincedisi ze-experiments.

Umzekelo ngemicroscope zokudlala abantwana abangaphezulu kweminyaka 8 kuba ongumzekelo ukunyuka ukusuka 100 ukuya 300 lunemiba, ezenziwe ngezinto ezomeleleyo kwaye axhotyiswe ngeglasi optic, ukuhla nokunyuka kunye nokukhanya. Glass lens zinika Obusemagqabini ubunjani umfanekiso. Esi sigaba esikhanyayo LED isibane.

Yeendleko zezi iimikroskopu - ngokuqhelekileyo kummandla enye enesiqingatha amawaka engange.

Yintoni ukujonga ukuba xa bethenga

Ukuba isigqibo ukuba kuthengwe kunye ixabiso eliphezulu, iyavakala ukuqwalasela indlela ethile. khulu Abantwana bangena ngaphakathi kunye amazwe (ikakhulu Chinese). Ukuba sinikele ingqalelo yokukhanya. Ukuba lens zeplastiki, xa ucoca baya phina. Lens kunye nokwanda encinane, ingakumbi amaTshayina, ngokufuthi musa ukunika umfanekiso ocacileyo - umtshato.

Ukuba ukhanyiso lwenziwa ngokugqitha ibhalbhu ezingqengezelayo, mhlawumbi ingaphumeleli. Kungcono ukukhetha lelo LED. Kungcono ukuba isipili yi ilayithi egosogoso - ukugxila ukukhanya okukhulu. Kufuneka esisigxina kakuhle yaye bakhuselekile imikrwelo.

Eyepiece lens ilens kufuneka ingakumbi kwiglasi. Ukususela lens ixhomekeke ukuxazulula amandla kunye nomfanekiso esemgangathweni. Tube nokuma microscope kuya kuba ngcono ukuba i intsimbi. Aqaqambileyo ilayithi LED kufuneka lilawulwe. Ngokungafaniyo ibhalbhu ezingqengezelayo, ii-LED ukunika ngakumbi ukukhanya bendalo yaye akukho nobushushu, ngoko ke zithembeke ngakumbi.

ezongezwayo zokuzikhethela

Iyafuna ukunikela ingqalelo isixa ethengiswa iseti izincedisi, lula ukusetyenziswa kunye nokugcinwa, kwakunye ubukho imiyalelo ezinengqondo ngakumbi. imifuziselo nezolo iimikroskopu zabantwana akholisa iyathengiswa iseti kunye nezincedisi ezininzi eziluncedo zenzelwe ukuba sijonge izinto unqwenela intliziyo yakho. Ngamana iqhotyoshelwe ukuba ukubukela kunye neesampuli, ezifana uboya kunye nezilwanyana iinwele m. P.

ngemicroscope zabantwana, eziquka iinxalenye zeplastiki, ukuthenga umntwana oselula uyagwetyelwa ukuze akhuseleke. Abantwana abadala kancinci Kucetyiswa ukuba le modeli ngeglasi lens slide yeglasi. Ukongeza, iisampulu zidla ukuze ziphicothwe abantwana ukuba sizilungiselele abazali.

Yintoni enye abazali kufuneka bazi

Ukumisela isixhobo kunye nokulungiselela kwamachiza - inkqubo ngokwaneleyo ezibalulekileyo. Njengalo okanye akunjalo, ngumsebenzi lwabazali kunye nendima kwabantwana - Phaphani, phulaphula, ucacise zivalele ulwazi olutsha.

Ngemakroskopu, ukuba ukukhulisa eliphezulu, kufuna ezinye amava. Kuba amalinge yesiqhelo, kwanele ukuba sikhule amaxesha-40 ukuya 200. Kukholelwa ukuba enqwenela umdla kakhulu umntwana imimangaliso biology, iyavakala ukuthenga microscope zonyango omdala ekhaya, elebhu okanye yoshishino. Le khulu zingathengwa ezandleni zikwimeko entle. Ukuba uthenga izinto zokudlala Chinese, musa ukugxotha ukukhulisa phezulu, kungcono ukuthatha unonophelo olusemgangathweni sokwakha kunye lula kokulungisa.

Cogwheels kwemakhroskophu ukuqhuba ngokulula rhutyu kuthelekiswa enye kwenye ngenxa kuzakuthothisa eziya kufuneka kutshintsha iminyaka embalwa yokusebenza. Kwezinye iindawo ezihamba ulawulo ixinene kakhulu, kwaye kungonakalisa iivili.

WaBantwana khulu: ncomo

Ngokutsho abathengi, iimikroskopu, njengoko umgaqo, bahambelana ukusebenza ebhengeziweyo. Uzilungise kungcono ukuba abadala, njengoko kufuneka nocoselelo kunye nokulawulwa kakuhle. Abantwana ngomdla omkhulu, bejonge iisampula enikiweyo loboya, kwakunye engenakubalwa iswekile netyuwa. Ngenxa okucoca umbala ziikristale yetyuwa eqhelekileyo khangela mhlaba kumnandi yesiqalo.

Okunye abathengi ukubuyekeza kwabo bakhalazela ngokumisa ubunzima, ingakumbi imodeli Chinese, cinga ukuba, njengokuba wazama, siye wasilela kukuzuza ubulunga umfanekiso elungileyo. Abanye abathengi baye bagqiba kwelokuba iimikroskopu cheap Chinese ezifanelekileyo kuphela ukonwabisa ungumntwana yobudala senior kokuya esikolweni, kwakunye incwadi umfundi amagqabi kangako. Kodwa ke inkoliso yabo beza kwisigqibo sokuba ixabiso lowu abantwana ngemicroscope (feedback enikwe ngale ndlela 'microscope for Schools (9001 PS) ") luyahambisana na injongo yawo kwaye ingasetyenziswa kwizifundo biology.
