I-Chemistry iyindaba ehehayo, kodwa eyinkimbinkimbi. Futhi uma isikole futhi sasingenazo izesekeli zokuhlola, kungashiwo ukuthi wayedlule. Kepha kukhona okuthile umuntu ngamunye okufanele anciphise okungenani. Leli itafula le-mendeleev.
Kwezingane zesikole ukuze zikufunde - ukuhlukunyezwa kwangempela. Uma bekubona emaphusheni, khona-ke kuphela ubusuku obudala. Izinto eziningi kangaka, inombolo yakho ngayinye ... Kepha umama oyedwa omkhulu weza enendlela yokuzijabulisa, indlela yokufunda itafula le-mendelev. Ilungele izingane kanye nabantu abadala, futhi uzokutshela ngentokozo ukusabela "kulula kakhulu!
Ithebula lesikhathi sezakhi zamakhemikhali
Njengokuhlangenwe nakho kukamama wezingane ezine uKarin Tripp, unendlela efanele kungenzeka ukuthi ufunde konke. Ukuletha izingane ezincane esifundweni samakhemikhali, wanquma ukuguqula itafula lezikhathi zezinkundla ezisensimini yasolwandle.
Umdlalo uqukethe amakhasi amane anethebula le-mendeleev - amabili kumdlali ngamunye. Umdlali ngamunye etafuleni linye kudingeka adonse imikhumbi yakhe, futhi ngakolunye uhlangothi - ukucacisa izibhamu zawo futhi angqongqoze amakhoyili womphikisi.
Imithetho yokulwa yasolwandle iyafana nakumdlalo wakudala. Ukudubula kuphela isikebhe sezimbangi, udinga ukubizwa ngokuthi inombolo ye-10, kepha into efanelekile yamakhemikhali.
Le ndlela izovumela izingane ukuthi zingagcini nje kuphela ukuthi zifunde amagama ezinto zamakhemikhali. Inikela ekuthuthukisweni kwememori nokucabanga okunengqondo. Ngemuva kwakho konke, izingane zizohlaziya izinombolo nemibala elungiselelwe.
Ukuze izingane ekuqaleni bekulula ukuthola into oyifunayo, imigqa namakholomu kufanele ibalwe yizinombolo. Kepha, ngokusho kukaKarin, izingane zakhe, ngemuva kwezinsuku ezimbalwa zomdlalo empini "yamakhemikhali yasolwandle", waqala ukuhamba etafuleni le-mendelev. Baze bazi ngisho nezinqwaba ze-athomu kanye nezinombolo zokulandelana kwezinto.
Ngokuhamba kwesikhathi, imithetho yomdlalo ingaba yinkimbinkimbi. Isibonelo, ukubeka umkhumbi kuphela ngaphakathi komndeni owodwa wezakhi zamakhemikhali.
Ngisho nendodakazi eneminyaka eyisishiyagalombili enomuntu oqalayo umama ongenisayo, ongafundanga amakhemikhali esikoleni edlala lo mdlalo ngentokozo. Futhi kubantu abadala, le yindlela enhle yokusebenzisa isikhathi.
Wonke amakhasi etafula le-mendeleev ngokudlala impi yasolwandle angaphrintwa kwiphrinta ejwayelekile noma yemibala futhi usebenzise inani elingenamkhawulo lezikhathi.
Sakholelwa, uDmitry Ivanovich MendeleV angayazisa le ndlela yokufunda umsebenzi wakhe.
