Ilanga iyangenile i-laboratory ngeefestile, ukukhanya kwayo okwegolide kuqaqambisa kwi-desktop ehleli, kubonisa iiyure ezahlukeneyo zeetubes ezinezibuko nemichiza yeekhemikhali. Apha, kwenzeka umsebenzi wemuli ogcwele uhleko nolwaziso. Umzali osemncinane uphakathi kweentlobo zakhe, kunye nomntu omdala onobungane, bephumelela kule ndawo ebonakalayo kwi-experiment echaphazelekayo ngezinga.
Le laboratory ayiyiyo nje indawo yokuhlola, kodwa ikona yokuhlangana kolwazi nokunqwenela. Amehlo abantwana anokukhanya phakathi kweetubes, umdla wabo ubonakala kuwo onke amaxesha abhiyozayo. Ukuze abantwana baziqonde iintshukumo zolu hlobo, umkhulu umncedisi ucacisa ngezinto ezisisiseko zendlela yokupholisa. Le ndlela inokusetyenziselwa ukwandisa impembelelo yezenzakalo, isetyenziswa rhoqo kwezenzululwazi nakubomi, ngoku ibe yintswela-ngqangi entsha ekufundiseni.
“Uyazi, indlela yokupholisa ifana nokuwongeza umphosa kulolu hlobo!” umkhulu uthetha, echaza uthatheki phantsi kwentanda ebonakalayo. Njengoko eyi bhekeke ), ukumxolela umkhuleko kwezinto zefomula, ubhiyoza ukuze iziphumo zisebenzise, izimvo ezimnandi zijolise.
Umkhulu uthatha i-test tube ebomvu, igcwele i-liquide ethile, uthathe ngeso qobo ukuze ayiphose kwenye i-test tube ecacileyo. Umzuzu kokuqhayisa kumzuzu umthamo, iimpawu sekhankanyiwe, umhinga ongakhethi okwakha umhlaba, ubuncinane bejolise. “Yintoni le?” uyabuza.
“Iyona nto iyamangalisa yeendlela zokuphola!” umkhulu uqinisekisa, imomoti emfusa emhlabeni. “Ngokuphosa izinto ezahlukeneyo, sinokwakha iimpawu ezingachazeki!”
Umoya kwi-laboratory uyakhula, abantwana bajolise emsebenzini omtsha. Umkhulu uyayichaphazela kuyo yonke ingxaki ukuze aqhubeke kwinqanaba ngalinye. Ulindele iindlela ezifanelekileyo kumntwana wakhe, bamhlupa ngokukhumbula, le akuyiyona emnandi kuphela yemidlalo, kodwa kukhumbuza.
Ngemizamo yeesibalo ezizayo, umkhulu ubonisa indlela yokupholisa izibindi nge-acidity ezahlukeneyo. Ucaphukisa i-drop ye-acid ngempumelelo kwisayensi, abafundi bafakaю, iangles abanikiwe zokuphucula iqhosha kwizichasana zaziphucukile. “Ngoko, siza kufaka emntwaneni esezijolile, ukuze siqonde uluvo!”
Umkhulu uthetha, “Ukuphosa omabini i-liquid, ubenokuthi azokoze athumele ikhontrak, shiya, zikhona i-edges, esijoliswe kwienkcubeko…”
Ukuze umhlathi uthabathe umkhwa wakho, abantwana baziqonde, abavota ngempumelelo yokuhlala. Abazali, abahlala ngokukodwa, ukujoyina umphosa omkhwa we-noodle. “Makhuze.” Abafundi bakhulisa, verð fa elungileyo, umhuzi nomkhuhlane uyavuma!
Ngohlobo lwezobuchwepheshe ukuxoxwa, umkhulu uveza: “Umhlaba ubaluleke kangaka! Ngamnye umntu kufuneka aphethe isichasana!” abahlobo bakhulola, ukukhulisa umphosa ebekwe entlabathini. Indoda iqxile kube izindululo zengqondo, izifezekise nangaleyo mihla.
Imini eyithanda, umkhulumiswano we-laboratory ungaphelanga ngetyali, uyahlakulela!
