Whakawhitiwhiti kōrero mō tēnei mea te kītanga o tētahi ipu. Arā, he ine i te rahi o te wai e taea ana te whakauru ki taua ipu. Whakaaturia etahi atu ipu, kia rerekē te āhua me te rahi o aua ipu. Tonoa ngā ākonga ki te raupapa i ngā ipu, mai i te mea he iti rawa te kītanga, ki te mea he nui rawa.
Whakaaturia tētahi ipu miraka 1L (kotahi rita) te rahi. Whakawhitiwhiti kōrero mō te waeine rita.
Tonoa ngā ākonga ki te whakarōpū i ngā ipu, arā: · ngā ipu he iti ake i te ½L · ngā ipu kei waenganui i te ½L me te 1L · ngā ipu kei waenganui i te 1L me te 2L · ngā ipu nui ake i te 2L

Anei tētahi ipu. Ko te rahi o te wai e taea ana te whakauru ki roto, koirā te kītanga o te ipu.
Anei ētahi ipu, he rerekē te āhua, he rerekē hoki te kītanga o tēnā me tēnā. Āta tirotiro i ngā ipu, ka raupapa ai mai i te mea he iti rawa te kītanga ki te mea nui. Tuhia te raupapatanga ki te Whārangi Mahi 1 (PDF, 80KB). Me pēhea te whakamātau i tō raupapatanga? Āta whakaarohia tō whakamātau ka mahi ai. Tuhia ki te Whārangi Mahi 1 (PDF, 80KB). I tika anō tō raupapatanga? He ipu tēnei, kotahi rita te kītanga. Ko te rita, koirā te waeine matua mō te kītanga. Whakamahia ai te rita puta noa i te ao. Ko te ‘L’ te tohu poto mō te rita.
Me titiro anō ki ngā ipu i raupapahia. Wehea ngā ipu kia whā ngā rōpū. Ko tētahi rōpū ko ngā ipu he iti ake i te haurua rita. Tētahi ko ngā rōpū kei waenganui i te haurua me te kotahi rita. Tētahi kei waenganui i te kotahi me te rua rita, me tētahi mō ngā ipu he nui ake i te 2L te kītanga. Tuhia ngā rōpū ki te Whārangi Mahi 1 (PDF, 80KB). Whakamātauria tō whakarōpū i ngā ipu. I tika anō tō whakarōpū?

Whakawhitiwhiti kōrero mō te ritamano (mL). Tūhuratia te pātai he pēhea te rahi o te ritamano? Whakaaturia ētahi ipu kua tuhia ngā kītanga ki te ritamano (mL). Hei tauira, ko te pouaka wai ārani (700mL), ko te pātara waina (750mL) me ētahi atu.
Hoatu te Whārangi Mahi 2 (PDF, 78KB) hei whakaoti mā ngā ākonga.

Ko tētahi atu waeine mō te kītanga, ko te ritamano. Ko te mL te tohu poto. He pēhea te rahi o te ritamano (mL)? He waeine tēnei e whakamahia ana hei whakaatu i te kītanga o ētahi ipu. Tirohia ngā ipu nei, he aha te kītanga o ia ipu. Whakatairitea ēnei ipu ki te ipu miraka kotahi rita (1L) te kītanga. Ki tōu whakaaro, e hia ngā ritamano i te rita kotahi? He iti ake te 750mL i te 1L, he nui ake rānei? E hia rita e rite ana ki te 750mL? |
- Ko te mahi ināianei, he whakatau tata i te kītanga o ētahi ipu, he ine i te kītanga, ka whakatairite ai ki ngā whakataunga tata. Kātahi ka ine i te papatipu o te wai e taea ana te whakauru ki ia ipu, me te whakatairite anō i te papatipu me te kītanga. Mā konei e kite ai te ākonga he rite te papatipu o te kotahi rita (L) ki te 1kg.

He mahi takirua, takitoru tēnei. Hoatu ki ia rōpū ētahi ipu e rima, kia rerekē te rahi o tēnā me tēnā. Tohua ngā ipu ko A, ko E, ko I, ko O, ko U. Hoatu hoki tētahi ipu ine-kītanga me tētahi ine-papatipu.
Whakamāramahia ā rātou mahi, ka hoatu ai i te Whārangi Mahi 3 (PDF, 88KB)
Mēnā he tōtika ngā inenga a ngā ākonga, ka kitea te tauira he rite te kītanga (mL) ki te papatipu (g). Kōrerohia ngā hapa ine tērā pea ka puta.

Anei ētahi ipu e rima, he rerekē te āhua me te rahi o tēnā me tēnā. Kei runga i te whārangi mahi ngā tohutohu. Arā: · he whakatau tata i te kītanga o ia ipu hei mL · he ine i te kītanga o ia ipu – mā tō rōpū e whakaaro me pēhea e ine ai · he whakatau tata i te papatipu o te wai ka taea te whakauru ki roto i ia ipu. · he ine i te papatipu o te wai ka taea te whakauru ki roto i ia ipu – mā tō rōpū e whakaaro me pēhea e ine ai
Ka mutu ā koutou mahi ka whakawhitiwhiti kōrero tātou mō ngā hua ka puta.
