Te Paemahana

Hei Whakarāpopoto

Ka āta tirotiro i te taputapu ine-mahana, me ētahi horopaki e pā ana ki te paemahana.  Ka whai wāhi atu ko te tau tōraro, te ōwehenga me te tuhi kauwhata.  Ko ētahi wāhanga o tēnei kōwae ako he mea tiki atu i te kōwae ako reo Pākehā Cool Times With Heat.

Hei Raupapa I Ngā Mahi Ako

Hei Tīmatanga

Ko te mahi tuatahi, he whakawhitiwhiti kōrero mō te ine-mahana.

  1. Hangaia tētahi ine-mahana, ka whakawhitiwhiti kōrero ai he pēhea te mahi a te ine-mahana.

    Ngā tohutohu:

    Rīngia he wai whai kano (whakamahia he kano kai) ki roto i tētahi kotimutu.  Kuhuna he ngongo karaehe ka taupoki ai ki tētahi puru.  Whakamahanatia te wai i roto i te ipu (mā te kōpai ki ō ringaringa, mā te ahi rānei).  Ka piki atu te taumata o te wai i roto i te ngongo nā te mea ka rahi haere te wai ina whakamahanatia.
  2. Tirohia ētahi ine-mahana tūturu, ka whakawhitiwhiti kōrero ai mō te āwhata.  Anei ētahi tauira pātai:

    He aha te paemahana iti rawa e whakaaturia ana ki te āwhata?

    Koirā te pae makariri rawa atu e taea ana te ine ki tēnei ine-mahana.

    He aha te paemahana wera rawa atu o tēnei ine-mahana?

    He aha ngā tohu e whakaaturia ana ki te āwhata o te ine-mahana?

    Kāore pea e kitea ana ia tākiri, he mawhiti-tekau pea te whakaatu i ngā tākiri o te ine-mahana.  (Tirohia te Whārangi Mahi 1,(PDF, 124KB) kei reira ētahi tauira ine-mahana hei tirotiro, hei mahi mā ngā ākonga)

    He aha te tikanga o te 0º me te 100º.

    Koirā ētahi pūwāhi matua o te āwhata ine-mahana.  Ko te 0º te pūwāhi tio, arā, te wāhi e huri ai te wai hei tio.  Ko te 100º te pūwāhi e koropupū ai te wai.

    He aha te tikanga o ngā pūwāhi kei raro i te kore tākiri (0º)?

    Koirā e tohu ana he makariri ake i te pūwāhi tio, pērā i te pae makariri o te whenua tio i te tonga o te ao.  
  3. Whakahaerehia tētahi whakamātau kia kitea ai he pēhea te roa kia tau atu tētahi ine-mahana ki te paemahana tūturu o tētahi ipu wai.

    Ngā tohutohu:

    • Rīngia he wai ki roto i ētahi ipu e rua.  Tētahi he wai mahana (mai i te kōrere wai mahana), tētahi he wai makariri, engari me rau atu anō ētahi poraka tio.
    • Kuhuna te ine-mahana ki roto i te wai.  Tirohia te paemahana o te wai i ia 5 hēkona, ka tuhi ai ki tētahi tūtohi pēnei:

    • Whakaaturia ngā inenga paemahana ki tētahi kauwhata rārangi, ka whakawhitiwhiti kōrero ai mō ngā whakakitenga.

    He wā poto kia piki atu, kia heke iho rānei te paemahana o te ine-mahana ki te mahana o te wai.  I muri i te 25 hēkona ka mutu te piki haere te heke haere rānei o te ine-mahana, ka tau atu ki te paemahana tūturu o te wai.

    Hei Whakahīkoi i te Kaupapa

    Whakatūria kia toru ngā pou mahi i te akomanga, kia toru anō ngā rōpū ākonga.  Mō te roanga atu o te wiki, ka huri haere ngā ākonga ki ngā pou mahi e toru. 

    Pou Mahi 1 (PDF, 140KB)

    Hoatu ki ngā ākonga tētahi tūtohi e whakaatu ana i ngā paemahana o ētahi tāone nui o te ao i tētahi rangi.  Ko tā ngā ākonga he waitohu i ngā tāone ki tētahi mahere whenua, ka tuhi ai i te tāone me te paemahana.  Kātahi ka whakawhitiwhiti whakaaro mō ngā take e rerekē ai te paemahana i tēnā tāone i tēnā, ā, ka whakaaturia ō rātou whakaaro ki ētahi whakaari raraunga.  Me tono hoki ngā tamariki ki te whakamārama i tā rātou rautaki mō te tātai i te rerekētanga o te paemahana mōrahi me te paemahana mōkito o ngā tāone.

    Pou Mahi 2 (PDF, 109KB)

    Ko te mahi i konei, he tirotiro i te tere o te whakamātao o te wai.  E rua ngā pātai hei āta tirotiro:

    • He tere ake te whakamātao haere o tētahi ipu wai nui, o tētahi ipu wai iti rānei?
    • He tere ake, he pōturi ake rānei te whakamātao haere o tētahi ipu wai mēnā ka tākaitia ki te nupepa.

    I mua i te tīmatanga o ngā whakamātau, me whakawhiti kōrero mō ngā pātai e rua nei, ka whakatakoto ai i ētahi whakaaro.

     Pou Mahi 3 (PDF, 101KB)

    Ko te mahi i konei, he tirotiro i te paemahana mēnā ka whakaranua ētahi ipu wai e rua, tētahi he āhua wera, tētahi he āhua makariri.  I mua i te whakamātau, me whakawhitiwhiti kōrero mō ēnei pātai nei, ka whakatakoto ai i ētahi whakaaro:

    • E rua ngā ipu wai, he ōrite te rahi o te wai ki ia ipu.  E 40º te mahana o te wai i tētahi o ngā ipu, e 20º i tētahi.  Ina whakaranua ngā ipu wai e rua he aha te paemahana o te wai?
    • E rua ngā ipu wai.  E 40º te mahana o te wai i tētahi o ngā ipu, 100mL te rōrahi.  E 20º te paemahana o te wai i te ipu tuarua, engari e 50mL te rōrahi.  Ina whakaranua ngā ipu wai e rua he aha te paemahana o te wai?

     I te mutunga o te wiki ka whakahuihui i ngā ākonga ki te whakaatu i ā rātou mahi, ki te whakawhitiwhiti i ngā whakaaro i hua mai.
