He whakatau kupu: whare pupuri mahana = green house, käpuni = gas;
karaehe = glass, paparanga kapuni = layer of gas, whakahau = encourage

Questions/instructions:

Ka hangaia te whare pupuri mahana ki te karaehe. Ka uru te mahana o te Rä ki roto, ä, ka mau. Nä te karaehe, he pöturi te puta o te mahana ki waho.

E ai ki ngä kaipütaiao, kei te mahana haere a Papatüänuku, përä i tëtahi whare pupuri mahana. Kua mau te mahana o te Rä ki raro i tëtahi paparanga kapuni. Käore e tukuna e te paparanga kapuni kia puta te mahana. Koia nei te take, kei te mahana haere a Papatüänuku.

Titiro ki te pikitia i raro nei, ka whakautu ai i ngä pätai.
   Glasshouses are usually warm because the glass lets heat in from the sun but slows it down from getting out.

Scientists believe that the earth is warming up just like a glasshouse. Warmth from the sun is being trapped under a layer of gases. These gases are stopping the heat from escaping. This is making the earth hotter.

Look at the picture and then answer the questions below.

Me pëhea e tutuki ai tënei whakaaro?

Some people want us to cut down the amount of gases going into the air.

How do you think this could be done?
reduce emissions from fires (domestic) and factories

11
reduce emissions by engines burning fossil fuel
(including use of car pooling, public transport)

11
change numbers of animals or their diet (or genetics)

2
reduce production and use of specialised gases
(e.g. aerosols)

13
absorb undesirable gases (e.g. plant trees)

Commentary:
Most students could identify one or more sources of atmospheric gases, but very few indicated more than one consequence of the earth getting warmer, and less than half identified any strategy for reducing omissions of atmospheric gases.
