1. Green building (also known as green construction or sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle 2. Sun panels Buildings built primarily with wood will have a lower embodied energy than those built primarily with brick, concrete or steel Press tap Power saver light Bulbs Skylight Green building designs Wood Hut: this hut is made up of wood, (wood is a renewable resource) it is a very good insulator, and provides less pollution. The procces of using making bricks it uses a lot more energy. Push tap: A more environmentaly friendly tap as it does not waste water, because as you leave it closes automatically, you cannot forget to close it. Motion sensor lights: these lights are power saving lights, if someone is walking into a room the motion sensor will pick them up and then it will automatically switch off, it does not waste power. Sky light: this is green because it cancels out all electricity entirely, because it uses the suns power and light, A downside to this is that it does not work at night. Reservoirs and Astros: The reservoir pump water onto the astro, the water runs through the astro and runs back into the reservoirs. This works on the concept of recycling which is very green Thatch roof: This saves a lot of money, thatch is a very good insulator so no aircons or heaters are needed. There is much less energy used in this procees of making thatch roofs. Un-Green building designs A very un-green design as there are eight switch operated fluorescent lights in close proximaty. They are all on even though it is broad daylight. This is a huge waste of energy. This has a simple solution replace these lights with power saver or motion sensor lights or even just having less lights. Very unefficient electric pool heaters, They are not green because of the amount of electricity used and there is pollution caused, a solution to this problem is to just use pool covers or solar panel heaters. Classroom aircon/heater: this is un-green as it provides pollution, it uses water, a solution would be to us better insulators when building buildings such as thatch and wood. A leaking pipe: This is very un-green which is wasting a very precious non-renewable resource. A solution to this is to use better pipes and to fix this very quickly.

Activity 4 Poster

Activity 4

1) An informal name for a United Nations conference held to discuss environmental and energy issues. 2) United Nations 3) 1992 4) Rio de Janeiro 5) Rio de Janeiro (20 June 2012) 6) For the UN to discuss and find solutions to the environmental and energy issues. 7) Actions, by the UN, to phase out ozone-depleting chemicals and to create a permanent fund to help developing countries do the same 8) To protect and maintain the earth in a liveable condition for future generations. 9) Yes, it created things that do not damage the earth, like getting electricity from water or allowing us to think of using bio mimicry to not damage the earth. 10) The earth summit finds different ways in which we can stop using our non-renewable, ozone damaging resources and on way is using sustainable development, where natural (ozone friendly), renewable resources are used, like sunlight or water.

Activity 8

Activity 8 1. African Nationalism is to fight colonialism and demand independance from the colonizers 2. • ANC (1912) • National Congress of West Africa (1920) • African people's organisation (1950) 3. Pan-Africanism is a movement for greater co-operation among Africans and to unify. 4. Africanism is about the independents in AFRICAN countries whereas Pan-Africanism is the movement to unite all Africans. 5. They were great leaders who encouraged Africans to unite as they all came from Africa. 6. The song reflects how Africans were ‘stolen’ from African (as salves) and forced to America where they were brave and strong and had become a nation on their own there, to one day return to Africa.
