Arià Canadell: Global warming
Presentation (10%)	Do you use any resources? Are the resources relevant and attractive and focused on the topic? Do they support your presentation? Is the timing 5-7 minutes? The presentation was correct in my opinion because it supported the content of the explanation and it had photos of all the causes-effects we explained.		10
Body language and eye contact (10%)	Are you looking at your audience most of the time? Are you reading occasionally from your notes? Are you doing any gestures / movement to hold the attention of the audience? I'm always trying it but while I'm nervous I can't control my eyes at all. Then I read at last a pair of sentences that I think is very normal.		10
Structure (10%)	Do you organize your ideas in order of importance? Do you use discourse markers to make your ideas more clear? Well, instead of organize the ideas in order of importance we had organized them in causes and effects of the global warming.		10
Content (40%)	Do you introduce interesting, NEW information to your audience? Is your information detailed and clear? Do you give / show examples? Is your information copied from a source or is it original? Did you look up information/facts/ideas in the Internet/books…? We didn't introduce new information because a week before other group explain the global warming so we repeat much information. We addapted internet's information but we only could make a little summary without a lot informtion, it didn't contain any examples because we couldn't find them....		20
Language (20%)	Is your grammar correct, complex? Is your vocabulary rich and varied? Do you use sentence linkers? Do you use pause fillers? The grammar was easy to understand and to memorize, the sentences were good stuctured but I don't know if I changed some sentences during the presentation to the class.		10
Pronunciation and intonation (10%)	Do you know how to pronounce all your words? Did you check the pronunciation with a dictionary, a classmate or the teacher? Do you change your tone of voice or use a monotone tone all the time? Did you speed in a fluid continuum or with breaks and interruptions? I check difficult words in the dicctionary and other ones that I asked to Christian. My pronunciation in the explanation wasn't perfect of course but I try to pronunce all the "complex" words good.		5

Oral presentation

The right definition of “global warming” is, as you probably know, the rise in the average temperature of Earth's atmosphere and oceans since 19th century and it will rise more and more if we do nothing.

Scientists have spent decades looking for what is causing global warming. They've looked at the natural cycles and events that are known to influence climate. The only way to explain this rise of temperature is including the effect of greenhouse gases emitted by humans. We produce too much carbon dioxide, the vegetation can’t transform all the carbon dioxide so the gases are being kept in the atmosphere. How you can see in the second photo less re-radiated heats escapes into space. So the energy is not escaping well from the earth and we keep temperature. Our greenhouse effect that usually protect us, now are raising energy levels, but it’s our fault. 

How you can see in this graphic the temperature is rising very slowly.  But this little change supposes big effects. Now Marc will explain some of the most important global warming’s effects on the earth.

All in all we have to say that our presentation was a bit similar to Ana’s and Xantal’s presentation because the topics were very related. Maybe we can say that humans are killing the earth with our pollution, in my opinion now we can do nothing because we are young and is very difficult that a simple person could make sense to a big company that they have to change. But we can give support to a NGO, working for them or giving money to them.   

Finally we will show a you little video related with the effects of global warming
