The last work in english of the year was a poster session :
We had to make a poster about a subject choosen by our group. Mine was about the causes and consequences of global warming. Even if we ever studied that in classes, i think it’s important to make researches about this because the phenomenon is increasing and it’s dangerous for the young generation who can be endangered by this (for exemple with the increasing of the sea level). And with our scientific knowledge we can understand how work the greenhouse effect for exemple.
Thanks to the work of my group i understand that if all the antartic ices melt, the will be 60m of water over the normal level of the sea !
And with the global warming, pimples developp too early in the winter, so they die in the winter and via phenomenon called food chain it’s all the ecosystem which is endangered.
So global warming is the main concern we have to consider.
I have asked questions about posters of other groups.
The first one was about renewable energy. It’s an energy generated from natural resources which are renewable on human life scale
There is :
-Solar energy. it consist in using a solar panel to catch rays and to transform it into energy.
-Geothermal energy. it uses volcans in order to extract caloric fluid from the earth but it requires a special place.
-Wind. There is turbines which run with the wind and that create electricity.
-Water. This is like with the wind but in the water but this kill a lot of fish so they go away (no fish land !)
-Biomass. It uses biomass as fuel or to produce bio-fuels.
Hydroelectricity represent more than 50% of the total.
The second poster was : “How will be the future cars ?”
There will be an adaptive cruise control, so they use radar and lasers to repear objects in front of the car, and infrared vision system.
So how it works ? It’s a detector of infrared, when it detect he made a thermogram, and it’s translated into electric impulse which is send to a chip and finally transformed to video screen.
The cars will be more lighter, so that there is less fuel spent. The cars will be made of aluminium, plastics…
There will be some HUD (Head Of Display) to indicate some elements on the road for exemple.
With this posters i learned a lot a things, and i practice my oral, so it was a good experience !
