science experiments

Avec leurs professeurs d'anglais et de documentation les élèves ont blogué en anglais sur le thème "science experiments".

Après avoir choisi une expérience ils ont rédigé la fiche explicative de l'expérience à partir des questions suivantes :
1-Why is  this experience or invention useful ? What is its usefulness?
2-What are the materials or products used?
3- What do you have to do to achieve the experience?
Can you describe precisely the different steps to achieve the experience or the invention?
4- What are the various difficulties met to achieve the experiment?
5- In which fields can we use this experiment? ( Industry, medical field, sports field, environment, everyday life…).
6- Explain the reasons why you chose this experiment and why it appealed to you?

Dans un deuxième temps, les élèves ont blogué et commenté les expériences pour élire la vidéo la plus...funny!!
Les professeurs : F. URVOY et L. JEAN

Magic snow

We have choose this experience named magic snow, it’s useful because it can absorb water and created Magic snow. We can reverse the process just by adding salt. This product can absorb 200 or 300 his weight of water on magic snow. To do this experiment the products used are water and sodium polyacrylate (you can obtain from disposable diapers or buy in a garden center) and salt. The differents steps for created magic snow are to put polyacrylate sodium on water and the result will be on few seconds. After this we can at any moment reverse the process just by adding salt The only difficulty met to achieve the experiment is to find sodium polyacrylate but this experiment can be used in everyday life if we have to absorb too much water or keep it. We have chosen this experiment because it is useful and it’s used on few products like diapers or to add viscosity and thicken some products for example in cosmectics. But we think than it can be more used by people in everyday l

1-Why is  this experience or invention useful ? What is its usefulness? 1 ) The invention is useful because it can give electricity at all of the world for the people who doesn’t have electricity 2-What are the materials or products used? 2 ) We need white or red vinegar, 5 piece of copper wire, 5 nails, Ice Tray, One led; safety glasses. 3- What do you have to do to achieve the experience? Can you describe precisely the different steps to achieve the experience or the invention? 3) To achieve this experience, you do :                    1-Wrap a nail with the copper wire like this for all the nails                   2-Fill up 6 sections of thr Ice Tray with a vinegar                   3-you should create a circuit by unserting each nail into the vinegar  like this                   4- Place the LED in between the section that contain only one nail and one wire 4- What are the various difficulties met to achieve the experiment? 4) The difficulties are the fact

1-Why is this experience or invention useful? What is its usefulness? This experience is useless for us. This experiment just serves to discover how the air is compressed. 2-What are the materials or products used? We just need a bottle and our hands. 3- What do you have to do to achieve the experience? Can you describe precisely the different steps to achieve the experience or the invention? For this experiment we need a bottle and take it normally and then turn it 8 times in the middle of the bottle then open the cap and a smoke (compressed air) comes out.     4- What are the various difficulties met to achieve the experiment? The difficulty here is to turn the bottle but once we have made a turn it is much easier. 5- In which fields can we use this experiment? (Industry, medical field, sports field, environment, everyday life…). Compressed air can be used to inflate a tire, stripping a paint surface: breathe under water. 6- Explain the reasons why you chose
