Bonjour à tous,

Quelques dernières informations avant de nous retrouver dimanche soir.
Pour ceux qui ont fait des films de présentations, vous pouvez les télécharger sur ce blog, afin qu'ils soient facilement retrouvables le jour J.
Nous vous rappelons que vous devrez tous vous présenter dimanche soir entre 20h et 20.15h à Biarritz, avenue Charles Floquet, en face du parking "Charles Floquet", près de l'arrêt des bus municipaux "Chélitz".













Vous devrez tous avoir sur vous:
- des papiers d'identité en cours de validité.
- votre carte d'assurance européenne ou à défaut le nom et le numéro de votre police d'assurance.
- le petit carnet vert.

Ne pas oublier:
  • 1 serviette de toilette
  • une trousse de toilette
  • 1 paire de claquettes (chaussures pour se rendre à la douche)
  • lunettes de soleil
  • casquette
  • crème solaire (à partager car il est inutile de partir avec 22 tubes de crème solaire).
  • Ne pas garder de lime à ongle, ciseaux ou contenant de plus de 100ml dans son bagage cabine (ils vous seront confisqués avant de monter à bord).
  • Tous les bagages peuvent aller en soute. Cependant ne partez pas avec 23 kg de bagage, c'est inutile pour 4 jours...
  • Pensez à ne pas trop remplir vos bagages si vous souhaitez ramener des petits souvenirs...
A dimanche,
Les professeurs accompagnateurs restent joignables sur leurs portables.

SUNSCREEN

OUR PROJECT : SUNSCREENS


   For our project we have chosen to talk about sunscreen, so we asked ourselves if our sunscreen is it as efficient as a commercial sunscreen.

  So we decide to create a sunscreen with coco oil, olive oil, bee wax, and zinc oxide




 Protocol:
  
-put all the ingredients in the Erlenmeyer flask and mix

- heat in a bain marie until all ingredients are melted

-remove from time to time

-add zinc when everything is melted and shake





Then we tried our sunscreen with a uv lamp and uv captor, we measured the intensity of uv. Our sunscreen is efficient.

Soap

For this year our project is about soap. The key question is find a soap with the best respect of the skin. To find it, we made a cold soap, a hot soap, surgras soap, and a lot of soap.the pH need to be at 7 for a good soap for skin.

MICROSCOPE

We have seen a Youtube video. This video explains to us how can we use our smartphone as a microscope. This video is on the channel Tunisie Magazine, this video is titled "Comment transformer votre smartphone en microscope".

You can see our homemade microscope, on the top the phone is used to see some objects and on the bottom the phone is used as a light.
Under the phone used to see something there are different lenses with different magnifications.


We have done this projects with Yohan Guillemet, Nicolas Accaries and Antoine Leveque.

Crystals


 Our project consists of creating some crystals and specially make them pure.For that, we did some liquid and solid crystals, and every time we get geometric shaped crystals.

We changed factors to see if it had an influence on the crystal's purity. First we changed the solubility, by putting more or less metals in distilled water : We conclude that ours crystals were more pure with a solution at solubility stage because the solution is saturated at this point. Then, we changed temperature, it's at 0 degrees that we obtained the most beautiful, translucent, geometric and pure crystal.

Ours crystals are very small so we observed them into the microscope, so we had the idea of make them grow. So we did. 

In order to conclude, in our project we are looking for the best qualities of crystals.

Colorants

                                                                       Colorants

  Our project is about colorants. We wanted to do this project because we were wondering about uses of colorants and their dangers. We have done some synthesis, a lot of extraction (as like the extraction of M&M's). There you can see a photo about this experiment.



In this experiment, we wanted to show all colorants contained in the M&M's, identify these colorants and know more about the dangers of those colorants.
The problematic of our project is "What does colorants are used for and when can they be dangerous".
With this problematic in head, we have done an extraction of lycopene in the tomato sauce.
We have found that the lycopene in the tomato sauce could be dangerous for health but we must eat a enormous quantity to be sick.
Our project have done many extraction (in schtroumpfs...)
and we wanted to show you a video about dangers of Food Dyes. (the link of this video: https://www.youtube.com/watch?v=611hJOb4M0g)
