Hello, my name is Sarah, during this year, I work on a project. This project is to build a drone.
Our problematic is How create a drone by it self ?
We are four in our project, and it was very helpfull because we could help each other and doing pairs to work in different parts.

This is a picture about our drone : 

We call it VSL² because of the four first letter of our name (Vanille, Sarah, Laure et Léa)

We built it with two rulls from the lab and we use motors and engines what we have buy. We also learnt the programmation for control the drone and use an Arduino card (electronic card).

Our drone fly ! We had some problems to do this, but we succeed !

My Project !

Hello, my name is Léa and today I will introduce you my project.
This year with my friends we chose to build our own drone!

We used some lab's materials and we bought the battery or the esc for example to build it. We tried to follow a video about a man who was doing the same thing by itself but we decided to change it a little; We used an Arduino Card to control it instead of using a remote control. We had a lot of problems with the program and the battery but we finally succeed and we made it flies ! We were very happy and relieved.
We had so much fun during this project and we even gave our drone a name : it's called "VSL²" in reference of our initials.

We nearly have finished this project, no
w we have to write the lab's repport.


Our project is on the organic and industrial lipstick.
We wanted to create a organic lipstick, to show if a organic lipstick is must performant and resistant than the industrial lipstick.
We have to created our organic lipstick for a must environment, and for the healthy of poeple.
During our project, we did of experiences as the spectrométrie, presence of plomb, the difraction.
It's better the natural colorant for a lipstick because he is must resistant.
The report was made by Lucie, and i do the report with lucie on presence of plomb.
After we have all participated in the project.

Hello my name is Emily Harriet!

This year  with my group, we studied about electrolysis. Our key question is "How and why  can we depose a methal of an other methal ?"

During the project we carry out experiments. I found things to do a experiment which name is GALVANISATION.

 For this experiment I need:

-a balance
-a piece of copper
-zinc powder
- a hot plate
-soda powder
-a beaker
- water

In the first time, in the beaker heat 200 ml of water. Add 2.0g of zinc powder and 2.0g of soda powder, wait 2 minutes.
Then we introduce the piece of copper in the beaker. We need to wait 20 minutes. A few minutes later the piece of copper is totally covered of zinc.
In the second time, we place the piece of copper on the hot plate. 40 minutes thanks to the mixture the piece of copper has become bras.

Hello my name is Laure and I will explain my project. The key question of my project is : how to create a drone by it self ?
I wasn't alone in this project, I create it with Léa, Sarah and Vanille.
To create our drone we looked a video on Youtube to start. In this video a man create his own drone like our drone but not exactly. for exemple we replaced the remote controle by a arduino card.

We gave it a drone's name : VSL² in reference of our name's initials.

We faced a lot of problems but we find the good solution and now, it flies ! 

We have to write the lab report.

Vanille's project

Hi, I'm Vanille and i'll talk about my project of 2018.
With my friends we wanted to create our own thing, so we created a drone. Our drone is pretty basic, he has propellers, engines and ESC. The major difference is that he's controlled by an arduino card and even if it doesn't seem complicated, it was sure a lot of work ! it was very interesting, fascinating and fun ! We had a lot of up dans down, we thought that our drone would never fly so it was a beautiful surprise when he flew for the first time ! Everyone was very concerned when he flew on the first try, i was so happy ! I'm so proud of my project and of my friends that never gave up.
Here's a picture of VSL². Yeah, he has a name^^ in honor of his creators.
