Thursday, November 19, students in the class Mr. Thouin went to the Science Festival at the Parc des Expositions de Caen, to conduct scientific experiments.
We participated in 3 workshops:
The inventors of wreckage, Seeds scientist at the small Lab'eau Lavoisier and Evolution and revolution in the construction industry.

1-Inventors wreck
Arriving at the studio, we found a wreck and displays. First, a facilitator showed us all kinds of spacesuits and equipment used to excavate underwater.
We have been in the same situation as archaeologists. For the wreck, there were two main questions to be answered: Where did the boat and when? With amphorae, works of art and coins found in the wreckage, we know that the boat sank in the 1st century BC, he passed by Rome, Carthage and stayed in Greece.

2-seed scientist at the small Lab'eau Lavoisier
We experimented on the skin of water. Here are two:
An initial experience:
We used a cabbage leaf. We deposited a drop of water that moved remaining under its shape perfectly round. Then we lightly scraped the leaves of cabbage with your hands. The water that remains in the form of a drop but it was scattered.
Editor's Note: The skin of the water was broken by impurities that are has on hand and can no longer keep the water in the form of a drop.
A second:
We made a boat with a sheet of plastic, paper, toothpicks and tape. There lay the boat in a container filled with water. When placing a drop of oil on the back of the boat, it starts and joins the board of the vessel at full speed.
Editor's Note: The oil off the skin of the water causing it to break into the boat.

3-Evolution and revolution in the field of construction
We first learned about all kinds of bridges. Facilitator then explained the journey of water through a mock city. We observed how a houseboat. Finally, we watched a short film about the world's tallest buildings, from the pyramids to the existing skyscrapers.
