Metz. Nearly 1,200 students at the Science Festival at the Lycée Louis-Vincent

How does surface tension or magnetic field work? What effects does liquid nitrogen produce? To get answers to these questions, just go to the Lycée Louis-Vincent on Saturday 15 October, for the Science Festival.

This week, hundreds of schoolchildren, from primary to second grade, have already taken part in the exercise. “We are in attendance about 1,200 pupils,” explains Laurette Chaleix, Director of Training at Lycée Louis-Vincent.

Adapt to the audience

BTS chemistry students wore the teacher’s blouse. They animate the different stands, such as Laura, Amanda, and Candice. They explain to visitors the phenomenon of surface tension, which allows a CD to float on the surface of water, for example.

“It’s the first time we’ve given a presentation in front of an audience,” says Laura. The secret of a successful workshop? “You have to adapt to the audience,” she explains. “It’s easier to explain to the little ones,” emphasizes Axel, Maxins and Lucas, who give a workshop on magnetism. “There are fewer technical terms,” ​​Axel says.

“Don’t disgrace them with knowledge”

In front of the surface tension platform, CM1 students from Cressot School in Montigny-lès-Metz quietly listened to the BTS students’ presentation, carefully taking notes. Meanwhile, another part of the class heard a presentation on liquid nitrogen. The battery was immersed in liquid nitrogen. “Are you going to explode?” Then a junior asked. He was told: “No!”

Laurette Chaleix explains “It’s for all levels. We try not to disgust them with science, we really lack scientists in France. And not because you do a general course you can’t become an engineer!”

Free entry on Saturday 15 October until 6 pm. Possibility to park in the yard.
