Parfois, méfie-toi de l'eau qui dort

Lucas gets in the car with his dad to drive to the mountains. Very quickly, the curves make him feel sick. Dad suggests to Lucas to roll down his window to get some fresh air. Woofy also looks bad. Lucas rolls down his window and puts its nose in the wind. A bus arrives on the narrow road. It comes so close to the car that it tears…

On the platform in the subway, Lucas gets too close to the edge and almost falls on the rails. Fortunately, Célestin is watching over him: marks are drawn on the ground, he must respect them and stay away from the edge.

On their way home by train, Lucas, Emma and Victor are hanging out. When they realize that the teacher and their friends are already on the platform, they decide to join them by the shortest route: by crossing the train tracks. Fortunately, Célestin intervenes and shows them the danger.

Lucas, Thomas and Brice are in the backyard with scooters, skates and skateboards, but the gravel doesn't roll well, and the park is occupied by grown-ups. Brice has the idea to use the street, the bike path, the stairs of his building and the sloping street as a playground. But cyclists and pedestrians don't agree and there…

Lucas and Thomas are skateboarding in the park, accompanied by Emma who doesn't know how to skateboard. After a while, she gets bored and wants to try. Thomas lends her his skateboard and equipment and Emma begins her first lesson. In an attempt to keep up with Lucas, she goes downhill before she masters the technique and has a…

Lucas meets up with his friends to go rollerblading. The equipment is annoying, and it makes him look like a baby, so despite Emma's advice, he doesn't wear it. When everyone falls, those who are not protected are the most injured and can no longer play.

Lucas and his friends are rollerblading in a designated area. To impress Emma, and under the pretext that sidewalks are for everyone, Victor jumps on benches and passes between the pedestrians. Until he skates backwards and hits a passerby, spilling her bag of groceries. Célestin reminds them that sidewalks are primarily for…

Lucas and Thomas are riding their bikes in the garden. Lucas lets his bike fall on the ground without caring about it. Célestin and Thomas end up wondering why he takes so little care of his things. When questioned, Lucas finally admits that it's a good idea to take care of his things!

In the mountains, Emma and Lucas are riding their bikes, having promised Mom they would be home for dinner. The weather is nice and they ride to the sheepfold. They are surprised by a storm. Lucas asks the shepherd to warn his mother and realizes that before going for a ride, there are several things to consider.

It is a very warm day. While waiting to go to the pool, the children run water in the bathtub. Célestin reminds them that in a heat wave, they should not waste water: it should firstly be used for drinking and washing. And one must not forget to turn off the taps.

Lucas and his friends go for a walk in the mountains. Hélène recommends drinking while walking, without waiting to be thirsty. Seeing a waterfall gushing out of the rock, the children marvel at how beautiful the water is. Encouraged by Celestin, Victor ends up drinking this spring water instead of a soda. The walk ends with a swim in…

C'est amusant d'arroser le jardin, surtout quand il fait très chaud! Mais à peine arrosées, les plantes sont déjà sèches, et en piteux état. Célestin leur explique que lorsque le soleil est haut dans le ciel, l'eau s'évapore très vite, et les plantes brûlent. Arroser, c'est bien, mais le soir ou le matin,…

Impossible to swim today because the beach is invaded by plastic bags. But where do they come from? Célestin explains: all these bags that people take while shopping and then throw away, without much regard for the environment, will remain there for thousands of years. The children are horrified. What can we do to stop it? Take a…

Lucas is shopping for the new school year. He meets Thomas who has chosen notebooks made of recycled paper. At first skeptical, Lucas quickly understands that cutting down beautiful trees is contributing to deforestation. It is also contributing to the disappearance of certain animals. At school, Lucas and Thomas will be proud to show…
