Family participatory science (forms of scientific knowledge production in which non-scientific-professional actors actively and deliberately participate).
After some cell sieving in the lake waters, we will observe with paper microscopes the plankton and phytoplankton that are found there. We will also have the opportunity to track down the presence of microplastic pollution. Thanks to the use of ultra-flat and easy-to-use microscopes, everyone will have the opportunity to get their hands dirty.

From 7 years old. Reservation and payment required at the Maison du Patrimoine et de l'Environnement de Chamrousse.

Meeting point directly at the Achard lake (information on the access itinerary Chamrousse 1750 - Achard lake below in suggestion). Bring mountain shoes, sunglasses, a hat, rain gear, a fleece in case of cool weather.

Please register with the Environment and heritage centre the day before at the latest.
