Fragile Foundations: Plankton, Microplastics and the Quest to Save Aquatic Biodiversity
Objectives of the project
Fragile Foundations: Plankton, Microplastics and the Quest to Save Aquatic Biodiversity aimed to help students investigate the presence of microplastics in the marine environment, especially on a local coastal beach and at the plankton level.
The project encouraged students to connect global plastic pollution with observations made in their own coastal area. By collecting samples, observing plankton and plastic particles under a microscope, and reflecting on the food chain, students developed a better understanding of how microplastics can affect marine organisms and aquatic ecosystems.
The project also aimed to strengthen students’ scientific approach, environmental awareness, and understanding of water protection, marine biodiversity, and human impact on the ocean.
Activities
Students carried out waste collection activities near the school and on Goaz Lagorn beach in Lannion, observing and collecting visible plastic waste and fishing-related debris such as ropes and filaments.
They collected sand samples from the beach and tested different sampling and analysis methods. The protocol evolved during the project, moving towards more precise sample collection using quadrats, flotation, sieving, and microscope observation.
Students also used plankton nets to collect samples over several days and observed them under a microscope. These activities helped them identify plastic waste in water samples and explore the relationship between microplastics and plankton.
The project also included discussions with parents, communication outside the school, classroom activities, artistic work inspired by plankton, and exhibitions to share the results with the wider school community.
Expected Outputs
The project produced sampling protocol sheets for waste collection, sand collection, and plankton net fishing.
It also created observation and sorting guides, classroom presentation materials, posters, and exhibition content that can be used for awareness-raising activities.
The project contributed to several subject areas, including Life and Earth Sciences, Physics and Chemistry, Mathematics, and Visual Arts. Students explored topics such as ocean pollution, plankton in food webs, water quality, plastic fragmentation, and the transformation of pollutants.
An important output was the development and improvement of scientific protocols that can be reused and adapted for future classes and educational activities.
Impact
The project involved 117 students in activities related to plankton and microplastics, including field trips, sample collection, laboratory observation, artistic representation, and water analysis.
Students developed practical scientific skills, including sampling, observation, filtration, sorting, and microscope use. They also strengthened their understanding of microplastics, plankton, water quality, and the impact of human activities on marine ecosystems.
The project helped students make a direct link between their local coastline and wider environmental issues. It also supported multidisciplinary learning by combining science, mathematics, art, and environmental education.
The results and resources will continue to support classroom activities, exhibitions, awareness-raising initiatives, and future work linked to the school’s Educational Marine Area.
