We at Killorglin Community College are very proud of our history in the BT Young Scientist Competition, this tradition continued this year with the project “Sagassum Muticum, Is it a threat to Biodiversity”. The project was carried out by two 2nd year science students Holly Brown and Harry Hilliard. The project looked at the impact of this invasive seaweed species on Biodiversity and the methods that could be used to tackle it spread.
