In Science this week, Year 9 have been concerning themselves with the environmental impact of ocean acidification. They have learned about the impacts of acid rain and the increased acidity of lakes and oceans as excess carbon dioxide is absorbed from the atmosphere.
Class 9B carried out investigations to assess the loss of mass from different shells when they are exposed to acid. The shells effervesced and were visibly more fragile after ten minutes. Weighing them revealed a 30-50% loss in mass. The results were a beautiful eye-opener to the importance of caring for our environment.
