Lessons of Caring for the Environment for Year 9 Science

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.

A Junior Genius joins a Year 10 Science Class!

Last Wednesday, one of our Year 10 Science classes was joined by Axel from Year 4.  Axel, a pocket rocket in his giant high school lab apron, joined in to help teach Year 10 about rates of reaction and what happens when you heat things up. Working with Tom they timed the reaction of sodium thiosulfate and hydrochloric acid at different temperatures. Axel joined in the wrap-up and helped discuss the conclusions.  

Bringing the junior school into the senior school was a brilliant experience and as Tom said, “he’s much better at drawing graphs than us.” As a successful experiment, we look forward to welcoming more junior school students visit to experience science and add their talents to our team.  Well done Axel!
