During one interesting science lesson, Grade 8 students performed an experiment that simulated the effects of pollution on the world's oceans. As shared by Mr. Jeffrey Alvarez, MYP Science and TOK Teacher, the children are currently studying about how carbon dioxide, which is a gas that is released into the atmosphere through various ways by human processing (i.e. mining, agriculture, and electricity generation), is impacting our climate. Specifically, they were tasked to find a link (if any) between carbon dioxide and acidity. To investigate and find answers to this question, the students utilized dry ice, which is frozen carbon dioxide, to simulate pollution, as well as different amounts of it to test the effects. As Mr. Alvarez stated, "in oceans, when pollution (CO2) mixes with water it creates an acid. This is what students were creating and studying."
Through this powerful experiment, the students were able to immediately see the effects of carbon dioxide on the world's oceans, which was an eye-opener for most. They not only learned about the importance of sustainability and doing our part to be good citizens of the world, but they also had a fun time doing so with lots of cool bubbles, which as Mr. Alvarez mentioned, is "always a good thing!"
