The private school is launching a new course in the next term as a way to encourage children to think critically about the information they receive online.
Aristotle’s teachings about truth are to feature on the course, which will be overseen by Leak Hamblett, the school's deputy headmistress.
Ms Hamblett, a philosophy teacher, hopes that the children will learn how to differentiate between "what is real and what is true".
She told the UK's Telegraph newspaper that : "I want to teach them to go looking at resources, looking at where your source comes from, are they respectable?
"If you're going to read something check it out on a few different platforms, don't necessarily think it's true because it's come through social media.We have a responsibility as teachers to make children more savvy about what they hear and read."
An earlier report published in 2017 warned that children and young people in England do not have the critical literacy skills needed to identify fake news.
