At Ravenswood School for Girls on Sydney’s north shore on a recent Friday, the playgrounds were full of girls who were not texting or even updating their social media status. A large group of year 10 girls was shrieking with delight over a skipping game where at least 12 jumped together. A group of year 11 students tried a new version of Twister. Other girls were playing the old-fashioned game of totem tennis. It’s part of a program called Look Up Lunchtime, devised by Kate Barbat, a teacher of personal development, health and physical and education.
