A photograph taken using the latest technology has been added to a time capsule marking a school’s 90th birthday.

Pupils and staff at Whitehill Primary School, Gravesend, gathered on the field to form the number 90 before a drone was sent soaring into the air to capture the moment.

The picture was then turned into commemorative bookmarks and postcards, with some put in a time capsule that was buried in the grounds.

Teachers and pupils were also joined by 70 Old Whitehillians – former staff and pupils – for an art exhibition put together by pupils and to plant a memorial tree and the capsule.

Each class created artwork to represent the different decades the school has been open.

Children explored fashion over the years and created pictures based on the work of Jackson Pollock, the American painter who was a leading figure in the art world during the 1920s when the school opened.

The guests, aged between 30 and 90, were also treated to tea and biscuits and a display of memorabilia dating back to the 1930s.

The Mayor and Mayoress of Gravesham, Cllr Howard Craske and his wife Veronica, were joined by a pupil from each class to plant the silver birch and capsule in front of the main building.

The pupils, ranging in age from four to 11, piled the soil on top of the capsule.

It includes class pictures of present children, some items of uniform, a contact book, a newspaper, sports day medals, Ofsted reports, exercise books and a school prospectus as well as the anniversary postcards and bookmarks.

On the day the children were treated to a piece of cake in the classroom.

The primary school has 750 pupils, including a nursery for three to four year olds.

It has always taught both boys and girls, and started as a junior school in 1927. It had 315 pupils by 1928.

An infant school was added in January 1932.

Head teacher Malcolm Moaby said: “I am proud to be part of the history of a school that has served the local community for 90 years.”
