Children and staff at Manor Primary School, Uckfield, are being encouraged to take part in the Digital Sunset challenge.
This asks them all to turn off their tech for an hour before bed and there will be extra house points for children who can prove they have done it for a whole week.
The challenge was issued when the school took part in the global Safer Internet Day on Tuesday.
The event promoted the safe and responsible use of technology, and highlighted the kind of issues that can concern young people as a result of an over-reliance on their tech, ranging from lack of sleep to bullying.
The day was coordinated in the UK by the UK Safer Internet Centre and revolved around the theme ‘Create, Connect and Share Respect: A better internet starts with you’.
More than 100 countries took part and hundreds of organisations across the Uk were involved too in a bid to help create a better internet.
A range of activities – including age appropriate assemblies led by their own digital leaders – were laid on at Manor and more than 400 young people parents, and staff, took part in them.
Beccie Rawlins, computing coordinator at Manor said: “This is a great opportunity for our digital leaders to promote awareness of online safety.
“The children have been working hard to create assemblies and activities that support the Safer Internet Day message.
“In our assemblies today the digital leaders challenged the children (and staff) to take part in a Digital Sunset which means turning off all our tech for an hour before bedtime.
“The digital leaders are also planning an online safety awareness evening for parents next term.”
