Wellington College in Crowthorne hosted four schools as part of the initiative, which sees schools across the country going head to head testing their science, technology, engineering and maths (STEM) skills.
Teams of six Year Eight students had to solve an engineering challenge, thinking through design, build and materials.
They were set the task of building a rocket using items available, which would then be launched.
Sue Parker, Wellington College’s independent state school partnership co-ordinator, said: “They all went up but some went higher than others! I was in charge of the ‘shop’ so they were haggling with me over the price of materials.
“It went really well and there was a great atmosphere.”
Kings International College won the day, and took home a plaque and vouchers.
Youngsters from Eagle House School in Sandhurst, Collingwood College and Kings, both in Camberley, and Wellington Academy, Wiltshire, took part in The Institution of Engineering and Technology’s (IET) Faraday Challenge Day, on Tuesday last week.
