Pupils from Denend Primary School are revving up ahead of the F1 in Schools Competition next week.
Two teams of P7 pupils from the Cardenden school will take part in the challenge at Adam Smith College in Kirkcaldy on Tuesday - the only primary school in the whole of Scotland to take part.
The competition aims to raise interest in a career in engineering, with an array of different areas for the 12 pupils to tackle.
‘Denend Designers’ and ‘Sonic Waves’ had to design, construct and race a car, come up with eye-catching logos, as well as raise sponsorship and manage a budget by themselves.
They also had the tricky task of inventing their own software.
Head teacher Lorna Palmer said she was “thrilled” with the hard work the pupils have put in.
“It’s been a fantastic effort,” she said.
“It’s been very exciting. It’s not just teaching them practical skills but life skills also which will stand them in good stead for the future.”
The teams have been lead by teachers Charlie Richards and Catherine Sinclair, who said it had been a massive challenge.
“The children have given up a lot of their own time, such as lunch and dinner breaks and there’s still a lot of work to do before next week,” said Catherine.
“They had to prepare a 20 page booklet and have to give a five minute presentation, so there’s been lots of different elements to it, which has been extremely challenging for them, but also it’s been a lot of fun.”
Stem ambassador Stewart Sutherland has been on hand to help and Catherine said: “We couldn’t have done it without him!
“We’ve also had a lot of help and support from parents and from Glenrothes High School.”
The children will spend all day at the college on Tuesday and hope to progress to the Scottish finals.
Team manager, 11-year-old Tristen Brannan, said she was “nervous” ahead of the big day.
She said: “It’s been hard work but we’ve picked up lots of skills and it’s been really enjoyable.”
