Youngsters were getting to grips with structures and physics in a special challenge.
Key Stage 2 pupils at Exton and Greetham Primary School were put to the test in a K’NEX Classroom Challenge.
The children were separated in teams of two and had an hour to put together a crane that would carry the weight of a beanbag.
The challenge was part of Stemnet, a national initiative that aims to inspire young people in science, technology, engineering and mathematics.
Headteacher Kathy Whitehead said: “The children loved the challenge and they were all quite competitive.
“They came up with lots of different strategies and ways of making their cranes and it was great to see.
“They really enjoyed it.”
