Children will compete to build a robot to solve a series of missions on an obstacle course related to an environmental topic. They will also have to solve a theoretical task researching a topic and preparing and sharing a presentation.
The children will work in teams with experts from universities, consultant companies and industry to produce an implementation plan for their research projects.
The winning project "will be implemented in real-life," said Lego vice president Lisbeth Valther Pallesen, adding that she hoped the winners could present their idea at the UN climate summit in Copenhagen in December.
Lego spokesman Flemming Gammelgaard said the May 2-3 event was a "competition of creativity and team spirit" aimed at fostering children's interest in research.
Danish Crown Prince Frederik will on Sunday visit the Children's Climate Call, described as the world's biggest science and technology tournament for children.
