During the last few weeks, in 4th grade of Primary students have been learning and exploring structures and machines as part of one of the subjects in IPC. To finish the unit, the 1st edition of “Invention Competition” has been held. The students had a few days to plan and develop “new inventions” to surprise us with. All the participants have shown a lot of interest, ingenuity and creativity, but only one has been the winner: Iker F. Without detracting from the others since the effort has been evident. Congratulations to all!
