On Wednesday 27th March six primary 7 pupils were invited to take part in the STEM challenge run by SENTINUS. The Primary stem challenge is a hugely enjoyable problem solving challenge for teams of three pupils. The two Holy Trinity teams entered were up against some stiff competition from different primary schools across Belfast. Using basic technology materials, the pupils were required to design and build a solution in a set time. This year the children had to design a car that would carry a load down a ramp and travel across the assembly floor. Both teams did extremely well and represented themselves and the school with great distinction.
