Today is the big day for a group of Year 7 and 8 girls from Hunterville School.
The students are competing in the finals of the Epro8 Challenge in Palmerston North.
EPro8 means "engineer, problem solve, and innovate".
The Hunterville School all-girls team took out first and second place in the EPro8 semi-finals in Feilding last month.
In the competition, teams of four students are given a series of challenges to complete over a two-and-a-half hour period. A typical challenge was building a 1.8m tower and hanging a swing to hold a 2kg weight. The weight would have to swing nine to 10 times in 11 seconds, to create an electronically controlled waving arm. Another was building a motorised moon buggy.
