Recently in P.5-P.7 we had a go of our new K’Nex kits we just got as part of Maths Week.  We had to try and make a windmill using gears and it was hard at first. We all came across 1 or 2 problems but we never gave up and everyone managed to finish there windmill and they all look really good.  We saw how different gears can change the speeds or moving parts.
