K’nex Challenge 15.06.22

Today, we enjoyed taking part in the STEM K’nex Challenge. We had to design and make a bridge to span a river which could lift, slide or move to allow boats to pass underneath. Our bridge had to support a 50g weight. It was much trickier than we thought! Well done to Benji and Elizabeth for being our class winners; a photograph of their model will now be entered into the Hertfordshire competition.
