Tech Challenge

Yesterday we did a Tech challenge.

The materials that we had to use was 20 pieces of ice block sticks to make a self supporting bridge with the span of 25 cm gap. That would hold a quarter filled water bottle with the weight of 500g.

The trick my group used was weave the sticks together to make the sticks stick together. The word that would describe it would be Tension.

Making the bridge was hard at first. My idea was to weave them together. Took my group awhile to listen. Near the end we were panicking because if we had maybe 2 more minutes then we could weave the last stick then the bridge would be done. When it was time to hop on the mat Mr Bernie gave us this long as talk. After that we moved on to our bridge and put on a empty water bottle. We were glad that it supported the weight then Mr bernie filled it quater way then one he placed it on the bridge. It stood stable for maybe a second then it broke 2 thirds the way and fell. But the pieces that fell were still in its shape. Luckily we won though.
