GAIGE’S CLASS TEST RESULTS

• Purple group’s bridge held 56g. We believe it needed more supports to be stronger.
• Blue group’s overpass held 70g. We believe more bottom supports could have improved it.
• Orange group’s overpass held 91g. We believe filling in gaps helped it to hold plenty of weight.
• Yellow group’s overpass was the strongest holding 141g. We believe testing our bridge with various objects ensured it would hold plenty of weight.
