Structure: Bridges
To begin their new unit on bridges, the children explored a beam and arch bridge, and their uses in the real world. They looked at how each type of bridge could be strengthened and supported, such as by laminating or corrugating the beam. We then tested these designs out by loading them up with weights.
As a continuation of our bridge unit, the children looked at a third bridge: the truss bridge. Using spaghetti and masking tape, the children made a series of triangles and beams, building up to testing the strength of their creations by loading them up with weights.
