ENGINEERING: BRIDGE INVESTIGATION

We measured Slinky's before and after tension was applied.  We discussed how compression makes things smaller and tension makes things longer and the effects these forces have on bridges. 
We had a relay race to see which team could compress sponges to put the most water in the buckets. 
The children create a beam with an "accordion" deck.  A deck that has triangles between the decks.  The children place objects on this bridge to test its strength.  The children then record the objects the bridge will hold.  The children use a graph to compare the strengths of all three bridges: BEAM, ARCH and ACCORDIAN
The children make "cable" for the suspension bridge by twisting together 3 small strings into one large cable.
