As part of the fifth grade unit on Structures, Mrs. Rhodes' science classes built bridges as a take-home project.
Bridges are special structures because their frameworks are exposed.
They are the perfect combination of the principles that a unit on structures explores. Tension, compression, balance, and materials are important to the design and the amount of weight that a structure can withstand. After several in-class science experiments that dealt with these four things, the students were given guidelines for building their own bridges. The pictures that follow are the results of a great deal of hard work. My name is Sandra.
