Leaning Tower of Pasta
Using 20 unbroken spaghetti noodles and 30 marshmallows, student teams constructed the tallest free-standing structure.This challenge helped them experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments helped them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension.
Engineering Connection
Engineers consider tension and compression forces when designing a building or structure and choosing the materials to build it. All structures must be able to handle the forces that act upon them so they will not fail and injure people. Like all structures, the foundation, frame, and joints of a skyscraper must be able to withstand enormous tension and compression forces from the weight of its own materials, the load of people, and the impact of natural forces.
