Building a bridge in San Francisco has to take into account the possibilites of earthquakes. This Science Buddies science project asks that you use different virtual bridge designs to withstand virtual earthquakes. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
