Students are structural engineers hired to rebuild a candy structure at a factory. The current structure is failing due to machine vibrations on the factory floor. Students will learn about vibrations, earthquakes, sound, and careers through the engineering design process, which guides them through the module. Students will build a toothpick and marshmallow structure that must withstand two different tests on a gelatin shake table. This kit contains enough materials for 10 groups. Access to curricula materials can be found at http://www.nicerc.org.
Materials in this kit include: nylon string, plastic eggs, marshmallows, rice, navy beans, cotton balls, paper clips, marbles, toothpicks, washers, string, aluminum baking pans, and Jell-O®.
WARNING: Choking Hazard. Small Parts. Not for children under 3 yrs.
