straws, tape, scissors, cylindrical container (like a soup can or jar), heavy items (like books)
In this activity, you will take on the role of a structural engineer. Structural engineers use shapes to add strength and stability to buildings roads, and a variety of products. Your mission is to create a powerful wrist cuff by using a repeating pattern of shapes. The cuffs have to be strong enough to support the weight of a stack of books.
Any cylindrical object that measures larger than most wrists can be used instead of a soup can. For example, the inside of the roll of tape can be used to shape the cuffs.
1. Asking questions (for science) and defining problems (for engineering) 2. Developing and using models 3. Planning and carrying out investigations 6. Constructing explanations (for science) and designing solutions (for engineering)
