A SUPER Strong STEM Activity: Super Cuffs by @TechbridgeGirls

Required materials:

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.

NGSS alignment:

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)
