In this Design Challenge, families and friends work together to design the tallest structure that they can, using only the materials provided.

Students design a device to rescue a trapped pet using what they know about form and function in nature.  
Detailed explanation of body structure and their functions guide the design of the device used to rescue the pet. Also included are suggested sources for further exploration at a variety of levels.
A three-tiered design process is utilized - conceptualization, constructing and testing, and acquiring knowledge.
The needed materials include common readily available items.
Discussion and reflection questions provide support and alternative ideas for the design of the device.
