Biological Engineering

Overview

Following the steps of the engineering design process and acting as robotics engineer, student teams will use drinking straws to design and build a robotic hand. This robotic hand will mimic the way human fingers work: tendons bend the fingers while the muscles in the forearm control the action.

NGSS Standards

  • HS-LS1-2 Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

NGSS Disciplinary Core Ideas

  • HS.LS1A.b Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.
