In medicine, a prosthesis (plural: prostheses; from Ancient Greek prosthesis, addition, application, attachment) is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or congenital conditions.

Have students brainstorm ways to make the prosthetic arm move. A bonus challenge is to create a prosthetic arm and/or hand that can pick up an object.
