Produced by the Take Our Daughters and Sons to Work Foundation and North Carolina State University, these guides introduce elementary and middle level students to the engineering design process and teach them to overcome obstacles through creativity and teamwork. Though the guides were created to use on Take Our Daughters and Sons to Work Day, teachers can also use the activities in the classroom. In the Level One NC State Challenge STEM Activity Guide (http://bit.ly/2aA8g3L), students complete team activities, such as constructing a castle with hula hoops and creating a human Rube Goldberg machine. In the Level Two NC State Challenge STEM Activity Guide (http://bit.ly/2alGDuW), students design an effective packaging system for a single potato chip and make ice cream. In the Level Three NC State Challenge STEM Activity Guide (http://bit.ly/2aA9ITY), students design a maze that a NanoBug can successfully navigate and build a rocket that can deliver the most air canisters (i.e., paper clips) to the International Space Station (i.e., the ceiling).
