They call this generation the Mars generation… these children could be among the future explorers and Engineers that will fulfill that interplanetary destiny. Yet there will also be some that would like to improve life here on earth. This will be an opportunity for students to work in small teams and use their design skills to build a model of choice – 1) Lego Space Race or 2) Lego Treehouse. We will focus on the United Nations Goal 9: Industry, Innovation, and Infrastructure, and United Nations Goal 11, Sustainable Cities and Communities. Participants will be learning about the fundamentals of construction engineering and how to apply them structurally to design stable buildings. There will be specific design criteria, for example that it must have a mechanical device to move (or launch) a load 30 cm, or have a tree-like structure (elevated base) and other functions like a slide or swing or tear-away roof.
