🏛️ Architects of the Future: Systems, Code and Ethics
An annual 8-mission plan for eighth grade, focusing on programming, aerospace engineering and the ethics of complex systems.
Main Objective of the Plan
To empower eighth grade students with the programming, data analysis, and engineering design skills needed to model complex systems and ethically debate the frontiers of technology.
STEM Disciplines and Skills

Technology: Disease propagation simulators (NetLogo, or simple in Scratch).
Engineering: Design of public health «interventions» (e.g., handwashing campaigns, ventilation systems).
Mathematics: Exponential growth (concept), statistics (analysis of «patient» data).
