Entry Events
Events that will be used to introduce the project to studentsThe 2075 Black Box
Students discover a 'black box' from a future city that collapsed due to resource depletion. Inside are encrypted data files (math problems), 3D artifacts of extinct species, and a desperate audio plea for a new design paradigm to save their timeline.The Billionaire’s Dilemma
A charismatic (simulated) billionaire offers the class $1 billion to design a city, but with a catch: for every 1% growth in GDP, they must prove a 1% increase in local biodiversity. Students must use technology and data to pitch their first 'Green Growth' prototype to stay in the running for the contract.The Workspace Congestion Crisis
Students are given 15 minutes to 'build' a business using blocks, but for every profit milestone, they must add 'waste' blocks that take up floor space. They quickly realize that without a circular system, their growth literally traps them, sparking a debate on how to turn waste into resource.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.The 'Cycle of Life' System Blueprint
Before coding, students must understand the math and science of a circular economy. In this activity, students compare a 'Linear City' (Take-Make-Waste) to a 'Circular City' (Reduce-Reuse-Recycle). They will calculate resource consumption rates and waste generation percentages to create a mathematical 'Resource Flow' diagram that serves as the foundation for their game mechanics.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'System Blueprint' infographic that includes calculated ratios of waste-to-resource conversion and a visual flow of materials within their proposed city.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.Math.Content.7.RP.A.3 (using proportional relationships to solve ratio and percent problems) and NGSS MS-ESS3-3 (applying scientific principles to minimize human impact). Students must use math to model the environmental shift from linear to circular systems.Algorithm Architects: Mapping the City Brain
Students will design the 'brain' of their Eco-Tycoon game. They will create logical pathways that determine how the game responds to player choices. For example: 'IF player builds a factory, THEN GDP increases by 5% AND Biodiversity decreases by 2% UNLESS a Carbon Filter is researched.' This scaffolding ensures students understand the cause-and-effect relationships in ecosystem management.Steps

What students will submit as the final product of the activityA comprehensive 'Logic Flowchart' or pseudocode document that maps out the primary gameplay loop and the environmental feedback systems.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with CSTA 2-AP-10 (using flowcharts and pseudocode to address complex problems as algorithms). It requires students to translate environmental interactions into logical sequences for game development.The Data Dashboard & Species Catalog
In this activity, students shift to the visual and user-experience (UX) side of the project. They will design the 'Biodiversity Dashboard'—the part of the game screen that tells the player how healthy their ecosystem is. They will also create 'Species Sprites' that represent the biodiversity metrics in the game, ensuring that the visual art changes based on the data (e.g., plants wilting if waste is high).Steps

How this activity aligns with the learning objectives & standardsThis activity aligns with ISTE 1.6.b (creating original works or repurposing digital resources) and NGSS MS-LS2-5 (evaluating design solutions for maintaining biodiversity). It focuses on the visual communication of scientific data.The Eco-Tycoon Engine Build
Students integrate their mathematical models, logical flowcharts, and visual assets into a functional game prototype (using tools like Scratch, MakeCode, or a paper-based simulation). They must demonstrate that their game accurately models the 'Circular City' goals: as the player implements circular strategies, the game's math should show a stabilizing effect on biodiversity despite economic growth.Steps
