Activity 01
Inquiry Circle: Layering the City
Students work in teams to design a new community center. They must use 'analog GIS' by drawing different data layers (transit lines, population density, flood zones) on clear plastic sheets and overlaying them to find the optimal location.
Analyze how different map projections influence our perception of world power.
Facilitation TipDuring Collaborative Investigation: Layering the City, circulate to ask guiding questions that push students to articulate how projection choice affects their analysis of urban layers.
What to look forProvide students with images of three different world maps (e.g., Mercator, Gall-Peters, Robinson). Ask them to identify one key characteristic of each map projection and one type of distortion that is evident.

Activity 02
Think-Pair-Share: The Ethics of Tracking
Students read a short prompt about a company using GPS data to track employee movements. They reflect individually on the privacy implications, discuss their thoughts with a partner, and then share a proposed 'Digital Bill of Rights' with the class.
Differentiate between various map projections and their appropriate uses.
Facilitation TipDuring Think-Pair-Share: The Ethics of Tracking, assign specific roles (e.g., analyst, advocate, data subject) to ensure balanced perspectives in discussions.
What to look forPose the question: 'If you were creating a map to advocate for global climate action, which type of map projection would you choose and why?' Facilitate a class discussion where students justify their choices based on projection properties and potential audience perception.

Activity 03
Simulation Game: Disaster Response Command Center
The class is divided into response teams (fire, medical, logistics) following a simulated hurricane. The teacher provides 'remote sensing' updates (satellite photos of damage), and teams must use the data to prioritize where to send resources in real time.
Evaluate the ethical implications of map distortion in representing global data.
Facilitation TipDuring Simulation: Disaster Response Command Center, provide students with time constraints and limited resources to mimic real-world urgency in their decision-making.
What to look forOn an index card, have students write down the name of one map projection and explain in 1-2 sentences why it might be chosen for a specific purpose, such as displaying population density or planning flight paths.

Generate Complete Lesson→A few notes on teaching this unit
Teach this topic by starting with student-generated questions about why maps look different, then use hands-on comparisons of projections to reveal hidden distortions. Avoid lecturing on projection families; instead, let students discover trade-offs through structured investigation. Research shows that when students physically manipulate projections (e.g., stretching, resizing), they better grasp how distortion arises from the transformation process. Use the language of 'trade-offs' and 'purpose' repeatedly to build conceptual clarity.
Successful learning looks like students explaining why certain projections distort area or shape, selecting appropriate projections for given tasks, and connecting their choices to real-world consequences such as policy decisions or resource allocation. They should articulate trade-offs between different projections rather than simply identifying them.
Watch Out for These Misconceptions
During Collaborative Investigation: Layering the City, watch for students describing GIS as just 'a digital map.'
Redirect them to examine the data layers they are combining (e.g., flood zones, income data) and ask how those layers enable analysis rather than navigation.
During Simulation: Disaster Response Command Center, watch for students conflating GPS with satellite imagery.
Pause the simulation to have students list the roles of GPS (location tracking) versus remote sensing (imagery collection) using the tools provided in the simulation.
