Geographic Information Systems (GIS) & GPSActivities & Teaching Strategies
Active learning works for this topic because students need to visualize how data layers interact to solve real-world problems. Moving from abstract concepts to hands-on mapping tasks builds spatial reasoning skills and career-relevant technical literacy that passive delivery cannot match.
Learning Objectives
- 1Analyze how GIS layers, such as population density and road networks, help urban planners identify optimal locations for new public services.
- 2Evaluate the ethical considerations of using GPS data for public safety versus individual privacy in a specific city scenario.
- 3Create a simple map using a GIS platform that visualizes the distribution of a chosen geographic feature (e.g., parks, fast-food restaurants) within their local community.
- 4Explain the fundamental process by which GPS satellites determine a receiver's location on Earth.
- 5Compare the capabilities of GIS and traditional map-making in representing complex geographic information.

Ready-to-Use Activities
Inquiry Circle: Map the Problem
Using ArcGIS Online (free for K-12), small groups layer publicly available data to map a local issue such as food access deserts and grocery store locations, or park coverage by neighborhood. Each group presents their map and explains what the spatial pattern reveals about the problem.
Prepare & details
Explain how GIS technology assists urban planners in making informed decisions.
Facilitation Tip: During Collaborative Investigation, assign each group a different data layer to research before combining them to highlight how GIS integrates multiple information types.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Think-Pair-Share: Is Location Data Sharing Safe?
Students read a short scenario about a social media app that tracks users' locations in the background. Individually they write about the benefits and risks, then pairs discuss and the class maps responses on a shared pro-con chart to analyze the trade-offs.
Prepare & details
Analyze the ethical implications of using GPS and location tracking data.
Facilitation Tip: In the Think-Pair-Share activity, provide students with two different app permission screenshots to spark discussion about location data sharing.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Gallery Walk: GIS in Action
Post six case study cards showing how GIS has been used in real-world scenarios: wildfire response mapping, COVID-19 case tracking, hurricane evacuation routing, urban heat island analysis, traffic planning, and disease vector mapping. Students annotate each with a question and an insight before groups discuss common themes.
Prepare & details
Predict how advancements in spatial technology might transform future geographic studies.
Facilitation Tip: For the Gallery Walk, display GIS project examples at different complexity levels so students can identify patterns in how professionals use spatial analysis.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Individual Reflection: Your Digital Footprint Map
Students list five apps on their phone (or a hypothetical phone) that use location data. For each, they note what data is collected, who receives it, and whether they think the trade-off is worth it. A small group share-out follows, culminating in a class discussion about digital consent.
Prepare & details
Explain how GIS technology assists urban planners in making informed decisions.
Facilitation Tip: When students create their Digital Footprint Map, provide a checklist of data sources they might include to guide their reflection.
Setup: Groups at tables with access to research materials
Materials: Problem scenario document, KWL chart or inquiry framework, Resource library, Solution presentation template
Teaching This Topic
Teachers should approach this topic by starting with students' existing familiarity with GPS apps before introducing GIS as a professional tool for layered analysis. Avoid teaching GIS as a software tutorial; instead, focus on spatial questions and data relationships. Research shows students learn spatial concepts best through inquiry-based tasks that require them to make and test predictions about geographic patterns.
What to Expect
Successful learning looks like students using GIS tools to analyze spatial relationships, explaining how location data informs decisions, and evaluating privacy implications of technology use. Students should move from recognizing GIS as a tool to applying it for problem-solving and ethical reasoning.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Collaborative Investigation, watch for students treating the final map as just a digital version of Google Maps rather than a tool for analyzing relationships.
What to Teach Instead
Use the group's research phase to emphasize that each layer represents a different type of data that must be interpreted together, not just viewed sequentially like a navigation app.
Common MisconceptionDuring Think-Pair-Share, watch for students assuming that location data is only collected when apps are actively in use.
What to Teach Instead
Have pairs examine their own devices' location settings screenshots to identify background data collection and system-level tracking they may not have noticed.
Common MisconceptionDuring Gallery Walk, watch for students conflating GPS satellite signals with the analytical capabilities of GIS software.
What to Teach Instead
Ask students to identify in each display where GPS provides coordinates versus where GIS transforms those coordinates into meaningful spatial analysis.
Assessment Ideas
After Collaborative Investigation, have each group submit a one-paragraph reflection explaining which data layer they found most surprising and how combining layers changed their understanding of the problem.
During Gallery Walk, circulate and ask each student to explain one way GIS tools help professionals make decisions that GPS alone cannot.
After Think-Pair-Share, use the privacy concerns raised to facilitate a class vote on which location data permissions are most concerning, then have students justify their choices with examples from the activity.
Extensions & Scaffolding
- Challenge students to design a GIS story map explaining a local environmental issue using at least five data layers.
- For students who struggle with data interpretation, provide a partially completed GIS project with missing data layers for them to analyze and complete.
- Offer deeper exploration by connecting students with local GIS professionals for a virtual Q&A about how they use spatial analysis in their careers.
Key Vocabulary
| Geographic Information System (GIS) | A computer system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. It allows for the layering of different types of spatial information. |
| Global Positioning System (GPS) | A satellite-based navigation system that provides location and time information anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. |
| Spatial Data | Information that describes the location and shape of geographic features and the relationships among them. This data can be represented as points, lines, or polygons. |
| Geocoding | The process of converting addresses or place names into geographic coordinates (latitude and longitude) that can be used on a map. This is a common input method for GIS. |
| Vector Data | Geographic features represented as points, lines, or polygons, each with a specific location and attribute information. Roads are typically represented as lines, and buildings as polygons. |
