Introduction to Maps and Globes

Active learning works for this topic because students need to move between three-dimensional globes and two-dimensional maps to truly grasp the trade-offs of projection. When students physically manipulate models, they notice distortions that stay invisible on screens. These hands-on exercises build spatial reasoning skills that are essential for geography, navigation, and environmental science.

Activity 01

• Project-Based Learning
• 35 min · Pairs

Globe-Map Overlay Challenge

Pairs receive a globe and printed maps of Mercator, Peters, and Azimuthal projections. They trace Ireland and Africa on each map, then overlay transparencies on the globe to measure distortions in size and shape. Groups share measurements and vote on best projection for Irish coastal studies.

Evaluate the comparative advantages and systematic distortions of major map projections , including Mercator, Peters Equal-Area, and Azimuthal projections , and assess the ethical and practical implications of projection choice for the representation of global development patterns and geopolitical relationships.

Facilitation Tip

During the Globe-Map Overlay Challenge, have students trace the same route on both the globe and a Mercator map to measure how much distances and shapes shift.

What to look for

Provide students with three world maps, each using a different projection (Mercator, Peters, Azimuthal). Ask them to identify which projection is which and write one sentence explaining a specific advantage of one projection for a particular purpose, like navigation or comparing continent sizes.

Activity 02

• Project-Based Learning
• 25 min · Small Groups

Orange Peel Projection Demo

Small groups peel an orange into eight segments, flatten them on paper, and tape into a map. They label segments as continents and note shape/area changes. Relate to real projections and discuss implications for global data representation.

Analyse how remote sensing technologies , including multispectral satellite imagery, LiDAR terrain modelling, and UAV photogrammetric surveys , are transforming spatial data acquisition for environmental monitoring, coastal hazard assessment, and urban growth analysis in Ireland.

Facilitation Tip

For the Orange Peel Projection Demo, remind students to press gently when flattening the peel to avoid tearing, so distortion remains visible but manageable.

What to look for

Pose the question: 'Imagine you are presenting data on global poverty to policymakers. Which map projection would you choose and why? Consider the potential impact of your choice on how the audience perceives the scale of the problem in different regions.' Facilitate a class discussion on the ethical implications.

Activity 03

• Project-Based Learning
• 40 min · Small Groups

Remote Sensing Map Match

Small groups get satellite images, LiDAR terrain models, and corresponding maps. They identify features like Irish cliffs or urban sprawl, align layers digitally or with paper, and note how projections affect hazard assessment accuracy.

Design a geographical fieldwork investigation specifying a testable hypothesis, an appropriate sampling strategy, and a statistical analysis framework that meets the methodological requirements of the Leaving Certificate Geography fieldwork report.

Facilitation Tip

When running Remote Sensing Map Match, provide a printed key of land cover types (e.g., forest, urban, water) to help students label the satellite image accurately.

What to look for

Show students a multispectral satellite image of an Irish landscape (e.g., a coastline or agricultural area). Ask them to identify one specific geographical feature or change that can be observed and explain how remote sensing technology made this observation possible.

Fieldwork Hypothesis Workshop

Whole class brainstorms a hypothesis on local landscape change, like Dublin urban growth. In small groups, they design sampling strategies and basic stats tests, then present for peer feedback aligned to Leaving Cert criteria.

Evaluate the comparative advantages and systematic distortions of major map projections , including Mercator, Peters Equal-Area, and Azimuthal projections , and assess the ethical and practical implications of projection choice for the representation of global development patterns and geopolitical relationships.

A few notes on teaching this unit

Experienced teachers approach this topic by starting with globes to establish Earth’s spherical shape, then introducing maps as tools that trade accuracy for utility. They avoid overwhelming students with too many projections at once and instead focus on one distortion at a time. Research shows that concrete comparisons—like overlaying routes or tracing coastlines—help students internalize why projection choices matter in real-world contexts.

By the end of these activities, students will confidently explain why no single map is perfect, compare projection strengths for specific tasks, and decide which representation best serves a given purpose. They will also connect Ireland’s position to global patterns and justify their choices with evidence from their work.

Watch Out for These Misconceptions

• During the Globe-Map Overlay Challenge, watch for students assuming that all flat maps show Earth with equal accuracy.

  Use the tracing step in the activity to measure how Mercator inflates Greenland compared to Peters. Ask students to calculate the difference in area and discuss which projection would be better for comparing country sizes.

• During the Orange Peel Projection Demo, watch for students believing Mercator projection is the most accurate overall.

  Have students flatten their peel and compare the distortion of shapes near the poles to the equator. Ask them to identify which regions stretch and which shrink, then connect this to Mercator’s limitations.

• During the Remote Sensing Map Match, watch for students thinking globes eliminate the need for maps entirely.

  After matching features, ask students to list details they can see on the satellite image (e.g., roads, fields) that are not visible on a globe. Use this to highlight how maps provide local detail globes cannot.
