Using Google Earth Timelapse to Explore Environmental Change (Years 5–10 Geography)

Introduction

Google Earth Timelapse is a powerful, free tool that visualises how landscapes have changed over the past several decades. Using satellite imagery from 1984 to the present, students can observe urban expansion, deforestation, coastal erosion, agricultural development and environmental restoration. This resource is ideal for Years 5–10 Geography and supports students in understanding human–environment interactions, long‑term change and sustainability. Because it’s browser‑based and requires no login, it’s accessible for all classrooms.

How to Use It in the Classroom

Teachers can guide students to explore locations in Australia or around the world to identify patterns of change. Students can compare before‑and‑after imagery, analyse causes and consequences, and propose strategies for sustainable management. This tool works beautifully for inquiry‑based learning, case studies, and assessment tasks. It also supports cross‑curricular links with Science (ecosystems, climate change) and Civics (community decision‑making). The visual nature of Timelapse makes it highly engaging and accessible for diverse learners.

Five practical tips, tricks and ideas for the classroom

• Compare two contrasting locations (e.g., Perth vs Darwin) to explore different patterns of growth
• Use the “share location” feature to create a curated list of sites for students
• Have students annotate screenshots to explain causes and impacts
• Use Timelapse as a hook for sustainability projects or persuasive writing
• Explore Australian case studies such as the Murray–Darling Basin or Great Barrier Reef coastlines
