What it is

  • In this resource from Population Education, students will analyze an interactive map and timeline, showing how the global population has grown over time.
  • The timeline also shows key events that happened over time in the areas of food and agriculture, health, science and technology, people and society, and the environment.
  • Students can also toggle overlays to explore emissions, land use, fertility rates, urbanization, and life expectancy.

Teaching tips

Positives
  • This map has many overlays and features to explore a variety of topics.
  • The resource includes a helpful page on how to use and navigate the map and timeline. Teachers can find this by clicking the menu.
Prerequisites
  • Teachers should go over how to use the interactive with students, making sure to point out key features and tools that will be the most useful for their purposes.
  • Many of the overlays only have data for a certain period of time within the timeline. When users select these overlays, the timeline will only play for that data range.
  • To restart the timeline, users need to pull back the playhead to the beginning.
Differentiation & Implementation
  • Teachers can use this map to explore major events and demographics that can be connected to the Sustainable Development Goals. This resource connects especially well to SDG 2, Zero Hunger, SDG 3, Good Health and Well-Being, SDG 14, Life Below Water, and SDG 15, Life on Land.
  • To demonstrate the Industrial Revolution impacted CO2 and fossil fuel emissions, teachers can select this overlay, drag the timeline bar to a few decades before the Industrial Revolution, and press play.
  • For a student-guided exploration of this resource, teachers can play the standard timeline and map animation for students, having them write down what they notice and wonder about population growth and its impacts. Teachers can use these wonderings to guide instruction.

From the scientist review

This video discusses how an increasing population puts strain on the Earth's resources, and depicts how the Earth's population has changed and is expected to change over time. The resource does not discuss how the population of some areas is decreasing, but focuses on Earth's population as a whole. The video includes a thorough explanation of what the map shows, and is a great example of how to explain visuals. The information presented is accurate, and this resource is recommended for teaching.
