We would like to share this brilliant online resource, the World Population History website. It shows a timeline of the population growth on Earth from AD 1 to current times, with corresponding societal, environmental and technological events and advances. This can be a brilliant resource when teaching civilisations, historical events and much more.
If you head to the Teachers' Resources section, you can find ready-made lesson ideas and resources to help you use this tool in your lessons. It could be particularly useful for secondary schools in building a stronger contextual understanding between and across different subjects.
