I came across this powerful video that explains global development is in a visual and easy-to-understand way. I use it with my 9th grade students in Big History when we explore the Gapminder Dollar Street website, but it is applicable to other courses on the OER platform. The website it comes from offers rich information and compelling statitscs, and it pairs especially well with discussions around the UN's 17 Sustainable Development Goals. Highly recommend checking it out!
