I came across a video via The Education Technology blog and want to share it with you below. It's an ad for National Geographic, for a series they're doing on global population. I think this would make a great video to share with kids when they are grappling with concepts like population, or even large numbers in maths. It makes a useful starter for a discussion about the environment, or any studies involving population growth. And I think it's an excellent example of an ad that grabs our interest and communicates its message clearly. I hope you have time to watch and discuss it with your (older) kids.
You can read more about it at the website, ask kids to think about how much space we would need to host a world party for 7 billion people in 2011, and play a biodiversity game too. Good luck with the game - I was so far out I am ashamed to confess it!
