Everybody Jump Now!
There are 7 billion people on Earth now; so many more than ever before. We are changing the face of the planet, but could we all get together to change the planet itself?
Could We Knock Earth Out of Orbit?
The size of the human population is having a large effect on Earth by changing habitats, altering climate, depleting resources and many other things. Since the human population is so massive we might wonder what we could do if we made a plan. Maybe we could change the length of the day or change the seasons. Maybe we could knock Earth entirely out of its orbit! At least we could start a big earthquake, couldn’t we?
With the link below, learn more about the effects humans can have on our massive Earth. Then answer the following questions.
- VSauce, What if Everyone Jumped at the Same Time (watch to 3:52 only): http://www.youtube.com/watch?v=jHbyQ_AQP8c&list=TLig3-2UOKkOk
- What would happen to the length of a day if everyone on Earth lay down at the same time? Why?
- What did the massive earthquake in Japan do to day length and why?
- If 7 billion people stood shoulder-to-shoulder in the same spot and then jumped, what would happen?
- How many people would need to jump at the same time to recreate the Japanese earthquake?
