What if…?

It’s Science Day on Wednesday (yahoo!). To celebrate, have a think about this Scientific puzzle….

What do you think would happen if everyone on our planet (all 7 billion of us) jumped 30cm high in the air all at the same time? Would the Earth move? Would it cause an earthquake?

What do you think? Comment your ideas below and give reasons in your explanations. Don’t google the answer – just use your own ideas at this stage.

  1. I think if everybody was evenly spaced out somehow, nothing would happen – just a loud noise. However, if they were all packed together, one your ears would jump out the window, two there’d be a disturbance in the force……… Of gravity!
