This is a recording of a recent live teleclass I did with thousands of kids from all over the world. I’ve included it here so you can participate and learn, too!


We’re ready to deal with the topic you’ve all been waiting for! Join me as we find out what happens to stars that wander too close, how black holes collide, how we can detect super-massive black holes in the centers of galaxies, and wrestle with question: what’s down there, inside a black hole?


Materials:


  • marble
  • metal ball (like a ball bearing) or a magnetic marble
  • strong magnet
  • small bouncy ball
  • tennis ball and/or basketball
  • two balloons
  • bowl
  • 10 pennies
  • saran wrap (or cup open a plastic shopping bag so it lays flat)
  • aluminum foil (you’ll need to wrap inflated balloons with the foil, so make sure you have plenty of foil)
  • scissors

  1. Aurora Lipper says:

    An object into a black hole may reach a speed that is equal to (or higher) than the speed required to escape. But, the object is being pulled toward the black hole. That means it is just going to plow into the black hole at a faster rate.

    Student question for you:

    Why is it that an object falling into a black hole doesn’t reach escape velocity during its decent if the gravity is so strong?

    I never knew about black holes. Thanks for showing me.

  4. We’re checking with the people who provided the video. Hopefully we can help you get it.

    I can’t get the exploring black holes pdf poster file. Can you help me?

  6. Sure! It is an Adobe Acrobat file. Feel free to download and print it!

  7. Can you print out the black hole map?

  8. After watching the class, which ways did you pick up on?
