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
Unfortunately, the poster is no longer available. However, I updated the link to the game.
The included links aren’t working.
“Download the Exploring Black Holes PDF poster file and also try playing the Black Hole Space Travel game…”

why do doctors use x rays if they are danger to our body
Has a human ever died by falling in a black hole
The answers are printed on the slides as we go through the presentation. The write-in answers are underlined on each slide.
Is there an answer key?
I do not see an answer key for this lesson. Am I missing something? Thank you!
