NASA | Afterschool Universe: Stellar Fusion Demonstration
About | Information | History | Online | Facts | Discovery
Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe beyond the Solar System. This video shows a simple activity with clay that demonstrates the stages of fusion within the core of a star. Depending on its mass, a star can fuse and create many different elements before it finally runs out of fuel.

Everything is literally stardust.

Bs!!! A tennis ball is not neon!
-
"..and it's days are numbered [fullstop]" brief boom. lol

Helium has 2 protons, 2 neutrons. He + He = Beryllium isotope 4p, 4n but that is not stable because it is missing a neutron, Beryllium is 4p, 5n. He + He + He = Carbon 6p, 6n and is stable.

Very cool explained. Thanks!!
-
Nature abhors a naked singularity ;)
-
You need to get a better monitor cause I see the colors correctly here lol
-
Why do Helium atoms fuse to make Carbon, instead of Lithium, the element after Helium?
-
Afterschool. Bang Bang Bang <3
-
As an adult, I LOVE THIS.
-
is the sun really yellow?
-
Sooooo, are we gonna die?
-
good explication! :D
-
You're not wrong. It happens in so called r-processes - rapid, where you have neutron capture, and proton capture. And you have heavy elements forming and dissipating trough the galaxy :)
-
Excellent!!
-
Shes color blind... Lol the "pink" clay is actually red and the "blue" clay is actually green.
-
playdoh!! fun!
-
was waiting for the final boom!!!
-
Fe iron need energy to be in? Isnt it the same as other previous atoms that are lighter? I dont get this part. Someone explain to me.
-
If a star can make elements only up to Fe iron, where the rest of the heavier elements come from?!
