Hands-on activity:
In-person: Magnetic slime
Online: Stretch slime
Glue(1 cup)
Contact solution(1 tablespoon)
Baking soda(1 teaspoon)
lotion(as much as you want)
Mix everything together
Hold the slime in your hand stretch it
Now imagine that the slime is your body being pulled towards a black hole, it will slowly stretch your body.
Facts:
Black holes slow down time. Imagine that you are traveling through space, once you reach the event horizon, due to the gravitational pull from the black hole you are moving at such high speeds which causes it to slow down time. Think about the twin experiments. One twin would go to space, turn around, and come back while the other would stay on Earth. The twin that went into space would look quite a bit younger than the one who stayed on Earth because they were moving at such high speeds.
Black holes will slowly stretch your body. Imagine a bunch of stretchy cheese and you’re trying to pull that apart, that’s what it would be like if you tried going into a black hole, your bones would break, your muscles would stretch out so far they would completely break and pop, you wouldn’t live after entering the black hole. The worst part about this is that black holes slow down time so while everything is breaking it’s happening slowly. This is because your feet are closer to the center of the Earth and are more strongly attracted than your head. Under extreme gravity (near a black hole) the difference in attraction would start to work against you.
Stars that die can turn into Stellar black holes. Imagine that you are blowing up a balloon. The balloon gets bigger and bigger as you fill it with air and soon it will get so overwhelmed with oxygen that it will pop. This is essentially what is happening to the stars when they turn into black holes. When pressure from the nuclear reactions collapses, gravity overwhelms and slumps the stars’ core. The rest of the star’s layers are thrown into space, this is also called supernova. After the star’s core collapses, a spot that is overcome by density and without volume - a black hole.
Three categories of black holes. Most people would think that there’s only one type of black hole, but the truth is they have three categories: stellar, primordial, supermassive The most common type is stellar, a stellar black hole is created when a star's gravitational force collapses. They can also be up to 20 times bigger than the sun. The smallest black holes are called Primordial black holes. They can range anywhere from the size of an atom to the mass of a mountain. The biggest black holes are called Supermassive black holes. They are more than 1 million times larger than the sun.
