Black Holes

Have you ever wondered what happens to a star when it runs out of fuel or how something can pull in light itself? This worksheet helps you explore black holes, some of the most mysterious and powerful objects in the universe. You learn how they form, why their gravity is so strong, and what scientists do to study them. Each activity shares big ideas in a clear, kid-friendly way. As you learn, black holes become exciting instead of confusing.

You begin by discovering that black holes form when a massive star collapses under its own gravity. When the star’s core becomes too dense, its gravity becomes unstoppable, pulling everything inward. Activities help you picture this dramatic process and understand why only very large stars can create black holes. You begin to see how space can bend and stretch in extreme ways.

Next, you explore the event horizon, the invisible boundary around a black hole where nothing—not even light—can escape. You learn how getting closer to this boundary makes gravity stronger and time behave differently. These ideas help you see why black holes are both fascinating and challenging to study. Each activity encourages you to think about how the universe behaves under extreme forces.
