Model of a black hole science activity for kids: Many children may have heard of black holes and already have the understanding that they are “bottomless wells". If something falls into a black hole, it is impossible for it to escape — even light cannot escape and is swallowed. The lack of light is how black holes get their name. These objects are mysterious and interesting, but they are not easy to explain. This activity will allow children to visualize, and therefore help them decompose, the concepts of space-time and gravity, which are integral to understanding these appealing objects.
