Space and Time
Carve out some time to learn about space-time. Young scientists use a remote learning resource to read up on the relationship between space and time. They consider the idea of relativity, see how objects with a large mass can bend space...

Model of a Black Hole
Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.
