Total time for both videos = 6:30 minutes
Substances are made of just one kind of particle so they CANNOT be physically separated into different components.
Mixtures are made of MORE than one kind of particle so they CAN be physically separated into their components. The first video below has a simple example of separating a mixtures using the different properties of the two components that were mixed together.
The second video describes the formal lab techniques that are used to separate the types of mixtures you would work with during a chemistry experiment.
