We have an entire collection of student made videos, that give a short explanation of entropy and the second law.
Additionally, Khan Academy has a great selection of videos on both chemistry thermodynamics and physics thermodynamics.
This video explains the concept of entropy using the example of a Glade plug-in. It also helps visualize entropy by using food coloring in water to show how molecules tend to move from a state of higher organization to a state of lower organization.
In this video, students explain the concept of entropy through a variety of examples, including cards, puzzle, pieces, and a broken flower pot. Because of it's many examples, it is a good video to watch if you are still confused about what entropy is and how it works.
This video provides an overview of the second law of thermodynamics. It touches on a number of examples of how molecule move or behave because of this law and it also touches on how you can reverse, or go against the second law.
In this video, entropy is explained through the example of a desk that keeps getting messier, even after being cleaned.

Here is a Khan Academy video explaining the mathematical definition of entropy and how it is related to the second law of thermodynamics.
