I chose this video because it is a short, accurate, and rather 'dumbed down' version of what happens with tides. Because of the physical examples due to the soon, moon, earth, and ocean, it was easier to understand exactly what happens. I already had a rather good knowledge of tides but this video just made the knowledge set in stone. I also really liked how the person teaching was someone our age so she knew how to explain things in a way that other students who have also recently learned about tides could understand.
Enjoy!
