Ocean Currents
We hear about strange things from distant places that get washed up on our shores all the time. But how did they get there? Learn more about ocean currents in this educational video from dizzo95. Run time 01:20.
What Causes Waves?
The major cause of waves, specifically ocean waves, is wind,
although waves can also be created by tides and earthquakes. Learn
how waves are simply the result of winds passing over water.

Lightning 101 Video
Learn about the forces that cause lightning. It is generally thought that lightening often occurs within the downdrafts and updrafts of thunderstorms.  Lighter particals moving towards the top of the cloud become positively charged while heavier particles heading towards the bottom become negatively charged.  When positive and negative charges grow large enough, lightening is released.   Run time 02:38.
Lightning
Learn about lightning, how it forms, and how to stay safe in this brief, computer-animated video. The following concepts will be briefly covered: the water cycle, evaporation and cloud formation, water condensation and rain, opposite charges attract, lightning formation, and lightning safety. The video ends with a 10-question, fill-in-the-blank quiz.

Learn to Speak French : Numbers 21 to 100
Suitable for all beginning French-language learners.
Catching Solar Waves
Kelvin-Helmholtz instabilities occur when two fluids of different densities or different speeds flow by each other. In the case of ocean waves, that's the dense water and the lighter air. As they flow past each other, slight ripples can be quickly amplified into the giant waves loved by surfers. In the case of the solar atmosphere, which is made of a very hot and electrically charged gas called plasma, the two flows come from an expanse of plasma erupting off the sun's surface as it passes by pl
