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.
High Current Electrical Discharges
Lightening is a high current electrical discharge in the atmosphere. Learn more about how these electrical discharges occur in this educational video from dizzo95. Run time 01:04.
Basics of Geography: Climate
Discusses what makes up geography; land, water, people and their lives and how land and water affect them. Geography also includes climate. Climate is the weather pattern in a region of the world over a long period of time. One of the major factors affecting our climate is the Sun. The way the Earth moves around the Sun affects the climate. This video discusses rotation, revolution, year, axis, hemisphere, latitude, lines of latitude, and equator. This video discusses what causes the different c

DNA Replication and Protein Synthesis - Rap
Fun music video that explains the processes of DNA replication and protein synthesis. This would make a good review for students. Color video and animation, with music, narration, and subtitles. (03:30)
Evolution vs. Intelligent Design
Explains the difference between the theory of evolution and intelligent design. Discusses the reason intelligent design cannot be tested using the process of science. Explains the difference between falsifiable hypothesis and irreducible complexity. Uses images with narration and subtitles. 6:59 min.
Time, Stonehenge and Sundials
A short video moving through the history of human attempts to measure and record time. Daniel Boorstin, author of "The Discoverers" commented that "The first grand discovery was time, the landscape of experience." This video is intended as an introduction to the three accompanying videos on designing and constructing sundials: The four videos in this series are "Time - 1", "Our Planet is a Clock - 2", "Sundials and Latitude - 3" and "Create a Sundial - 4"

Inner Rocky Planets - Part 2
This video focuses on the little jagged worlds (or Inner Rocky Planets) from their birth to this day, and their compositions, structures, and their differences. (05:18)
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
