My Youtube Videos

I have a collection of youtube videos that I filmed.
Most of the videos are for classroom demonstration but there are a few that are just for fun.
To see all my videos go here: http://www.youtube.com/user/mrsciguy

Pangaea An animated video showing the formation of the ancient supercontinent of Pangaea. The cut-outs come from our lab books.
Supercooled Water 2 A sequal to the popular "Supercooled Water". The original was so popular that it generated too many questions to answer so I made #2 (chuckle!) to provide enough details to supercool water yourself.
Supercooled Water The original video showing supercooled water freezing instantly.
The Doppler Effect A classroom demonstration showing the shifting pitch of a sound as the object making the sound moves relative to the observer.
The Big Bang A classroom demonstartion showing some of the observed effects caused by the Big Bang.
Levitating Worlds Ping pong balls floating on a cushion of air are used to show the movements of the Earth, Sun, and Moon during lunar phases and eclipses.
Making 3-Dimensional Projections Video showing how to make floating images used for astronomy with fairly common equipment.
Making a Tornado in the Class A demonstration showing the construction and use of a tornado box. The box creates a tornado that is over five feet tall!
Egg in a Bottle This classic demonstration shows the effects of air pressure changes when air's volume increases or decreases.
Clouds in a Bottle A simple demonstration that shows what conditions are necessary in order for clouds to form. A neat and clean demo with cheap equipment which allows each student to do their own cloud bottle if desired.
Seeing Infrared Light A simple demonstration that allows students to see a form of light that is normally invisible to most humans.
Boiling Water With Ice A demonstration that shows the lower boiling point of water when the air pressure is reduced (hence, special directions for cooking while in the mountains!) Watch till the end, this video has an interesting twist at the end!
Boiling Water With Ice 2 A sequal prompted by a critic who accused me of using some chemical other than water in "Boiling Water with Ice 1".
Crushing A Can With Air Pressure A popular demonstration that shows the effects of an imbalance of air pressure on objects surrounded by air.
Making a Topographic Profile This video guides students through the completion of a topographic profile starting with a scale model of a land feature and ending with a completed topo map and profile.
Formation of Hawaii This simple demonstration shows how a stationary mantle hot spot can produce a chain of volcanic islands on a moving crustal plate.
Mr. Medina's Evolution of Dance The ever popular performance at the annual Cabaret Night showing my version of the the original youtube hit.
