A rich-media collection of educational videos from the Ohio Public Television Stations that explores Language Arts, Social Studies, Science and Technology, Math, and Careers.
This video from WOUB Athens, presented as a parody of a popular TV network reality show, will help high school students review and prepare for the Ohio Graduation Test in Mathematics.
To show simple physical change, a banana is frozen in liquid nitrogen and used to hammer a nail into a piece of wood.
This demonstration shows chemical change with hydrogen peroxide decomposing into water and oxygen.
This demonstration provides an answer to the question, “What is the path producing the shortest possible time for an object to descend from a given point to another point, under constant gravity with no friction?”
In this demonstration of chemical change, the presenter blows breath into a methylene blue solution releasing carbon dioxide which acidifies the water and changes it from a bright blue color to green.
In this demonstration, stored energy in plants is made visible by shining a black light on the chlorophyll that has been extracted from chopped spinach.
This demonstration shows the effects of temperature on air and water inside a container. As the water inside a 1/8-inch cast iron container freezes, it expands causing the container to break.
This video from WOSU Public Media defines wetlands; describes their different varieties; and demonstrates why we should care about them.
This video shows how wetlands cleanse the ecosystem in ways similar to how kidneys cleanse the human body.
This video shows a sample of the large varieties of plants, animals, birds and fish that abound in wetlands and looks at the processes that sustain them.
This demonstration traces the transfer of thermal energy by conduction with the use of a space shuttle tile.
