Calculus Limits: A Numerical Approach
In Calculus, the term limit is used to describe the value that a function approaches as the input of that function approaches a certain value. This video explains the two ways to demonstrate Calculus limits: a numerical approach or a graphical approach. In the numerical approach, we determine the point where the function is undefined and create a table of values to determine the value of the variable as it approaches that point. (1:45)
One-Sided Limits
This video explains one-sided limits. A limit is the value that a function approaches as the input of that function approaches a certain value. In Calculus, sometimes functions behave differently depending on what side of the function that they are on. By definition, a one-sided limit is the behavior on only one side of the value where the function is undefined. (3:02)
Calculus Limits: A Graphical Approach
This video explains the graphical approach to determine a limit. There are two ways to determine a limit: a numerical approach or a graphical approach. In the graphical approach, we analyze the graph of the function to determine the points that each of the one-sided limits approach. (3:02)
Infinite Limits: Vertical Asymptotes
This video explains when a limit decreases or increases without bound near certain values for the independent variables, they are called infinite limits. In general, a fractional function will have an infinite limit if the limit of the denominator is zero and the limit of the numerator is not zero. The infinite limit can be either positive or negative and is determined by the sign of the quotient of the numerator and the denominator. (3:23)
Continuity of a Function
This video explains the three conditions that must be met in order for a function to be continuous at a certain point. The continuity of a function only exists if these three conditions are met. (0:55)
Averages (in Algebra)
Introduction to averages and algebra problems involving averages. This video starts off with a black screen because the narrator uses it as a 'chalkboard'. This video is appropriate for older mddle and high school students.

Land Of The Tiger - Monsoon Forests, Part 2
This documentary, which is suitable for older elementary, middle school, and high school students, explores the wildlife of the Indian subcontinent living in the rainforest. 9:50
Molecules in Liquid
As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.Â
Learn about Fuel Cell Technology
Many researches have been working on renewable, clean energy sources. This particular study shows how hydrogen may some day replace gasoline to fuel our vehicles with zero emission of fuel cells. Learn about real world testing of this fuel cell technology. Run time 01:50.
A Night in the Coral Reef
This video segment, adapted from NOVA, explores how a coral reef ecosystem changes over the course of a day. When the sun is up, colorful fish and other plant-eating animals are active and dominate the reef. At night, the plant-eaters take shelter and are replaced by nocturnal carnivores, some of which exhibit special adaptations that enable them to successfully hunt in complete darkness. Closed captioning included. Run time 02:49.
