In this lesson, the lesson explains what polynomial functions are and provides examples. Then, he explains some relevant terminology such as "leading coefficient" and "constant term". The instructor shows and explains a chart with the standard form for five different types of polynomials (constant, linear, quadratic, cubic, and quartic). The lesson finishes with a variety of examples.
Introduction to Angles and Angle Types
In this video a math instructor introduces angles that are used a lot in math. He explains what angles are, how they are created, and the main types of angles we used in math.
Solving Systems of Equations by Substitution
This lesson is for ntermediate Algebra Level. In the lesson, Professor Burger shows how to solve systems of equations using a technique known as substitution. In this approach, students solve one equation for one of the variables (eg y) and then plug the value (what y is equal to) into into the other equation (anywhere a y appears). This substitution will allow you to solve for x and then in turn solve for y. Professor Burger walks the viewer through several different types of
Simile, Metaphor, and Personification
The instructor uses a whiteboard and clip-art cut-outs to demonstate three types of figurative language. This video is suitable for third-grade students and older. (Note: The instructor dellberately has the first few seconds blurred.)
What is Psychology Part 2 of 2
In this video, the professor discusses how to become a psychologist in one of the varying types. It also shows the four major goals of psychologists. The video is changing texts with narration. Run time 09:03.
Why do leaves change color in the fall? As autumn approaches, the countryside puts on a spactacular show. This short, computer animated video covers the following key concepts: autumn leaves and their colors, factors that affect leaf color, chlorophyll, carotenoids, anthocyanins, chlorophyll production and decline, tree types and their varying colors, leaves falling, and leaf decay. The video ends with a 10 question, fill in the blank quiz.
Telling Time to the Hour With the CooCoo Bird This live action movie and cartoon characters help children learn to tell time. First children are asked why it is important to tell time; know what time to wake up, know when to get the bus, when to play, when to take a nap, and many more reasons. Then video goes into the different types of clocks. (5:42)

How Is Nuclear Energy Harmful?
Nuclear energy can be harmful when radioactivity is absorbed by
cells of the body. Discover how radioactivity can damage bone marrow and red blood cells with information from a science teacher in this video.
Weather : What Causes Wind-Driven Currents?
Wind-driven currents are caused by the return of large circulation cells, of which there are three between the equator and the poles. Find out how circulation cells also move heat over the planet with help from the chair of a department of environmental studies in this video (02:29) on wind-driven currents.

Bio: Dr. Jack Hall is the department chair in the department of environmental studies at the University of North Carolina at Wilmington.
Video shows how warm fronts are shown on weather maps and what warm fronts are. The video also includes the cloud types that are seen before a warm front occurs, the temperature changes, the wind changes, and the air pressure changes. Video gives all basic information needed to understand warm fronts. Video is of good quality and appropriate for elementary age students, especially for students who are studying weather in science.
Living Band-Aid Beats Like a Heart
Video shows current research in heart tissue structure and repair. Jordan Lancaster and Steven Goldman, researchers from the Southern Arizona Veterans Administration and the University of Arizona, put rat heart cells on a piece of synthetic mesh and within a few days, it started beating. The hope is that down the road the patch of cells could be used to treat damaged hearts.
This video is accompanied by text. "In the late eighteenth century, primitive methods of travel were still in use in America. Waterborne travel was uncertain and often dangerous, covered-wagon and stagecoach travel over rutted trails was uncomfortable, and all types of travel were very slow. Americans were aware that a transportation network would increase land values, stimulate domestic and foreign trade, and strengthen the American economy.
In 1794, a private company completed the Phila
Transformations - Translations and Reflections
This lesson focuses on explaining two types of geometric transformations: translations and reflections. The instructor uses a virtual white board to give examples and chances to select the correct answers.
Tessellation Slideshow of Students Projects
A musical slide show of 7th grade students tessellation projects. There is a definition at the beginning of the video of tessellation and where you can find tessellation. The video then shows how the students took a square and moved it into action using three types of tesselations-translation, rotation, and reflection.
Introduction to Scatter Plots
Brief description about scatter plots and lines of best fit. Various types of scatter plots are briefly described. The video goes over how to analyze data or recognize patters using examples. Some multiple choice problems are presented with answers given.
Learn a Trick to Making Box and Whisker Plots in Excel
See how to create a Box Plot or Box & Whisker Statistics chart
using a Stacked Bar Chart and a Open-High-Low-Close Stock Chart. The video show how to use the QUARTILE function and how to link Chart Labels to cells. The demonstration is done using the software program and the data sometimes is a little difficult on the screen.
Crohns Disease Module 6: Nutrition
Questions addressed in this module include: How important is diet? How can we optimize nutritional intake? Are there foods we should avoid? What types of nutrient supplements should we discuss implementing into our diet?
Solving Rational Equations
In this video, the instructor goes through two examples of solving rational equations. He works through the problems step by step and writes out each step as he explains it. The instruction is quite clear and thorough, making this good practice for these types of equations.
Malaria in sub-Saharan Africa
This video segment adapted from Rx for Survival examines malaria in sub-Saharan Africa, a disease that kills more than one million children there each year. It explains how a deadly parasite, a member of the genus Plasmodium, enters the bloodstream via a mosquito bite and how it multiplies once inside host red blood cells. The video reveals that drug counterfeiting has increased malaria's death toll, and that newer drugs, while more effective than older ones, are too expensive for most Africans
