Basic Math: Lesson 6 - Video Clip #9 - Arithmetic of Fractions: Addition
Concepts covered: Addition of Improper and Proper Fractions and also Mixed Numbers.
Adding Integers with a Number Line
Instructor uses an interactive white board to show to use a number line to aid in the addition of integers. This video does add with negative numbers. Clear lecture and good examples. (6:29)
How to Use the Quadratic Formula to Solve Algebraic Equations
Using the quadratic formula to solve equations may bring one, two, or no algebraic solutions. The quadratic formula is special to quadratic equations. Run time 03:24.
Ways to Determine a Prime Number
A prime number is a positive whole number with exactly two
factors, which are one and itself. A math teacher shows how to use multiplication tables and factor trees to help determine if a number is a prime number.
Applications of Linear Equations
This video clip describes how math is applied to the real world situations through word problems. The applications of linear equations are seen throughout all our math courses after Algebra. To understand applications of linear equations we need to have an understanding of slope, how to interpret a graph, and how to write an equation. In upper-level Algebra, we apply systems of linear equations to these problems as well. (1:45)
The Largest Flower in the World; Titan Arum
In this video, suitable for all grades, David Attenborough looks at one of the largest flowering plant in the world, if not THE largest flowering plant. Wouldn't you think a plant this large would emit a wonderful fragrance? It is sometimes called a Corpse Flower because the smell is that of a rotting corpse.
The desert biome is characterized by low precipitation, a high rate of evaporation (seven to fifty times as much as precipitation), and a wide daily range in temperature. The dramatic temperature fluctuations are the result of low humidity, which allows up to 90 percent of solar radiation to penetrate the atmosphere and heat the ground during the day, then for this accumulated heat to be released back into the atmosphere at night. Precipitation in deserts, unlike other biomes, is highly irregula
SAT Prep: Test 5, Section 7, Part 1
Students, improve your math SAT score! The instructor uses an electronic chalkboard to model problems. This video is appropriate for high school students. Uses a textbook (the official SAT study guide) commonly found in bookstores, but it is not absolutely necessary as the narrator does all work on the screen. Problems 1-5 starting on page 669.
From Seed to Flower
The growth and development of a plant is one of the most spectacular events in nature. Yet, because it happens so slowly, over the course of days or weeks, it is difficult to observe in real time. This video segment depicts plant growth in time-lapse format, allowing the viewer to observe in just a few seconds some of the most important life stages of a plant, from germination to the formation of a flower, and several phases in between. Footage from NOVA: "The Shape of Things." Set to music. N

Pop Quiz: Parent Involvement
How well are you doing at being involved in your child's education?
This video gives a brief description of a Stem-and-leaf plot, how to make them and use them to find the median and range.
Relative Frequency Histogram
In this video, an unfinished histogram is pictured. The instructor explains how to complete the histogram and does each step necessary to do so.
Drawing a Histogram
This lesson takes provided data about mass to create a histogram about the data. While the lesson relates to a previous experiment, it still provides good step by step instruction on how to draw a histogram. Graph paper will be needed to follow along and complete the lesson along with the instructor. It is hard at times to see what the instructor is writing because the writing is very small.
In this video (06:08), Mr. Khan explains how to visualize data using a histogram. Mr. Khan uses the computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
How Music Works 2 - Rhythm - Part 1
