Scientific Method: Controlled Experiments
During an experiment, variables represent conditions that can be changed throughout the experiment. Scientists must be careful to test one variable at a time. The control is the standard for comparrison in an experiement. Run time 02:00.
ACT Math Content Review Part II
Instructor uses a power point presentation/ electronic chalkboard and focuses on Elementary Algebra in this ACT Math Review by brightstorm.com. This video is very clear and great quality.
The Golden Door - Immigration Documentary Part 2 Video is hosted by a group of students. Video discusses the 1882 Emigrant Act and 1917 revision of the act. The 1882 Emigrant Act charged fifty cents for each immigrant. This money was to be used for the care of the immigrant. In 1907 the law was revised, $4.00 was charged on any immigrant for the first time. The increase in immigration changed education in America. Immigrants nee

Heart Disease - Illumistream Health
Professional video explains what heart disease is and how the heart works. There are multiple conditions that affect how our heart works. The heart is a pump that pumps blood in and out of the heart. A doctor explains what is happening using animations and pictures. Atherosclerosis, angina, and aneurisms are discussed. 2:56 min.
Lecture lesson on subordinate clauses, also known as dependent clauses. This lesson shows that they function as if they were nouns, adverbs, or adjectives. Teacher on the clip shows examples of subordinate clauses on a whiteboard.
Solids, liquids, and gases are the substance of every substance in the physical world. With the quest for low temperatures came the discovery that, under the right conditions of temperature and pressure, all elements can exist in each of the basic states of matter.
Anatomy of a Kidney
There is a very brief video with still images of the kidney. This is a quote from the video:
"This cross section of a kidney, almost three times life-size, shows its blood supply and one of the filter tubules, a nephron, highly magnified. The nephron is a highly specialized coiled tubule measuring up to one inch in length. There are more than one million nephrons in each kidney. They function as the kidney's filter units. The kidneys filter unwanted materials from the blood and regulate th
The Function of the Liver
Did you know that the liver is the largest organ in the human body? Learn more in this computer-animated video (04:02) that describes where the liver is in the body and its function. This video has English captions at the bottom of the screen. This may be good for big classrooms where sound may not travel well.
Note: There is a little static as the narrator appears to be too close to the microphone while speaking. Also, in the summary the word 'learned' is spelled incorrec
How The Eye Functions: Part I -
Video which identifies the main structures of the eye and how they function. Although this is an old video in black and white, the information in good. Grades 7-12. 4:55 min.
How to Solve Direct Proportions
This video is geared for eighth-grade Algebra students. This video illustrates how to solve direct proportions. Examples and rules are presented on a white board. For additional exercises and worksheets follow the link provided at the end of the video.
Parallelogram and Trapezoid Comparison
This video makes comparisons of the characteristics of trapezoids and parallelograms. Addressing the question as to whether a parallelogram is also a trapezoid. The answer will depend on your definition of trapezoid. If a trapezoid has exactly one pair of parallel lines, then parallelogram doesn't fit within those conditions or parameters. If your definition of trapezoid states that is has at least one pair of parallel sides, then all parallelograms could be considered trapezoids. Your answer th
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing or learning place value. This video has humor, which helps make the lesson fun. Video shows how to use the number line, shows how to use the number line where the problem has more than two addends. Then they show how to add in different order by grouping numbers, knowing which numbers add up to 10 to make it easier. This video gives many examples to reinforce the lesson taught. Video is good qualit
Addition on a Number Line
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing or learning addition on a number line. This video shows how to add numbers using a number line, some of the numbers they use start with a negative, then they add a positive number. They show many different examples. They also use the number line to show how to find a missing addend, -10 + x = 2. Video is good quality and good for all students as review or initial learning of the concept.
Subtraction on a Number Line
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing subtraction. In this video they show how to subtract using the number line, this includes negative numbers. They do this using many different examples. Then they do a word problem using the number line and then equation form. Once again they do a few examples. Video is good quality and good for all students as review or initial learning of the concept.
Graphing Quadratic Functions
Instructor uses a white board to demonstrate graphing quadratic functions. Example models taking a quadratic function in standard form, determining if the function opens up or down, finding the axis of symmetry and vertex. The instructor then creates an x/y table and uses those points to complete the graph.
Step-By-Step Solutions for Algebra
Excellent video from Jimmy Chang, who has a master's degree in math and has been a math teacher at St. Pete College for more than eight years. Mr. Chang explains step by step how to solve problems in Algebra explaining the importance of showing all steps involved.
Beginning Algebra: Factoring Trinomials
Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Beginning Algebra.
In this lesson, you will learn how to factor trinomials using a reverse-FOIL trial-and-error method. You will start by simplifying the trinomial as much as possible, by removing any common factors or grouping any possible combinations. Then, try the reverse-FOIL by first breaking up the squared term. He also gives you a hint that when the last factor of the
Multiplying Binomials Using the FOIL Method
We could all wish that we had an educator like this when we studied Algebra. The instructor, Ed Burger, uses humor to explain the FOIL method. This video is a preview from Thinkwell's Intermediate Algebra course.
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
Basic Algebra : How to Write an Algebraic Expression
