The Vietnam War lasted for decades, with the North Vietnamese engaging South Vietnam, the United States and other allies in a protracted guerrilla war. The fighting raged across jungles, in the air, and even underground as both sides vied for supremacy.
During this drawn out conflict, some of those who fought there found themselves in situations that were more deadly, more terrifying, or just plain more unpleasant than soldiers that were fighting elsewhere.

This finance video tutorial provides a basic introduction into two liquidity ratios - the current ratio and the quick ratio also known as the acid test ratio. The current ratio is equal to the current assets divided by the current liabilities. A current ratio that is greater than 1 means that the current assets are greater in value than the current liabilities. The quick ratio is equal to a company's liquid assets divided by its current liabilities.

In addition, it has a few examples and practice problems on electric power, cost of electricity in Kwh and other stuff as well. It provides visual drawings, equations, and formulas as well as the units of common variables that you'll encounter when dealing with electricity. It discusses the difference between conventional current and electron flow. The unit of electric current is the ampere or amps for short. The unit for resistance is ohms and for voltage is volts. 1A is 1C/s or 1 coulomb per second. Electric current is the rate of electric charge flow. Charge represents the quantity of electrons in the case of metal conductors. The unit of power is the watt which is 1 Joule per second. Power is the rate at which energy is transferred. Equations used include V=IR, P=VI, and Q=It.

This physics video tutorial provides a basic introduction into torque which is also known as moment of force. Torque is the product of force and lever arm also known as moment arm. The lever arm is the perpendicular distance between the axis of rotation and the line of action of the force. Torque is the rotational equivalent of force. Positive torque values produce counterclockwise rotation and negative torques produce clockwise rotation. This video contains plenty of examples and practice problems of torques as it relates to doors, seesaws, and shovels. It discusses how to calculate the mechanical advantage of simple machines like seesaws and shovels.

The process of completing the square for a quadratic expression, equation, or function can seem confusing at first.

What do you do when a=1?

What do you when a is not 1?

Well, with the method discussed it doesn't matter what value of a you are working with.

Because young children have an interest about the world around them and want to know how things work, science is a subject that is captivating for young students in Preschool and Kindergarten. Here at Kid’s Academy, we explain the concepts of sound and light clearly and easily and students can’t help but want to learn more! In the videos, teacher Andrew and the fun cartoon character, Ball-y, explain these concepts with light and sound experiments for Kindergarten and 1st grade.

This series of videos teaches students what sound and light are as well how sound and light are made. In addition to teaching that sound and light are energy, there are experiments for kids that the videos demonstrate for the children to see and do on their own. Students may not understand how sound waves travel. The videos show sound wave experiments to explain this concept. Pluck a guitar string and see the vibrations, or watch how rice on a baking sheet vibrates when held over a speaker playing loud music. Other sound experiments for students include listening to sounds and trying to guess what makes the sound.

Students also learn how we use sound and light to communicate. When discussing light, students learn that traffic lights, lighthouses, and lights on radios, phones and appliances all tell us something. Sounds communicate to us too. Doorbells, sirens, school bells and whistles use sound to convey a message. Do sound experiments for kids and brainstorm other ways that light and sound communicate to us! Or, think of new ways that sound and light can be used.
Kid’s Academy includes a review video that teachers use to summarize the concepts in this lesson series. The review video defines light and sound again, shows how light and sound travel to our eyes and ears and then to our brain, and gives examples of light and sound.

When incorporating these science videos into your classroom, the concepts of sound and light are clearly explained. The videos show experiments for kids that encourage and engage students to learn and explore their world!

Explore input and output tables with this fun video! In this lesson, students watch a fun animation with Teacher Michael as he demonstrates finding a rule of a function with robots and machines. Students determine whether or not input and output tables follow a rule by watching Teacher Michael perform a task with the robot to determine the rule. Each robot has a rule on its body and a set of numbers displayed on two different input and output tables.

Teacher Michael explains that the rule works for only one of the tables and shows the viewer how to determine which table the rule demonstrates. The video includes humor when the robot seems to nearly overheat or explode when the numbers tested do not demonstrate the rule. Teacher Michael clearly defines input as what goes in and output as what comes out using the robots and the machines. He then instructs the students to study the inputs and outputs to figure out the rule. Teacher Michael defines the rule as the code or operation that determines the output. The result is a visual that students doing 1st grade math easily understand. The video demonstrates finding a rule of a function with two different rules: +2 and -4. Teacher Michael also emphasizes testing the rule with more than one input to ensure the rule works for that table.

Understanding input and output tables and finding the rule of a function teaches students math patterns. Students doing 1st grade math can look at inputs and outputs and see that if the output is larger than the input then the rule is an addition rule and if the output is smaller than the input then the rule is a subtraction rule.
Watch your student’s number sense and confidence in math grow with an understanding of inputs and outputs.

Hickory Dickory Dock song is a freshly modified video version of the traditional rhyme for kids aged 4 and under. It mimics the sounds of a grandfather's clock ticking and chiming on the wall.
Originally the words ‘hickory’, ‘dickory’ and ‘dock’ meant ‘eight’, ‘nine’ and ‘ten’ in the Celtic language. These days this is number one rhyme for introducing the basics for time telling. Kids listen, repeat and sing the rhyme to learn to tell the times. Below you can find lyrics to Hickory Dickory Dock song.

Lyrics:

Hickory dickory dock,
The mouse went up the clock.
The clock struck one,
The mouse went down,
Hickory dickory dock.
Hickory dickory dock,
The bear went up the clock.
The clock struck two,
The bear ran down,
Hickory dickory dock.
Hickory dickory dock,
The parrot went up the clock.
The clock struck three,
The parrot went down,
Hickory dickory dock.
Hickory dickory dock,
The monkey went up the clock.
The clock struck four,
The monkey went down,
Hickory dickory dock.
Hickory Dickory dock,
The pig went up the clock.
The clock struck five,
The pig went down,
Hickory dickory dock.
Hickory Dickory dock,
The elephant went up the clock.
The clock struck six,
The elephant went down,
Hickory Dickory dock.

The video is an ideal resource to introduce and learn the names of animals for toddlers. They will learn animals in no time! Not only the rhyming song is a hundred percent fun and crowd-pleaser, but also a perfect time saver.
