Gauss Jordan Elimination & Reduced Row Echelon Form
Gauss Jordan Elimination & Reduced Row Echelon Form Teacherflix 6 Views • 2 years ago

This precalculus video tutorial provides a basic introduction into the gauss jordan elimination which is a process used to solve a system of linear equations by converting the system into an augmented matrix and using elementary row operations to convert the 3x3 matrix into its reduced row echelon form. You can easily determine the answers once you convert it to that form.

Resistors In Series and Parallel Circuits - Keeping It Simple!
Resistors In Series and Parallel Circuits - Keeping It Simple! Teacherflix 13 Views • 2 years ago

This physics video tutorial explains how to solve series and parallel circuits. It explains how to calculate the current in amps through each resistor and the voltage in volts across each resistor with three resistors in series and parallel combination using a few simple formulas including ohm's law. Parallel resistors form a current division circuit and series resistors form a voltage division circuit. This video also explains how to calculate the electric power delivered by the battery in watts and the power absorbed by the resistors.

WWI Tanks: A7V Tank
WWI Tanks: A7V Tank Teacherflix 8 Views • 2 years ago

Germany was unusually slow to realise and develop a tank, considering that in 1916, the British and the French had introduced tanks on the battlefield.

When the British used their new tanks at the battle of Flers-Courcelette, in September 1916, the Germans shocked, finally realised that they needed to design their own tank...

-----
Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to know why the stars, shine!

In summer, I love to watch the stars shine bright. They make me think and look back on many things…

Stars shine because they are gigantic burning hot gas spheres that release heat and light. They are so bright because there are atomic reactions inside them, that convert hydrogen into helium. Their temperature can reach 10.000 degrees centigrade. According to the colours they give off, astronomers know if they are hotter or cooler.
Our sun is a medium sized yellow star. Stars smaller than the sun are reddish and larger ones are blue.

Stars live for thousands of millions of years, but they always end up becoming extinguished.

When we look into the sky at night we can see hundreds and hundreds of stars. Some of them, either because they are very big or because they are closer to Earth, are very visible. Others, which are smaller or further away are tiny points that can hardly be seen.

At a glance from Earth, we can see about 2000 stars, but really, there are thousands and thousands of stars in the universe, but nobody knows exactly how many there are.

In the past, stars were very important for sailor’s orientation. Because of the Polar Star, the Ursa Major or Venus, sailors knew what directions to take and got to their destinations safe and sound. To see the stars better, they used devices such as the telescope.

The telescope is a gadget that works with light and is used to watch far away objects a lot clearer than by glance.
But… who was the inventor of the telescope?
The truth is we don’t know with certainty, but it was Galileo in 1609 who, using an invention by a Dutch man called Lippershey (Lipershy), built the first telescope that was used to look at the stars and because world famous.

Well, now we know why stars shine and the instrument so we can look at them. The truth is I love stars. What about you?

Martin Luther King Jr | A documentary about the monumental impact of MLK Teacherflix 8 Views • 2 years ago

Martin Luther King Jr for Kids is a short documentary and overview about the great civil rights leader. Together we will learn about the monumental impact he had and still has throughout the world.

MLK – They are three letters representing the Civil Rights movement in America during the 1950s and 1960s. Of course, the letters belong to the name- Martin Luther King Jr. Nearly everyone has heard of this Civil Rights leader, but many people do not know the journey of his life.

They see him as the person honored on the 3rd Monday in January
each year, giving a day off from school or work. However, there is much more to be known about this great leader, including his early life, education, religious background, civil rights activities, and much more.

»»-------------¤-------------««»»-------------¤-------------««

Q. Does Numberock drive real results in the classroom?
A. I knew I found the secret sauce when not only were my students retaining the concepts longer, they were singing the songs outside of the classroom during recess and at home with their parents during dinnertime. The songs were so catchy, my students couldn't get the math songs out of their head!

During testing, I often found my students humming the melodies in order to jostle their memory of a rule or problem solving process. As we've all experienced, there is something about the power of music that allows us to retain information easier and for longer periods of time. Without getting into the finer details of multi-sensory learning and how it often helps the students who most need the help, the power of a catchy song is hard to deny.

Newly Available for Website Subscribers:
1. Number Notes | Highly-visual math worksheets that integrate drawing and creative processes that make problem-solving and note-taking way more fun.

Research has shown that resources like these worksheets help students to integrate their artistic side with the mathematical side of their brain and as a result aides with long-term memory retention.

Our own research has shown us that teachers who try these activities love them! It seems to be a natural extension beyond song and video and into additional visual learning tools that when used in concert with our videos, cater to the many different types of learners that in your classroom - especially those non-mathy types.
