Educational video for children in which they will learn the /s/ sound in English through a fun song and numerous examples alongside our favorite seal, Feli. Little ones will discover how to pronounce the sound of the letter s. Phonics is a very successful method used to teach reading through letter sounds. In this simple video for children who are beginning to read, we work on phonemic awareness and phonological awareness, two important skills for early readers and young children who are developing reading skills. It is an interactive video that asks viewers to participate by singing and repeating the sounds along with Feli.

This video is a very useful and interesting resource for children to learn the sounds of the Englishlanguage. It is an excellent video for infant, primary and bilingual education.

This electronics video tutorial provides a basic introduction into NPN and PNP transistors which are known as BJTs or Bipolar Junction Transistors. This video discusses the 3 operating regions of a transistor - the cutoff, active, and saturation region. It also explains how the transistors act as switches and how to determine the current and voltages in a transistor base bias circuit.

This video shows you how to subtract fractions when they have the same denominator. Subtracting fractions with like denominators is easy. All you do is subtract the numerators, keep the denominators the same, and simplify if you can.

Here is the video on how to simplify fractions: https://youtu.be/E_81dn_OYOA

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.

The library of math tutorials that I create can also be used as supplemental instructional material for homeschooled math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.

I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.

Improved math is creating more videos every day to cover topics from 4th-grade, 5th-grade, 6th-grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!

Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.

Everyone is talking about the black hole image, which is amazing! But I've been wondering where actually is the black hole? So here it is. It is inbetween the virgo and leo constellations. Although you can't see it (unless you have a planet sized radio telescope array), it is still nice to know where it is.

In which John Green teaches you about the United States Constitution. During and after the American Revolutionary War, the government of the new country operated under the Articles of Confederation. While these Articles got the young nation through its war with England, they weren't of much use when it came to running a country. So, the founding fathers decided to try their hand at nation-building, and they created the Constitution of the United States, which you may remember as the one that says We The People at the top. John will tell you how the convention came together, some of the compromises that had to be made to pass this thing, and why it's very lucky that the framers installed a somewhat reasonable process for making changes to the thing. You'll learn about Shays' Rebellion, the Federalist Papers, the elite vs rabble dynamic of the houses of congress, and start to find out just what an anti-federalist is.
