I’ve explained a lot of weird bodily functions on this show but there’s one that we haven’t covered that’s always confused me: Tickling. What are you for, tickling? What’s the point of you? Why do you exist? Why do you make us laugh even though we hate you? Let’s dig into our evolutionary past to try and find an answer.

Educational video for children that talks about some well-known genres of music. Each musical genre is different: there are differences in how they sound, how they are played, what instruments are used and even their origin. The first of today's music genres is reggae. Reggae is a style of music that emerged in Jamaica in the 1960s but became popular in the 1970s. Reggae bands usually use bass guitars, guitars, pianos, organs, trumpets and percussion instruments such as congas or drums. The second genre is salsa. Some say that salsa-like rhythms were heard as early as the 1930s, but it was not until the late 1960s that this musical genre became popular. The third genre is flamenco. Flamenco is a musical genre that originated in Andalusia, in southern Spain. It is not clear exactly when flamenco began. Although the word ""flamenco"" first appeared in the 18th century, it is believed that this musical genre is much older. The fourth genre is the mariachi. Mariachi music began in the 18th century in Mexico and has since become a very popular musical genre all over the world. Finally, there is tango. Tango originated among the European and African immigrant populations in Argentina and Uruguay in the 19th century.

This video is very useful and interesting for kids. It’s perfect for teaching about different musical genres. It’s an excellent video for elementary or primary education.

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 homeschool 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.



Thanks for watching my channel.

You may think you know all about hypnosis from the movies. Zoolander, The Manchurian Candidate, etc... but there's a whole lot more going on. In this episode of Crash Course Psychology, Hank tells us about some of the many altered states of consciousness, including hypnosis.

In which John Green examines the French Revolution, and gets into how and why it differed from the American Revolution. Was it the serial authoritarian regimes? The guillotine? The Reign of Terror? All of this and more contributed to the French Revolution not being quite as revolutionary as it could have been. France endured multiple constitutions, the heads of heads of state literally rolled, and then they ended up with a megalomaniacal little emperor by the name of Napoleon. But how did all of this change the world, and how did it lead to other, more successful revolutions around the world? Watch this video and find out. Spoiler alert: Marie Antoinette never said, "Let them eat cake." Sorry.

Kære venner
Hent spillepladerne gratis her: https://anettekmatematik.com/monster/

Monster er et sjovt spil der både kan bruges som break i undervisningen og som samtidig træner en masse gode ting hos eleverne.
De øver sig i talforståelse og i at holde styr på enere og tiere, i at veksle, holde regnskab og lægge sammen - alt sammen mens de hygger sig med spillet.
Mine elever oplever også spillet som en god social aktivitet, hvor de hjælper hinanden med at få vekslet inden monsteret kommer og napper alle deres enkroner.

Husk, der er mange flere gratis materialer på min hjemmeside.

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.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. Founding Fathers debated over how to govern the new nation, beginning with the Articles of Confederation: https://www.commonlit.org/text....s/articles-of-confed
When the Founding Fathers finally wrote the Constitution, they realized that they needed to add The Bill of Rights to get citizens on board with the new government: https://www.commonlit.org/texts/the-bill-of-rights

In which John Green kicks off Crash Course US History! Why, you may ask, are we covering US History, and not more World History, or the history of some other country, or the very specific history of your home region? Well, the reasons are many. But, like it or not, the United States has probably meddled in your country to some degree in the last 236 years or so, and that means US History is relevant all over the world. In episode 1, John talks about the Native Americans who lived in what is now the US prior to European contact. This is a history class, not archaeology, so we're mainly going to cover written history. That means we start with the first sustained European settlement in North America, and that means the Spanish. The Spanish have a long history with the natives of the Americas, and not all of it was positive. The Spanish were definitely not peaceful colonizers, but what colonizers are peaceful? Colonization pretty much always results in an antagonistic relationship with the locals. John teaches you about early Spanish explorers, settlements, and what happened when they didn't get along with the indigenous people. The story of their rocky relations has been called the Black Legend. Which is not a positive legend.

Permutations and Combinations tell us the number of different arrangements of items or numbers that can occur. In this lesson we look at the counting principle - a fast method of counting the number of various arrangements through multiplication.
In this video we also use combinations and permutation counting principles to answer some of the big questions of life - how many different outfit combinations do you have, how many lotto permutations are there, why do they call the tecmath the Count?
