A sequence is "converging" if its terms approach a specific value at infinity. This video is a more formal definition of what it means for a sequence to converge. Created by Sal Khan.

Hello Happy Friends!

Are you ready to learn?

I’m Sara, and today, we’re going to talk about… Well! Just listen!

Sounds good huh? Today, We’re going to talk about… Sound!

-

For sound to exist, there needs to be something, or someone that produces it. Like this guitar!

A medium through which it can be transmitted, like air.

And of course, an ear to receive it.

-

When I play my guitar strings…
I produce vibrations that travel in waves to our ears, that’s why we hear them.

-

Sounds’ speed depends on the medium it travels through.

In solids, like iron, sound waves travel at great speed!

In liquids, like water, they travel a little slower,

And in gases, like air, is where they travel the slowest.

-

But, if sounds are waves, why do we recognise sounds when we hear them?

Why do we recognise our parent’s voice? Or a dog’s bark?

Well it’s easy peasy! We recognise them because of every sound’s properties, or characteristics.

-

There are three properties:

Intensity, pitch and timber.

Intensity lets us identify if the sound is loud… or soft…

Thanks to the pitch, we can tell if the sounds are high (pitched) or low (pitched)

And by the timbre, we identify what or who has generated the sound.

For example, if it has been generated, by a flute…
…A guitar…
...A dog!...
...Or a cat!

-

Lastly, before I say goodbye, here’s a fun fact! Do you know what Echo is?

Echo, is when sound waves bump against an obstacle, change their direction and shortly after, we can hear the sound repeatedly.
-

That’s an echo, and I’m that you’ve heard it more than once. But if you haven’t... listen up!
Happy Learning!
So cool!

Bye happy friends!
I hope you’re always ready to learn more!

I wrote the lyrics to this one and put it to the tune of a familiar kids' song. I think it turned out well!

Notice that this is for the direct objects: it/them (lo,la,los,las). This video doesn't cover when a direct object is a person: me, you, him, her, them, us, you all

Also, do you like my t-shirt? I hand painted it for fun!

If you would like for me to come up with another song to help learn something grammatical or remember something you're studying, let me know!

Finding all of the missing lengths and angles of a right triangle can be confusing. With SOHCAHTOA, the Pythagorean Theorem, and Interior Angle Sum methods being hard to identify when to use each to find what you are looking for.

The examples in this video were chosen to help explain when to use the three methods and talks about the expected result of each method.

Paleozoic EraPaleozoic era was 544 to 245 million years ago
Paleozoic means “ ancient life” and is part of the phanerozoic eon along with the cenozoic, and mesozoic eras
Let’s hit some highlights of this era
Early during the Paleozoic era trilobites, echinoderms, and other marine invertebrates such as coral dominated the oceans.
Jawless fish also lived during this era
Evently sharks and other bony fish appear
However, as time passed life did not remain in the sea.
Land plants began to appear such as ferns and some trees later in this era
Life was also crawling out of the ocean
The first vertebrates appeared Among these vertebrates was a tetrapod which was a vertebrate that could live on land
Other vertebrates would appear including snakes,crocodiles,
Reptiles and insects scatter throughout the world and amphibians appear
The supercontinent Rodinia brook apart early in this era, but by the end of the era the supercontinent Pangea was formed.

They say money can't buy happiness, but who are they? Can money buy happiness? The answer is: sort of. While money may not be able to buy true happiness, lack of money can cause very real misery. Today, we look at the economics of happiness, and talk about how much money it takes to be happy. And where you should live to maximize your income-to-happiness ratio.

Subitize to 10. Subitize is the ability to tell the number of objects in a set, quickly, without counting. Subitizing develops math fluency, when students recognize sets without having to count each object and it helps develop number sense and the ability to perform mental math. Name the numbers in each set of dots, ten frames and fingers. This version of Subitize Rock does not show the numerals after each set.

Lyrics
Subitize, subitize
Use your brain
Use your eyes
See a set, then think quick
Say the number in the set

(Say the number of dots in each set)

Subitize, subitize
Use your brain
Use your eyes
See a set, then think quick
Say the number in the set

(Say the number in the ten frames)

Subitize, subitize
Use your brain
Use your eyes
See a set, then think quick
Say the number in the set

(Say the number of fingers)

Subitize, subitize
Use your brain
Use your eyes
See a set, then think quick
Say the number in the set

Is teaching teaching grammar to young children essential? Yes! It is vital to explain to young children how our language works. Learners will read and write better if they understand the fundamental building blocks of sentences. Nouns are an essential part of sentence structure because they form the subject in a sentence; without a subject, a sentence cannot be complete. After teaching nouns, your students should recognize that a noun is a name of a person, place, or thing. Also, they should be able to identify nouns in sentences. For this reason, teac hers should start by teaching nouns using simple words students can understand. Come along as we explain Nouns for Grade 1.

Everyone has played with a mixture of corn starch and water (or at least I hope they have). This was one of my favorite experiments as a kid. Your hand slides into the slime easily when moving slowly but the mixture behaves as a solid if you hit it quickly. That is what is meant by 'non-Newtonian' - the fluid's properties change depending on its relative motion. These properties can be exploited to dramatic effect as has been shown on speaker cones before. Here I wanted to understand what is going on, what frequencies and amplitudes work best so I used a slow-mo camera.

Thanks to everyone at the YouTube Space LA for helping me film this. I couldn't have done it without you.
