This week Craig Benzine talks about what happens when a case makes it to the Supreme Court of the United States (or the SCOTUS). We're going to focus on court procedure today. We talk about how to petition to get your case heard, how written arguments, or briefs, are made, what actually happens on the courtroom floor, and of course the variety of ways the SCOTUS issues opinions on cases.

En este vídeo para aprender español, para niveles intermedios, veremos la acentuación en el idioma castellano. Primera parte.


La sílaba tónica: Es la sílaba que tiene la fuerza dentro de la pronunciación de una palabra.

Por ejemplo en "madera" la sílaba tónica es la "DE" : maDEra

Dependiendo del lugar donde se encuentra la sílaba tónica la palabra puede ser:

Aguda
Grave o llaba
Esdrújula
Sobreesdrújula

Las agudas son las palabras cuya última sílaba es tónica, por ejemplo: BaLÓN, PaRÍS, VirREY,

Las llanas o graves son las palabras cuya penúltima sílaba es tónica, por ejemplo: TREbol, MARmol, MAdera.

Las palabras esdrújulas son las que su tercera sílaba empezando de atrás es tónica, por ejemplo: elecTRÓnica, MurCIÉlago, MÉdico.

Las sobreesdrújulas son las palabras cuyas cuarta sílaba empezando de atrás es tónica, por ejemplo reGÁlamelo, CÓMpramelo.


El primer paso para aprender las reglas de acentuación es saber diferenciar entre los distintos tipos de palabras.


Una vez que sabemos clasificar las palabras entre agudas, graves y esdrújulas, la acentuación es muy sencilla.


En la siguiente entrega de las reglas de acentuación veremos cómo saber si las palabras llevan acento o no, pero es imprescindible que sepas clasificarlas.

Finance and capital markets on Khan Academy: Hedge funds have absolutely nothing to do with shrubbery. Their name comes from the fact that early hedge funds (and some current ones) tried to "hedge" their exposure to the market (so they could, in theory, do well in an "up" or "down" market as long as they were good at picking the good companies). Today, hedge funds represent a huge class investment funds. They are far less regulated than, say, mutual funds. In exchange for this, they aren't allowed to market or take investments from "unsophisticated" investors. Some use their flexibility to mitigate risk, other use it to amplify it.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

So what's with those small, plastic cards that adults use to buy stuff? In Financial Literacy—Debit and Credit, your students will discover the answer to that question. They will also realize that credit cards and debit cards are different, and each one can be helpful in different ways.

Credit cards and debit cards are both small, hard, plastic cards. But apart from that, they are quite difference. Credit cards, for instance, are not linked to a bank account, but debit cards are. That means you can use debit cards to pay for things with money you already have. Generally speaking, a debit card is directly linked to a checking account. Credit cards use money that is loaned. You can use it to buy something and pay for it later.

Credit card companies issue credit cards, and it's like a type of loan. You can pay back the loan according to the credit company's schedule. You usually have to make a minimum payment each month to reduce your debt. They can also charge interest if it takes you longer to pay the money back or if you don't pay the full amount back every month. However, if you pay your credit card bills in full every month, you won't be charged any interest.

We hope you and your student(s) enjoyed learning about these important skills! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

It's Kids Academy and welcome back to our channel! Social studies for kids is an essential subject in their initial classes. The three very important lessons of social studies are recycling, civil rights and the right to vote. Let’s describe these concepts in simpler words for kids.

Recycling simply means converting waste material into something new that can be used effectively. There are many materials that are being recycled today including plastic bags, tin cans, bottles, thrown away paper, juice cartons, and many more. Recycling is important because it saves the earth from pollution and is an efficient use of energy.

Civil rights are the rights that are observed to protect the freedom of common people from the government, private individuals and social organizations. One of the very important rights given by civil rights is the right to vote.

Every person in a country, satisfying the legal requirements of nationality, has the right to vote and elect the political public representatives, mostly the president. Every person 18 years of age or older has the right to vote.
It is necessary for a kid to know their rights in a state, it enables them to have a better understanding of the law and defending themselves in times of need.

Students design and construct electromagnets that must pick up 10 staples. They begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. They conclude by designing their own electromagnets to complete the challenge of separating scrap steel from scrap aluminum for recycling, and share it with the class.

How Planets Rotate (Slow It Down to 0.25x to See 1 Hour in 1 Second)

The rotation periods of the planets cast to a single sphere. Rotations relative to background stars.

To measure a day is to count the amount of time it takes for a planet to completely spin around and make one full rotation. This is called a sidereal day. On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.

We know how long an Earth day is, but how about the other planets in our solar system? How long does it take for those planets to spin one full rotation? And what is the best way to show the answer to this question?

The simple answer is:

Mercury: 58d 16h, 10.83 km/h
Venus: 243d 26m, 6.52 km/h
Earth: 23h 56m, 1574 km/h
Mars: 24h 36m, 866 km/h
Jupiter: 9h 55m, 45,583 km/h
Saturn: 10h 33m, 36,840 km/h
Uranus: 17h 14m, 14,794 km/h
Neptune: 16h, 9,719 km/h


In this dataset, it's possible to see all 8 planets on the sphere rotating at once and we have set Earth's ~24 hour day/rotation to happen in 60 seconds. Next to each planet's name, we have listed the time it takes for each planet to make one full rotation as well as the speed each planet moves at its equator. Jupiter, for example, makes one rotation in 9h 55m but moves 27 times faster than Earth at its equator, spinning at a whopping 45,583 km/h!

We have included two PIPs (picture in pictures) that can be toggled on for further explanation related to this concept. A PIP of the approximate sizes of the planets relative to each other and a PIP illustrating that if you viewed all the planets from the same point and at an angular diameter of 30 degrees - about ten feet from the sphere - each planet would appear to have a similar size.

To understand the challenges of satellite construction, student teams design and create model spacecraft to protect vital components from the harsh conditions found on Mercury and Venus. They use slices of butter in plastic eggs to represent the internal data collection components of the spacecraft. To discover the strengths and weaknesses of their designs, they test their unique thermal protection systems in a planet simulation test box that provides higher temperature and pressure conditions.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of provided objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system, the ongoing objective in this unit.
